The Rh factor is also known as the Rhesus factor. It is named from the Karl Landsteiner and Alexander S. Weiner experiments in 1937. There are types of blood: A, B, O, and AB. Every type is also identified as positive or negative. This negative and positive label is used as a reference to the Rhesus factor of the blood. Rh positive have the Antigen present in their blood, while a Rh negative person does not have the Antigens. If a person has a blood type of A and has the Rhesus factor they are considered to be A-positive, or A+, blood. If people are missing the antigen, they are Rh-. I am B negative and I have a twin who is B positive. She has the antigens and I don’t.
“More than 85% of people are Rh-positive. People without the Rhesus factor, that is, people that don't have the antigen in their blood, are Rh-negative.”
