Register Become a blood donor. Who can give blood? Most people can give blood if they're fit and healthy. This needle is attached to a thin, plastic tube and a blood bag. Once the needle is in place, you tighten your fist several times to help the blood flow from the vein. Blood initially is collected into tubes for testing. When these have been collected, blood is allowed to fill the bag, about a pint about half a liter.
The needle is usually in place about 10 minutes. When complete, the needle is removed, a small bandage is placed on the needle site and a dressing is wrapped around your arm. Another method of donating blood becoming increasingly common is apheresis.
During apheresis, you are hooked up to a machine that can collect and separate blood components, such as red cells, plasma and platelets. This process allows more of a single component to be collected. It takes longer than standard blood donation — typically up to two hours. After donating, you sit in an observation area, where you rest and eat a light snack. After 15 minutes, you can leave. After your blood donation:.
Your blood will be tested to determine your blood type and your Rh factor. The Rh factor refers to the presence or absence of a specific antigen — a substance capable of stimulating an immune response — in the blood. You'll be classified as Rh positive or Rh negative, meaning you do or don't carry the antigen.
This information is important because your blood type and Rh factor must be compatible with the blood type and Rh factor of the person receiving your blood. Your blood will also be tested for bloodborne diseases, such as hepatitis and HIV.
If these tests are negative, the blood is distributed for use in hospitals and clinics. If any of these tests are positive, the donor center notifies you, and your blood is discarded. Explore Mayo Clinic studies of tests and procedures to help prevent, detect, treat or manage conditions.

There's an important link between your red cells and your health because it's these cells, or rather the red-coloured haemoglobin they contain, that take oxygen around your body. Haemoglobin contains iron, and some is lost with each blood donation. To compensate, iron is mobilised from the body's iron stores, and the body also increases the amount of iron it absorbs from food and drink.
Men normally have more iron stores than women. Before every blood donation we always test your haemoglobin levels. This is because any iron deficiency can result in reduced haemoglobin levels, and eventually, if not treated, in iron deficiency anaemia. This deficiency can make you feel tired. The proteins are found in the liver, bone marrow, spleen and muscles. If too much iron is taken out of storage and not replaced through dietary sources, iron stores may become depleted and haemoglobin levels fall.
After a donation, most people's haemoglobin levels are back to normal after 6 to 12 weeks. So, although you donate less than a pint of blood at a time, almost half of this is water. That's why it is important for you to drink plenty of water before you donate and immediately after you've donated. It's important to replace fluids after you've donated, to help bring your blood volume levels back to normal.
