Blood Donation


Blood Donation Summary

Donating blood is safe and simple. It takes approximately 10-15 minutes to complete the blood donation process. Any healthy adult between 18 years and 60 years of age can donate blood. This is what you can expect when you are ready to donate blood:

  • You walk into a reputed and safe blood donation centre or a mobile camp organized by a reputed institution.

  • A few questions will be asked to determine your health status (general questions on health, donation history etc). Usually you will be asked to fill out a short form.

  • Then a quick physical check will be done to check temperature, blood pressure, pulse and haemoglobin content in blood to ensure you are a healthy donor.

  • If found fit to donate, then you will be asked to lie down on a resting chair or a bed. Your arm will be thoroughly cleaned. Then using sterile equipments blood will be collected in a special plastic bag. Approximately 350ml of blood will be collected in one donation. Those who weigh more than 60 Kg can donate 450 ml of blood.

  • Then you must rest and relax for a few minutes with a light snack and something refreshing to drink. Some snacks and juice will be provided.

  • Blood will be separated into components within eight hours of donation

  • The blood will then be taken to the laboratory for testing.

  • Once found safe, it will be kept in special storage and released when required.

  • The blood is now ready to be taken to the hospital, to save lives.

Some Myths Clarified

Blood donation requires external motivation - most people are easily misled by misconceptions and hesitate to donate blood. Some are scared at the thought of a needle poking their vein to collect blood. Some others feel faint at the sight of blood.

Here is some scientific evidence that will clarify most misconceptions.

Will I become weak and anaemic after donating blood?

Donating blood is unlikely to make a person weak or anaemic. If the person is already anaemic, then the person will not be allowed to donate blood.

What happens to the blood I lose? Will I get it back?

Blood usually recuperates within 48 hours after blood donation. Usually not more than 350 ml of blood is collected in one donation. This is roughly <7% of the total blood volume in an average healthy person, who has approximately 5 litres of blood.

Will I get any disease when I donate?

NEVER. Reputed donation centers and blood banks usually use sterile single use bags and needles and have trained staff to handle the process. There is no risk of catching any disease in the process of donating blood.

Will my BP go down after donating blood?

Some people are anxious during blood donation and their anxiety shows up as a slightly elevated pulse rate. Usually this settles down after in a few minutes. Blood donation does not usually affect blood pressure.

Will I feel giddy after donation?

Unlikely. The feeling of giddiness is more psychological than physiological. There is no need to be anxious about blood donation. It is safe, easy and painless.

Will I lose my red cells in the blood if I donate frequently?

No. A person can safely donate blood every 90 days. Donating at regular intervals does not result in loss of hemoglobin or red cells.
