Some medications may be cause for deferral but many are acceptable, including blood pressure medications, cholesterol lowering medication and diabetic medication among many others. The good news is that there is no longer an upper age limit for blood donation. It is not possible to contract HIV, the virus that causes AIDS, or any disease when donating blood. All of the equipment used for blood donation is new, sterile and is disposed of immediately after a single use. There are many places where donations can be made.
Bloodmobiles travel to high schools, colleges, churches, and other community organizations.
Many people donate at blood drives at their workplace. Although most blood is donated as whole blood, it is also possible to donate only a portion of blood using a technique called apheresis. Blood is drawn from the vein of a donor into an apheresis instrument, which separates the blood into different portions by centrifugation. By appropriately adjusting the instrument, a selected portion of the blood, such as the platelets, can be recovered, while the rest of the blood is returned to the donor either into the same vein or into a vein in the other arm. This process takes more time than whole blood donation, but the yield of platelets is much greater.
