NHS Blood and Transplant is asking for men between the ages of 18 and 65 to consider donating their blood plasma. Plasma is used to make antibody-based medicines called immunoglobulins, for people with weak immune systems and a variety of other rare disorders. Thousands of patients rely on immunoglobulin medicines for short-term treatment or lifelong diseases.
Men are more likely to have the blood plasma volumes and larger vein sizes making them ideal donors. Donating plasma takes about 45 minutes and is completely safe. During the process the plasma is filtered out of circulating blood by an apheresis machine and the red blood cells are returned to the donor. It is possible to donate as often as every two weeks, with a maximum of 24 donations per year.
