O Positive

Your blood type is very important because it can potentially be transfused to any patient with a positive blood type. O positive blood is also very common, so more people with your type are in need of transfusions.

The best donation for your blood type is double red cells.* By donating double red cells, you can give two units of these potentially lifesaving cells at one time. Double red cell donation is a special automated process.

Automation allows you to donate certain components of your blood in larger amounts. During an automated donation, your blood is drawn into a machine which separates the needed component from the rest of the blood. The final component is collected in a donation bag, while the rest of the blood is returned to you.

To schedule your double red cell donation, call 1-800-GIVE-LIFE.
