Blood Basics

Know what the components of blood, how blood works in the body and more..

The Bombay blood group is a rare exception to the commonly accepted ABO blood types. It is observed to occur in 1 out of every 250,000 people except in parts of India where the incidence has been observed to be as much as 1 in 7600. The rare designation was first identified in Mumbai, also known as Bombay - thus the name of the blood group. The blood type is thought to occur in only those of (Eastern) Indian descent. Blood types are actually ways of differentiating the type of antigens on a person's red blood cells. Being able to match these during donation and transfusions is important because of potential rejection by the immune system. The Bombay blood group is missing an antigen present on cells of the ABO group, the H antigen. The H antigen is a carbohydrate known as fucose.

The ABO blood types, discovered around 1900, consist of A and B antigen which are derived from H antigen, also known as the H substance. Type A has A antigen, type B has B antigen, and type O has neither A nor B antigens. The difference though is that in type O, the H antigen is present, it just is not changed by enzymes and used in blood cell recognition. In Bombay blood type (phenotype hh or Oh) there is no H antigen and those individuals actually have antibodies against the H substance. Bombay blood cells will act like type O when tested for antigens, but the tests currently only look for A and B groupings. Proper blood typing will not identify the Bombay blood group. Specialists point out that reverse grouping, whish are cross comparisons with type O, or serum grouping would have to be done to determine if a person had the rare blood type

Bombay blood groups can donate to any other blood group (with Rhesus compatibility positive or negative) because there is no fear of an immune reaction against antigens, but they must receive only hh blood otherwise face an hemolytic transfusion reaction which is often fatal. The hh phenotype is the inheritance of two recessive alleles (h) of the H gene and is attributed to a deficiency of the enzyme known as fucosyl transferase

Haemoglobin is the iron-containing protein attached to red blood cells that transports oxygen from the lungs to the rest of the body. Haemoglobin bonds with oxygen in the lungs, exchanges it for carbon dioxide at cellular level, and then transports the carbon dioxide back to the lungs to be exhaled.Whether haemoglobin binds with oxygen or carbon dioxide depends on the relative concentration of each around the red blood cell. When it reaches the oxygen-rich lungs, it releases the less-abundant carbon dioxide to bind with oxygen; when it goes back out into the body where cells are producing carbon dioxide, it releases the oxygen and binds with carbon dioxide.Haemoglobin abnormalities result in very serious hereditary diseases, such as sickle-cell anaemia and thalassemia.Haemoglobin is made up of four subunits, with a haem (iron-containing) group in each for oxygen binding. There are slightly different haemoglobins in adults when compared to children and foetuses.The level of haemoglobin is measured to check the oxygen carrying capacity of the blood. The low oxygen carrying capacity of the blood leads to the symptoms of anaemia (low level of haemoglobin).

The human immune system has various ways of responding to an infection caused by bacteria or viruses. Our bodies produce proteins (antibodies) that are highly specific for the infectious agent as a part of our "humoral" immune response. The antibodies help stop the infection from spreading further and help to eliminate the bacteria or virus from the body.Antibodies are also used to help our bodies find and destroy "foreign" cells such as tumors.
Because antibodies bind tightly to only one type of structure on the surface of cells (antigen), they can also be useful for identifying different types of blood cells. It is important to correctly identify blood cells in our bodies if we ever need to receive blood from someone else because we are sick (transfusion). Our blood type is determined based on the presence or absence of two proteins on the surface of our red blood cells (Type A and Type B). There are four possible combinations of blood types namely: Type A, Type B, Type AB, and Type O (contains neither A nor B proteins). This is referred to as the ABO blood type. In addition, red blood cells have a Rhesus factor or Rh, which is either present or absent. If the Rh factor is present, the cells are referred to as Rh positive. Including both the ABO and Rh systems for blood typing, there are a total of 8 possible blood types.

The blood moves through the body through the blood vessels -- essentially, flexible tubes that branch out and subdivide. There are different types of blood vessels: the arteries, capillaries, and veins.

Arteries carry the oxygen-rich blood that the heart pumps to the rest of the body. The heart pumps the blood out through one main artery, the dorsal aorta. This branches out into smaller arteries, which branch out in turn. The smallest arteries are called arterioles, and connect to capillaries. Because the arteries carry large quantities of blood that is under high pressure from the beating of the heart, they are wide and thick. The walls of an artery consist of three layers: a tough outer layer, a middle layer of muscle, and a smooth inner layer through which the blood can flow easily. The muscles in the middle layer help the heart pump the blood, squeezing down to move the blood along. You can feel the pulsing of the arteries as your pulse.

Blood passes from the arterioles into the capillaries. Capillaries are very narrow -- only one cell wide. They have very thin walls made of overlapping flat cells called endothelium; the walls are thin so that oxygen and carbon dioxide can pass through them easily. Inside the capillaries, the red blood cells release their oxygen, which passes through the capillary walls and into the surrounding tissue. The tissue releases its waste products, like carbon dioxide, which passes through the capillary walls and into the red blood cells.

Some organs -- the liver, spleen, and bone marrow -- contain blood vessels called sinusoids instead of capillaries. Like capillaries, sinusoids are composed of endothelium. Sinusoids are a bit larger than capillaries.From the capillaries/sinusoids, the de-oxygenated, waste-laden blood passes into the veins for its return trip to the heart. Veins are like arteries in that they have three layers. But since the blood is not under as much pressure, the walls of veins are thinner. Veins contain one-way valves to keep the blood flowing toward the heart, even against the pull of gravity. Because the blood in veins contains so little oxygen, it appears bluish rather than bright red. That's why the veins you can see through your skin (for example, in the underside of your wrist) are blue.

Plasma is the transporting medium for a myriad of hormones, electrolytes, sugars, waste products, and other substances. It is especially useful in transfusion medicine, as it provides the starting material for the preparation of critical blood-clotting factors, albumin and immune protein preparations. The clotting factor concentrates, prepared from large batches of pooled plasma, provide life-saving treatment for blood clotting disorders such as hemophilia. Plasma is a clear, straw-colored liquid that carries the blood cells and various hormones, nutrients, and so on through the body. It makes up a little more than half of the total blood volume. Plasma is about 90 percent water. Much of the other ten percent comprises various kinds of protein molecules, including enzymes, clotting agents, immunoglobulins (part of the immune system), and proteins that carry hormones, vitamins, cholesterol, and other things the body needs. Plasma also contains sugar (glucose) and electrolytes like sodium, potassium, and calcium, as well as other things like the aforementioned hormones, vitamins, and cholesterol.

The blood cells called platelets (thrombocytes) help blood to clot, in several different ways. When bleeding occurs, platelets clump together to help form a clot. Also, when they are exposed to air (as they would be by a wound), platelets start breaking down and release a substance into the bloodstream. This substance starts a chain of chemical events that eventually causes a protein in the blood, fibrinogen, to turn into a different substance, fibrin, which forms long threads. These threads tangle up red blood cells to help form a clot, or scab, over the wound. In their "resting" state, platelets look like two plates stuck together (hence the name). When "activated" and helping to form a clot, they change shape and look like tiny roundish blobs with tentacles. At only two to three microns, they are the smallest kind of blood cell.

White Blood Cells are responsible for protecting the body from invasion by foreign substances such as bacteria, fungi, and viruses. The majority of white blood cells are produced in the bone marrow, where they outnumber red blood cells by two to one. However, in the blood stream, there are about 600 red blood cells for every white blood cell. There are three types of white blood cell: granulocytes, lymphocytes, and monocytes. There are, in turn, three kinds of granulocyte: neutrophils, eosinophils, and basophils. (Granulocytes are called that because they contain granules that hold digestive enzymes.) Neutrophils kill invading bacteria by ingesting and then digesting them. Eosinophils kill parasites, and are involved in allergic reactions. Basophils also function in allergic reactions, but are not well understood. Lymphocytes are key parts of the body's immune system. There are two kinds of lymphocyte: T cells and B lymphocytes. T cells direct the activity of the immune system. B lymphocytes produce antibodies, which destroy foreign bodies. Monocytes, the largest kind of white blood cells, enter the tissues of the body and turn into even larger cells called macrophages. These eat foreign bacteria and destroy damaged, old, and dead cells of the body itself.

Red Blood Cells are perhaps the most recognizable component of whole blood. Red blood cells contain hemoglobin, a complex iron-containing protein that carries oxygen throughout the body and gives blood its red color. The percentage of blood volume composed of red blood cells is called the “hematocrit.” The average hematocrit in an adult male is 47 percent; the average hematocrit in adult females is 42 percent. There are about one billion red blood cells in two to three drops of blood, and, for every 600 red blood cells, there are about 40 platelets and one white cell. Manufactured in the bone marrow, red blood cells are continuously being produced and broken down. They live for approximately 120 days in the circulatory system and are eventually removed by the spleen. Red blood cells are prepared from whole blood by removing the plasma, or the liquid portion of the blood. They can raise the patient's hematocrit and hemoglobin levels while minimizing an increase in volume. Red blood cells are shaped like tiny doughnuts, with an indentation in the center instead of a hole. They contain a special molecule called hemoglobin, which carries the oxygen. In the lungs, where there is a lot of oxygen, the hemoglobin molecules loosely bind with oxygen. Each molecule of hemoglobin contains four iron atoms, and each iron atom can bind with one molecule of oxygen, allowing each hemoglobin molecule to carry four molecules of oxygen. In the capillaries, where there is little oxygen, the hemoglobin readily sheds the oxygen it is carrying and allows it to be absorbed by the body's cells. The iron in hemoglobin is what makes blood red.
Patients who benefit most from transfusions of red blood cells include those with chronic anemia resulting from disorders such as kidney failure, malignancies, or gastrointestinal bleeding and those with acute blood loss resulting from trauma or surgery. Since red blood cells have reduced amounts of plasma, they are well suited for treating anemia patients who would not tolerate the increased volume provided by whole blood, such as patients with congestive heart failure or those who are elderly or debilitated. Improvements in cell preservative solutions over the last 15 years have increased the shelf life of red blood cells from 21 to 42 days. Red blood cells may be treated and frozen for extended storage (up to 10 years).

Whole Blood is a living tissue that circulates through the heart, arteries, veins, and capillaries carrying nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the body's tissues. Whole blood contains red blood cells, white blood cells and platelets suspended in a fluid called plasma.If blood is treated to prevent clotting and permitted to stand in a container, the red blood cells, weighing the most, will settle to the bottom; the plasma will stay on top; and the white blood cells and platelets will remain suspended between the plasma and the red blood cells. A centrifuge may be used to hasten this separation process. The platelet-rich plasma is then removed and placed into a sterile bag, and it can be used to prepare platelets and plasma or cryoprecipitated AHF. To make platelets, the platelet-rich plasma is centrifuged, causing the platelets to settle at the bottom of the bag. Plasma and platelets are then separated and made available for transfusion. The plasma may also be pooled with plasma from other donors and further processed, or fractionated, to provide purified plasma proteins such as albumin, immunoglobulin (IVIG) and clotting factors.

Blood cells are produced in the bone marrow, a jellylike substance inside the bones that is composed of, among other things, fat, blood, and special cells that turn into the various kinds of blood cells. In children, the marrow of most of the bones produces blood. But in adults, only the marrow of certain bones -- the spine, ribs, pelvis, and some others -- continues to make blood. Bone marrow that actively produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.

All blood cells come from the same kind of stem cell, which has the potential to turn into any kind of blood cell. These stem cells are called pluripotential hematopoietic stem cells.

As the blood cells develop from the stem cells in the marrow, they seep into the blood that passes through the bones and on into the bloodstream. The different kinds of blood cells have different "life spans" -- red blood cells last about 120 days in the bloodstream; platelets about 10 days; and the various kinds of white blood cells can last anywhere from days to years. The body has a feedback system that tells it when to make new red blood cells. If bodily oxygen levels are low (as they would be if there are too few red blood cells circulating), the kidneys produce a hormone called erythropoietin, which stimulates the stem cells in the marrow to produce more red blood cells.

Whole blood is separated into its component parts for patients needing a particular product. The main blood collection bag has up to three satellite bags attached to it. In a centrifuge process, the red cells, platelets, and plasma are spun, separated and readied for transfusion.
• Red blood cells are made in the bone marrow and carry oxygen to the body and remove carbon dioxide. They are needed for accident victims, certain surgeries, and patients with anemia and blood disorders.
• Platelets are tiny cells, formed in the bone marrow, that control bleeding by helping the blood to clot. The body replaces platelets within 72 hours of donation. Leukemia and cancer patients need platelets because chemotherapy destroys their own supply of platelets.
• Plasma is the liquid part of the blood and makes up 55% of blood volume. It is comprised of 92% water, 7% protein, and 1% minerals, and is essential in the clotting/coagulation process. Plasma is used for patients experiencing heavy bleeding and for burn victims.
• Cryoprecipitate is extracted from plasma in a freezing and thawing process. This component contains a specific clotting agent, Factor VIII, missing in hemophiliacs and essential for controlling bleeding.

Blood Transfusion

These are a set of questions related to the transfusion of blood to the patient.

The following symptoms may occur after only a few ml. of blood have been given:

• Patient complains of shivering, restlessness, nausea, and vomiting. There is precardial and lumbar pain.
• Cold, clammy skin with cyanosis.
• Pulse rate increases, respiratory rate increases. Temperature increases to 38 to 40 deg C. [101 to 105 F].
• Blood pressure falls and patient passes into a state of shock.
• Haemoglobinaemia, haemoglobinurea (urine turns red); oliguria (urine becomes scanty or the urinary output is reduced) and anuria (total output of urine becomes 200 ml. a day)
• Jaundice appears after a few hours and in some cases anuria persists and uremia develops. This may lead to death

There are many situations in which patients need blood to stay alive:
• A patient needs blood after a major accident in which there is loss of blood.
• No major surgery is performed without blood as there is bound to be blood loss.
• On an average, for every open heart surgery about 6 units of blood is required.
• In miscarriage or childbirth, cases the patient may need large amount of blood to be transfused for saving her life and also the child's.
• For patients with blood diseases like severe Anaemias especially Aplastic Anaemias, Leucaemias (blood cancer), Haemophilia (bleeding disorder), Thalassemia etc. repeated blood transfusions are the only solution.
• In many other situations like poisoning, drug reactions, shock, burns, blood transfusion is the only way to save precious human life.

Donating Blood

All you wanted to know about blood donation.

As you know, blood is a life saving medicine, which works wonders in certain medical treatments, and life threatening situations. It is an in emergency medicine. Our society is today threatened by scarcity of voluntary blood donors. The only source of blood right now is human beings. The issue has got further complexes by the professional donors, who donate blood for money. These donors have contributed towards rapid spread of killer diseases like AIDS, Hepatitis B and hepatitis C in the society. WHO strongly recommends voluntary blood donation. Your regular donation will go a long way in salvaging the situation.

  • Ensure that you have slept well
  • Drink a lot of water and eat something substantial and healthy.
  • Do not smoke within 2 hours of donating.
  • Do not consume alcoholic drinks within 12 hours of donation
  • Relax!
  • Age: 18-60 years

  • Weight: At least 45kgs for men as well as women

  • Well-Being: Must feel healthy that particular day (i.e. must not have a cold or cough or must not be on any medication)

  • Haemoglobin: Minimum 12.5 mg/dl

Giving blood is a very simple and straight forward process.

  • On arrival at a blood bank, you will be asked to fill a few details on a donor form.

  • After you pass this simple medical screening process, you will be escorted to a blood donation area. The actual blood donation takes about 10 minutes.

  • While the blood is being taken you must keep pressing the sponge provided. That ensures good blood circulation.

  • Please do not get up immediately after donating blood. You must allow the blood flow in the body to normalize by lying down for 5 more minutes. This also prevents dizziness.

  • This is followed by a little refreshment.

  • Please do not forget to collect your certificate of appreciation.

  • You can resume with your daily work immediately after donation.

  • The blood you donate is tested and separated into components before being made available to the patients.

  • Any abnormality found is reported to you if you have chosen to receive the same.

  • Eat and Drink something before leaving.
  • Drink more liquids than usual in next 4 hours.
  • Avoid consuming alcohol until you have eating something.
  • Don't smoke for next 30 minutes.
  • If there is bleeding from the phlebotomy site, raise the arm and apply pressure.
  • If fainting or dizziness occurs, either lie down or site with the head between the knees.
  • Resume all normal activities if no symptoms occur ?? Remove bandage next day.
  • Do not take stairs immediately.
  • Do not go for any rigorous exercise for next 24 hrs especially lifting heavy weight from the ground after you donated blood.

In modern medicine there is no room for whole blood. Developed countries have switched over to blood components for more than 20 years. Unfortunately in India still 95% of the blood is used as whole blood. By making blood components, all the useful parts of blood can be used. In whole blood, platelets die and clotting factors become ineffective and the patient receives unwanted and ineffective components.

The three components of blood are Packed cells, Plasma and Platelets. The specific requirements of these components are:

  • Packed cells (life span of 20-40 days) - In case of anemia, Blood loss due to bleeding.
  • Plasma (life span of more than a year) - For clotting disorder.
  • Platelets (life span of 5-6 days) - Low platelets count, Clotting disorders, Dengue fever, Burn cases, etc.

Safe blood does not only depend on application of science and technology but also on you. It is impossible to screen blood for all the possible diseases and infections. Therefore a donor registration form has been provided to you. Please fill this form very carefully. If you have any reason to suspect that you may not be an eligible blood donor, please feel absolutely free to clarify the same with the staff. It is us who can ensure a regular and safe supply of blood.

Blood donation gives, a proud feeling of touching someone’s life in such a beautiful way. Its an experience that no words can define. You have to donate blood yourself to find out. By keeping the blood line flowing, you will greatly contribute towards a healthier, happier society. Do remember, any one may require blood any time. Including ourselves and our dear ones.

We keep the information you provide us strictly confidential. The information is used for no purpose other than stated.

That is impossible. Only sterile disposables are used to collect your blood. These disposables can be used only one time. This totally eliminates any remote chance of catching any disease from blood donation.

No ! Not really. Do ask any regular blood donor about it. A small percentage of first time donors may psychologically feel a little dizzy but only for a few minutes. Staff at the blood drive will ensure that your first blood donation is a happy experience. We are sure this will make you a regular blood donor. In fact there are many people who have donated more than 100 times in their life time.

It reduces the chances of ischemic heart diseases (beginning of heart problems) as frequent donations reduce the accumulated and unwanted iron load from the body.

Anything, but preferably something. Eating light snacks and a drink (nonalcoholic) before blood donation makes you psychologically more comfortable.

Yes!. If only 3% of our people started donating blood regularly, there would be no blood shortage. You can help in a big way by promoting voluntary blood donation. Encourage your friends, family members and colleagues to come forwards and donate blood regularly. Whenever possible arrange for a blood donation camp.If we achieve 100% voluntary blood donation, then blood
transfusion will become safer and much better.

No!. Most of the reasons for asking a donor not to donate are based on temporary medical conditions. There are some medical problems which have a defer period in which you will not be allowed to donate blood. It is best to ask the staff and find out when next will you be in a position to donate.

Eligible donors (any body between 18 to 60 years of age and leading a healthy life) with weight above 50 kgs. can donate up to 450 ml of blood. Your body can replenish this volume within 24 hours.

The amount of blood which can be donated is based on the weight:
45 - 55 kgs: 350 ml.
More than 55 kgs: 450 ml.

  • Blood Donation Is Good to Reduce the chance of heart diseases
  • Enhance the production of new Red Blood Cells
  • Helps in fighting hemochromitosis
  • Burns calories
  • Invigorated feeling in elderly people
  • Basic blood test is done

In the past, type O Blood was given to virtually anyone except those that were termed 'rare' Blood. Donors of Blood group O were always referred to as 'universal donors'. Today, because of new research and a better understanding of the complex issues regarding immune reaction related to incompatible donor Blood cells, type O Blood is no longer seen suitable.

There is no "Universal Donor."
With further research, it was seen that even O- donors have some antibodies in their blood that can cause reactions in the recipients. Doctors/nurses now combine or cross-match a small sample of the donor's blood with that of the recipient's to check if they are compatible.

The terms universal donor and universal recipient are an over-simplification, because they only consider possible reactions of the recipient's anti-A and anti-B antibodies to transfused red blood cells, and also possible sensitization to RhD antigens (the Rhesus factor or Rhesus D antigens

Possible reasons for low levels of hb:
Malnutrition and nutritional deficiencies of iron, folate, vitamin B12, vitamin B6
Red blood cell destruction due to a transfusion reaction
Haemorrhage (bleeding)
Lead poisoning
Excessive intake of fluids (over hydration – temporary dilution of haemoglobin level)

Possible reasons for higher levels of Hb:
Congenital heart disease
Lung diseases like cor pulmonale and lung fibrosis
Polycythemia vera or increased RBC formation due to excess of erythropoietin.

Whole blood donors may give once every three months in order to allow plenty of time to replenish their red cells. Apheresis platelet donors can donate more frequently, as much as every seven days, up to 24 times per year, because the platelet and plasma components are replaced in the body more quickly than red cells. Blood volume or plasma is replaced within 24 hours. Red cells need about 4-5 weeks for complete replacement.

The donor's blood type must be determined if the blood will be used for transfusions. The collecting agency usually identifies whether the blood is type A, B, AB, or O and the donor's Rh (D) type and will screen for antibodies to less common antigens. More testing, including a crossmatch, is usually done before a transfusion. Group O is often cited as the "universal donor" but this only refers to red cell transfusions. For plasma transfusions the system is reversed and AB is the universal donor type. Donated blood is tested by many methods, but the core tests recommended by the World Health Organization are these four:

  • Hepatitis B
  • Hepatitis C

  • HIV

  • Syphilis

  • Malaria
  • Platelets Donation

    Get to know more about the process of donating platelets selectively.

    By donating your platelets through platelet apheresis (ay-fer-ee-sis), you give a very special gift of life. Most patients undergoing a bone marrow transplant, surgery, chemotherapy, radiation treatment or organ transplant need platelets in order to survive. In fact, doctors are finding that platelets play a vital role in more and more new therapies. With just a five-day storage life, platelet donations are delivered quickly to the patients who need them. Platelet donors have the satisfaction of knowing that their donation will be saving a life within just a few days.

    Until recently, the only way to collect enough platelets for a single transfusion was to take blood donations from 5 to 10 donors, separate the platelets from the other blood cells, and combine the platelets to obtain a large enough quantity for transfusion. Today, sophisticated medical equipment — blood cell separators — can collect enough platelets for transfusion from a single donor. Using a technique called apheresis, blood is drawn from the donor's vein into an apheresis instrument, which separates the blood into separate portions by centrifugation.

    By appropriately adjusting the instrument, a selected portion of the blood, such as the platelets, can be recovered, while the rest of the blood is returned to the donor either into the same vein or into a vein in the other arm.
    This process takes more time than whole blood donation, but the percentage of platelets is much greater. It is a simple, safe process — very much like regular blood donation. In fact, your body starts replenishing platelets immediately after your donation. Within 48 hours, your body's platelets should be completely replenished.

    Blood is made of four components: platelets, plasma, red blood cells and white blood cells. The platelet component is necessary to control bleeding. Patients undergoing chemotherapy and radiation treatments, for example, are unable to produce enough platelets. Without platelet transfusion, life-threatening hemorrhages could result.

    By using a special method called apheresis, whole blood is separated into components, and the platelets are removed. Specially trained staff conduct the procedure while you relax, watch TV or read. The entire process takes about two hours.

    Unfortunately not every one who is a blood donor can give platelets.
    * You need to have given blood without any problems such as fainting or bruising.
    * We need platelet donors of groups O, A and B. (Group AB patients can receive group A platelets).
    * There is a lower age limit of 18 as donors need to give whole blood without problems first. There is an upper limit of 60 for new platelet donors, and existing donors may continue to age 65 (the procedure puts more of a strain on the circulation than whole blood donation).
    * Your weight must be greater than 60 kg to be able to donate platelets.
    * You should not be on aspirin or any of the anti-inflammatory painkillers such as ibuprofen. These drugs stop the platelets working properly.
    * Platelet donors are asked to attend regularly - at least 8-10 times per year. We understand some people are unable to do this because of the travelling and time commitment.

    A cuff is placed around your arm, the skin cleaned, local anesthetic may be injected and the donation needle inserted. Depending on the type of machine used a needle may be put in both arms. Blood samples are taken at this stage for testing in the same way as whole blood donations. Additional tests carried out for platelet donors are to check your general state of health, in particular, to check your platelet count and to determine your tissue type (so that your platelets can be matched to those of a particular patient if needed).

    During the procedure, blood is withdrawn, mixed with anticoagulant to prevent clotting and processed by spinning to separate the platelets. The rest of the blood is returned to you, which is why it is safe for you to donate at a much higher frequency than whole blood (as often as every 2 weeks!).

    During the procedure, any white cells that remain in your platelet donation are also removed as these could cause problems in a patient despite being harmless to you.All the tubing that blood comes into contact with is sterile and disposable. There is, therefore, no risk of 'catching' any infection.

    Also, during the return of your blood, air detectors ensure that none of the sterile air present in the collection gets passed into your vein. If a detector identifies air, the machine will automatically shut down and can only be restarted when the air has been removed. While you are donating you will be monitored and cared for by qualified staff supervised by nurses. You can read, chat to the staff or relax and you will be offered refreshments. When the procedure is completed the needle(s) will be removed and a dressing applied to the venepuncture site(s). Following the donation, which should take approximately 90 minutes, you will be able to take a well earned break in our rest area and enjoy some more refreshment if you wish.

    Because platelets are quickly replenished by your body, you can donate platelets as frequently as every 48 hours, but no more than 24 times a year. Additional restrictions vary, however, depending on the donation center, type of procedure used, and your donation history.
