We all know that there are four primary human blood types. They are known as A, B, AB, and O. Those blood types are categorized according to the antigens in the blood. This means if you are an A blood type, you own A antigens.

If you are a B blood type then you own B antigens. If you own both then you are an AB blood type. However, you are an O blood type when you own neither A nor B antigens. If you are an O blood type or have someone special with an O blood type, this article is meant for you.

Someone with an O blood type but without Rh factor would be an O negative blood type which is also believed as a universal donor. It is called universal donor blood because this blood type can be accepted literally by anyone.

Here are some personality traits of O negative blood type which is mostly conserved as a special or one-of-a-kind personality:
