Type AB blood is rare – it's found in less than five percent of the population. And it is the newest of the blood types. Until ten or twelve centuries ago, there was no Type AB blood type. Type AB resulted from the intermingling of Type A with Type B. Type AB is the only blood type whose existence is the result of intermingling rather than environment. Thus, they share both the benefits and the challenges of both Type A and Type B blood types. Type AB has a unique chameleon like quality – depending on the circumstances, this blood type can appropriate the characteristics of each of the other blood types. Type AB is sometimes A-like, sometimes B-like and sometimes a fusion of both. Today, as we look back at this remarkable evolutionary revolution, it is clear that the genetic characteristics of our ancestors live in our blood today.

Freedom-loving AB's are strong and rational people. They don't worry about little things and usually can assess their life challenges without emotions getting in the way. Despite their love for freedom and independent thinking they don't have any issues when it comes to relationships and are quite popular.

Type AB often receives mixed messages about emotional health. While you tend to be drawn to other people and are friendly and trusting, there is a side of you that feels alienated from the larger community. At your best, you are intuitive and spiritual, with an ability to look beyond the rigid confines of society. You are passionate in your beliefs, but you also want to be liked by others and this can create conflicts. In an independent study, Type ABs described themselves as emotional, passionate, friendly, trusting and empathetic.
