Vitalant – What are the Different Blood Types | Vitalant

You’re an AB blood type — either AB-positive (AB+) or AB-negative (AB-). But what exactly does that mean for you and the patients who can receive your blood? Let’s explore some AB blood type facts.

The AB-negative blood type is the rarest one in the United States. Only 1%, or 1 in every 100, Americans have this blood type. AB-positive is also one of the rarer blood types, coursing through the veins of only 4% of the U.S. blood donor population, or 1 in every 25 people.

Blood type AB is spread pretty evenly among all races and ethnicities. Asian Americans are slightly more likely to have AB blood type than other ethnicities, according to the ADRP.
