Know Your Type: AB-

Understanding Your Blood Type

AB- is one of the most uncommon blood types. AB- individuals are also unique in that they are universal plasma donors! Because AB affects so few people, your plasma is always in demand!


Best Use of Your Blood Type

The best way to use your powerful lifesaving donation is by donating:

  • Platelets

    Can be donated every 7 days up to 24 times a year and have a shelf life of only 5 days. Platelets are usually given to cancer patients because chemotherapy prevents them from being able to produce them on their own.

  • Plasma

    Can be donated every 28 days. Plasma donations take 45 minutes to 1.5 hours once connected. Plasma is often used for burn victims, traumas, and during transplants.
