some info for those with G6PD deficiency .........
http://enews.donorweb.org/2006/02/16/donors-voices/Q. When I was informed that I have G6PD deficiency, I was told that I couldnÂ’t donate blood. Is it true?
A. G6PD deficiency is a genetic blood disorder. It is an inherited condition that affects the bodyÂ’s red blood cells.
The great majority of people with G6PD deficiency are healthy and do not experience any symptoms clinically. As such, they are still allowed to make blood donations. However we usually would advise donors with G6PD deficiency to donate plasma or platelets via apheresis technique instead of whole blood. RBC donations are not recommended as their bone marrow is already working hard to compensate for their condition and we do not want to further exhaust their marrow. The red blood cells of those with G6PD deficiency are also more fragile. These red blood cells have a shorter lifespan and hence would not be suitable for transfusion to anaemic patients.
Apheresis is a specialized form of blood donation in which only plasma or platelets are extracted from the donor. The donorÂ’s RBCs are filtered off simultaneously and returned to the donorÂ’s circulation. The donorÂ’s weight must be 51 kg or more to qualify for apheresis donation. The cubital veins must also be sufficiently large to allow adequate venous access. In addition, donors must have a minimum hemoglobin level of 13 g/dl before they can give blood and a minimum hemoglobin level of 12.5 g/dl before they can make an apheresis donation. This will be tested prior to any donation.
