What happens to blood without platelets after donation?

Wednesday, 19/10/2016

Three types of blood cell groups exist in the human blood stream. These are as follows:

●Red blood cells
●White blood cells

Platelets are the tiniest of the three types available, and they are produced by the bone marrow to clot blood whenever it comes in contact with the atmospheric air through a wound, injury, cut, etc. This process prevents bleeding in excess and safeguards the human’s blood.

1.Normal, low and high platelet count

The range between which the platelet count of any normal human should lie per milliliter of blood is 1,50,000 to 3,50,000. A difference in the count of platelets due to any medical reason can prove to be fatal for the human for excessive bleeding in the absence of clotting of blood can lead to death.

If a person has low or high platelet count, then they have the following medical conditions:


Thrombocytopenia is the condition wherein the number of platelets per microliter of blood lies below the usual 1,50,000. In such a case, the person suffers from getting easily bruised, frequent nose bleeds or mouth and gum bleeding, and rashes over the skin.


In this condition, the number of platelets in a single unit microliter of blood lie above 3,50,000.


2.Donation of blood and platelets

Donating blood is an interestingly noble task on behalf of someone who could potentially play a significant role in saving a stranger’s life. Not necessarily a stranger, but on special occasions, donation of blood is required for members of the family, friends, mutual connections or other such acquaintances.

While the process is not time consuming there are certain precautions and points that one should follow before and after donation of blood. These include not consuming aspirin or any such medicine or drug at least 48 hours before donating blood, high consumption of products rich in calcium and iron, resting for a few hours later as one might feel weakness, dizziness, etc. Specific instructions are given to every donor before and after the blood donation. Liquid intake should be high after donation of blood.

Blood donation is done through fresh and sterile needles in hygienic conditions so that utmost care is maintained. While blood on whole can be donated, possibilities also exist for donation of simply platelets instead of the whole blood. The difference is that the process of donating platelets is more time consuming than the process of donating blood.

Neither of the process produces much pain to the donor after a momentary sting. A person is eligible to donate blood once in every three months, given their level of haemoglobin is moderate as per required. Distinctively, a person can donate platelets up to twenty four times in an year. Donation of platelets can be done after seventy two hours of donation of blood by a person.

3.Why are platelets important?

Platelets are absolutely significant in the bodily processes of clotting the blood and sealing a wound by creating a barrier that prevents excess blood flow. Through platelets, millions of patients and people around the globe are able to fight life-threatening diseases like cancer, diseases that are chronic, trauma-inducing diseases, wounds and cuts, etc. Furthermore, they are specifically important for patients undergoing blood diseases, skin cancer, bone marrow cancer, etc. Even during the medical process of transplants, platelets play an active role.

Around the globe, one in thirty patients are in dire need of platelets, according to various medical surveys. Platelet donations become stagnant after five days of collection and hence are used quickly to ensure the best possible outcome.

4.Replacing of blood cells after donations

Through automatic processes, blood cells are produced by the bone marrow and these get replaced in lakhs and crores post every donation. Red blood cells are easily replaceable in the body. Hence, blood donation actually helps the donor also by replacing old cells with new, fresh cells. Therefore, one should not feel a setback in their life due to donation of blood.

5.Decrease in platelets after donation

If a person experiences decrease in platelets after donating whole blood or platelets, then it is possible that the person has contacted the condition called immune thrombocytopenia (ITP). In this condition, the immune system of the individual gets weakened and they face the following symptoms:

●Easy bruising
●Bleeding (from gums, mouth, nosebleeds, other body parts)
●Skin rash
●Red, flat spots on the skin
●Bruises in the form of blotches lying under the skin
