Blood comes in different types. Each person has a specific ABO type (A, B, AB, O) and Rh factor (positive or negative).
The most prevalent types of blood are O positive and A positive. The least common types are B negative and AB negative. Only fifteen percent of the population is negative for the Rh factor.
