Any adult who is physically and mentally healthy can donate blood. 450 millilitres of blood are usually taken during blood donation. This amount of blood components is replenished within three months. So a healthy person can donate blood many times in life.
Blood donation capacity is determined according to the Bangladesh Government Gazette. Each blood donation center has a specific form to verify blood donation capacity, which is filled out by the blood donor himself. Then some tests are done to determine the suitability of blood donation.
Those who cannot donate blood
- Age below 18 years or above 60 years
