Answers for FAQs on Blood :

What is blood? How much blood does a person have ?

Blood is the red coloured fluid flowing continuously in our body’s circulatory system. About 1/12th of the body weight of a healthy individual is blood. On an average there are about 5 – 6 liters’ of blood present.

What is the composition of blood ?

Blood contains mainly a fluid called plasma in which are suspended cellular elements. Three types of cells: Red Blood Cells or RBC’s, White Blood Cells or WBC’s and tiny platelets form the cellular element.

What are the functions of these components ?

(a) Plasma: acts as a vehicle to carry many substances like glucose, fats and proteins, enzymes and hormones, etc., in addition to the blood cells.

(b) Red Cells: carry oxygen from lungs to various body tissues and take back carbon dioxide from the cells and tissues to be thrown out of body in the form of exhaled air.

(c) White cells: mainly act as body scavengers and guards. They help in the immune system of the body and act as defence forces of the body, killing the bacteria or any other organisms entering the body.

(d) Platelets: help in the clotting and coagulation of blood. We have experienced in our life that whenever we get injured the bleeding stops after a few minutes. This is brought about by a mechanism called clotting of blood in which platelets plays a very vital role.

How is blood formed ?

Blood consists of RBCs, WBCs, platelets suspended in plasma. In early embryonic life blood cells are formed in liver and spleen. But by the fifth month the Haemopoisis (i.e., formation of blood) occurs in bone marrow and lymphatic tissues. At birth the entire bone marrow is red and active. Gradually as the child grows, the marrow remains red only in the flat bones and vertebrae. The RBC, grannulocytes of WBC and platelets are produced mainly by bone marrow. The lymphocytes, monocytes, plasma cells are formed in the lymphoid and Reticulo Endothelial tissues. The orderly proliferation of the cells in the bone marrow and their release into circulation is carefully regulated according to the needs of body. Every day, new blood cells are being produced in the bone marrow and every day old cells are dying and being removed from the body.
Red blood cells have a life of 120 days and when it becomes old and senile it is thrown out. White cells live for a few days and platelets for a few hours. Thus, daily new cells are added to the circulation and old are removed from it.

What is haemoglobin ?

Haemoglobin is a substance present in the red cells. It is helpful in carrying oxygen and carbon dioxide. On an average, in a healthy male it should be between 14-16 gm % and in a female it should be about 12-14 gm %. This is also being daily synthesized and the new is replacing the old stock.

What are blood groups ?

Every individual has two types of blood groups. The first is called the ABO grouping and the second type is called Rh grouping.
In the ABO group there are four categories namely A Group, B Group, O Group and AB Group.
In the Rh Group either the individual is Rh-positive, or Rh-negative. Rh is a factor called as Rhesus factor that has come to us from Rhesus monkeys.

Thus, each and every human being will fall in one of the following groups.
A positive or A negative
B positive or B negative
O positive or O negative
AB positive or AB negative
There are also some sub groups as well as a few other classifications.

What is the importance of knowing the blood groups ?

For all practical and routine purposes, it is ideal to transfuse to the patient the same group of blood which he belongs to. It is only under very dire emergencies that we take O group as universal donor and AB groups as universal recipient. Under no circumstances O group can get any other blood except O. Similarly A group patient cannot be given B group blood and vice versa.

Why is A group not given B group blood ?

This is due to the reason that the blood of A Group people contains anti-B antibodies. In B group people there are anti-A antibodies. If we give A group blood to a B group patient, it is bound to be incompatible and will result in serious consequences.

Why are Rh negative and Rh positive incompatible ?

A patient with Rh-negative blood cannot be given Rh-positive blood as the antigen-antibody reactions will result in severe consequences.
In cases where a woman has Rh negative and her husband has Rh positive, the first child with Rh positive may be normal. But subsequently the woman may not conceive or may have repeated abortions. There may be intra uterine foetal death. If the child born is alive, it will suffer from a fatal disease called “Erythroblastosis Foetalis”. Now mothers can be given an injection of anti-D within 24 hours of the delivery of a Rh-positive child and thus protect the next baby from this catastrophe.

What is a unit of blood ?

Blood is collected in plastic bags which contain a watery fluid which prevents blood from getting coagulated. On an average we draw about 450 ml of blood from a person, depending on the weight of the donor. This blood, plus the amount of anti coagulant present in the bottle or bag, is known as one unit of blood.

Can blood of animals be transfused to human beings ?

Scientists have tried a lot but so far they are not successful. Only the blood of a human being can be transfused to a human patient.

How long can blood be stored ?

Whole blood can be stored up to 35 days, when kept in CPDA anti coagulant solution and refrigerated at 2-4 deg C. But the demand is so great that blood hardly ever remains in storage for so long and is used much before expiry. The various blood components can be stored as under.

  • - Platelet Concentrate – 5 days
  • - Platelet Apherises – 5 days
  • - Platelet Rich Plasma – 5 days
  • - Packed Cells – 35 days
  • - Fresh Frozen Plasma – 1 year
  • - Cryo Anti Hemophilic Factor – 1 year
  • - Cryo Poor Plasma – 5 years

Can we separate blood into its components ?

Yes! Now with technical advancements, we can make components of blood and store them. For example, plasma can be separated from whole blood and stored up to one year in frozen state at -80 deg C temperature or below. This is called Fresh Frozen Plasma. Similarly there are other components like Platelet Rich Plasma; Platelet Concentrate (can be stored as a life saving measure upto 5 days now at 22-24 degrees C in a platelet incubator and agitator); Cryoprecipitate (which is very useful in treating bleeding disorders due to the deficiency of factor VIII and IX); Factor VIII and IX; Albumin, Globulin and many others.

In most progressive blood banks more than 85% of the blood collected is converted into components and stored. This is because many patients do not require whole blood. For example, a patient whose haemoglobin is low and is therefore anaemic, may just require Packed Cells i.e. only red cells; a patient with burns may need more of plasma than cells; a patient with haemophilia may require only Factor VIII.

Now with the advent of cell-separators, we can directly draw a particular component from the donor, while rest of the blood constituents go back to the donor.


Answers for FAQs on Transfusion :

In which situations do patients need blood transfusion ?

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.

What are the common blood conditions ?

• Blood Conditions • Blood leaking out of blood vessels may be obvious, as from a wound penetrating the skin. Internal bleeding (such as into the intestines or after a car accident) may not be immediately apparent.
• Hematoma: A collection of blood inside the body tissues. Internal bleeding often causes a hematoma.
• Leukemia: A form of blood cancer, in which white blood cells multiply abnormally and circulate through the blood. The excessive large numbers of white cells deposit in the body`s tissues, causing damage.
• Multiple myeloma: A form of blood cancer of plasma cells similar to leukemia. Anemia, kidney failure and high blood calcium levels are common in multiple myeloma.
• Lymphoma: A form of blood cancer, in which white blood cells multiply abnormally inside lymph nodes and other tissues. The enlarging tissues, and disruption of blood`s functions, can eventually cause organ failure.
• Anemia: An abnormally low number of red blood cells in the blood. Fatigue and breathlessness can result, although anemia often causes no noticeable symptoms.
• Hemolytic anemia: Anemia caused by rapid bursting of large numbers of red blood cells (hemolysis). An immune system malfunction is one cause.
• Hemochromatosis: A disorder causing excessive levels of iron in the blood. The iron deposits in the liver, pancreas and other organs, causing liver problems and diabetes.
• Sickle cell disease: A genetic condition in which red blood cells periodically lose their proper shape (appearing like sickles, rather than discs). The deformed blood cells deposit in tissues, causing pain and organ damage.
• Bacteremia: Bacterial infection of the blood. Blood infections are serious, and often require hospitalization and continuous antibiotic infusion into the veins.
• Malaria: Infection of red blood cells by Plasmodium, a parasite transmitted by mosquitoes. Malaria causes episodic fevers, chills, and potentially organ damage.

How much blood is required for each disease ?

  • - A liver transplant patient, on average, will need six - 10 units of red blood cells, 20 units of plasma and 10 units of platelets (or one - two units of apheresis platelets).
  • - A kidney transplant patient, on average, will need one - two units of red blood cells.
  • - A heart transplant patient, on average, will need four - six units of red blood cells.
  • - An adult open-heart surgery patient, on average, will need two - six units of red blood cells, two - four units of plasma and one - 10 units of platelets (or one - two units of apheresis platelets).
  • - A newborn open-heart surgery, on average, will need one - four units of red blood cells, one - two units of plasma, and one - four units of platelets.
  • - Prostate cancer surgery may require two - four units of red blood cells.
  • - Abdominal aortic aneurysm may require four - six units of red blood cells.
  • - Bone marrow transplant, on average, requires one - two units of red blood cells every other day for two - four weeks and six - eight units of platelets daily (or one - two units of apheresis platelets) for four - six weeks.
  • - A leukemia patient may need two - six units of red blood cells and six - eight units of platelets (or one - two units of apheresis platelets) daily for two - four weeks. Patients with sickle cell disease, on average, need 10-15 units of red blood cells to treat severe complications.
  • - A premature newborn may need one - four units of red blood cells while in Intensive Care.

Do you test all the collected blood ?

Yes! Now with technical advancements, we can make components of blood and store them. For example, plasma can be separated from whole blood and stored up to one year in frozen state at -80 deg C temperature or below. This is called Fresh Frozen Plasma. Similarly there are other components like Platelet Rich Plasma; Platelet Concentrate (can be stored as a life saving measure upto 5 days now at 22-24 degrees C in a platelet incubator and agitator); Cryoprecipitate (which is very useful in treating bleeding disorders due to the deficiency of factor VIII and IX); Factor VIII and IX; Albumin, Globulin and many others.

Now with the advent of cell-separators, we can directly draw a particular component from the donor, while rest of the blood constituents go back to the donor.

Can we separate blood into its components ?

Yes. ALL the blood in the blood bank is tested for following, using the latest technology: Hepatitis B & C Malarial parasite HIV I & II (AIDS) Venereal disease (Syphilis) Blood Group Before issuing blood, compatibility tests (cross matching) is done. Please note that test results are highly confidential and not shared with anyone. In case of identification of any disease, result is shared with the donor only.

What happens to patients in transfusions with incompatible blood (mismatched blood) ?

The following symptoms may occur after only a few â ml of blood have been given:
1. Patient complains of shivering, restlessness, nausea and vomiting. There is precardial and lumbar pain.
2. Cold, clammy skin with cyanosis.
3. Pulse rate increases, respiratory rate increases. Temperature increases to 38 to 40 deg C. [101 to 105 F].
4. Blood pressure falls and patient passes into a state of shock.
5. 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)
6. Jaundice appears after a few hours and in some cases anuria persists and uremia develops. This may lead to death.


Answers for FAQs on Donating Blood :

Why should I voluntarily donate blood ?

Human blood is produced only by the human body and cannot be synthesized. Blood requirements of patients who have blood loss due to major accidents or diseases or due to surgery can only be met by blood donation. Hence it is the duty of each of us to donate blood and help each other in our times of need.

In which situations do people generally donate blood ?

There are three types of blood donors: –
(1) PROFESSIONAL DONORS – They sell their blood, which can be infectious and can transmit very dangerous diseases to the recipient. It is illegal to take blood from any professional donor.
(2) REPLACEMENT DONATION – Healthy relatives and friends of the patient give their blood, of any group, to the blood bank. In exchange, the required number of units in the required blood group is given.
(3) VOLUNTARY DONATION- Here a donor donates blood voluntarily. The blood can be used for any patient even without divulging the identity of the donor. This is the best type of blood donation where a motivated human being gives blood in an act of selfless service.

What are the benefits of blood donation to me ?

Every time you donate a unit of blood at a blood bank, which is a member of the association of Voluntary Blood Banks, you will receive a certificate and a Blood Donation Card. This card can be used by you to get blood from the registered blood bank when you have a need. Also, every time you donate blood, screening tests are done on the blood for jaundice, hepatitis, AIDS etc. Hence, you are able to get screened for these communicable diseases free of charge. And, of course, most important of all, every time you donate blood you get the satisfaction of helping a fellow human being in his/her time of need. You will be donating a little of your blood to save someone's life.

Is it safe to donate blood and what happens during blood donation ?

Donating blood is safe and simple. We use only totally sterile disposable blood bags and needles. The actual donation process works like this: - You will complete a donor registration form that includes your name, address and a few other details.
- You will be asked a few questions about your health.
- You will go through a simple medical checkup including blood pressure, and pulse.
- A drop of blood will be obtained from your finger tip to test for Hemoglobin% and your group.
- You will proceed to a donor bed where your arm will be cleaned with antiseptic.
- During the donation process, you will donate 350ml or 450ml depending on your weight.
- After the process is over, you will rest for about 5 minutes.
- Following your donation, you will be given refreshment.
Please, remember to take your donor card

Who is a healthy donor ?

Some basic health conditions have to be met by donors: A donor should : - Be above 18 years and below 60 years of age.
- Have a haemoglobin count that is not less than 12.5 g/dl
- Weigh not less than 45 kgs
- Have normal body temperature at the time of donation
- Have normal BP at the time of donation
- Should be free of any disease at the time of donation

Does a donor need to do anything special before donation ?

We want your donation experience to be pleasant. Please remember :
Eat well-balanced food  before you donate. You should not be on an empty stomach.
Tell us the name and dosage of any medications you are taking. Medications will not keep you from donating, but the reason for taking them might.
If you have taken alcohol within 24hrs you cannot donate.

How long does the donation take ?

The procedure is done by skilled, specially trained doctors/nurses and takes three to eight minutes. However, from start to finish (filling form, post donation rest, etc) the entire process should take 30 to 40 minutes.

Does the needle hurt the entire time ?

There may be a little sting when the needle is inserted, but there should be no pain during the donation.

Does the donor suffer from any harmful effects after donating blood donation ?

Absolutely not, rather a donor after having given blood voluntarily gets a feeling of great pleasure, peace and bliss. Soon, within a period of 24-48 hours, the same amount of new blood gets formed in the body, which helps the donor in many ways. His own body resistance improves, the circulation improves, and he himself feels healthier than before.

Does a donor need to rest after donating blood ?

Yes. The donor needs rest, preferably lying down, so that the amount of blood that has been donated soon gets poured into the circulation from the body pools in a natural way. The donor should take it easy for about 10-15 minutes.

Can a donor work after donating blood ?

Of course! Routine work is absolutely fine after the initial rest. Rigorous physical work should be avoided for a few hours.

What special diet should a donor follow after giving blood ?

After resting for a while a donor is given some liquid (fluid) to take. It may be a cup of coffee or milk or fruit juice along with a few biscuits or fruit. The donor needs no other special diet. A routine balanced diet is adequate. The donor’s blood gets replenished within 24-48 hours.

How long will it take for the body to replenish the blood ?

The body replaces blood volume or plasma within 24 hours. Red cells need about 21 days for complete replacement.

How frequently a donor can donate blood ?

A healthy person can donate after every 56 days. Three months time between donations is a very safe interval.

Do any diseases debar a donor from giving blood ?
