What is the Rh-factor?
उत्तर
The Rh-factor was first discovered in the Rhesus monkey. It was found that Rh (rhesus) antigens were causing many of the transfusion failures that were unexplained by the A-B-O system. There are at least eight different Rh antigens so far. The person bearing Rh-factor is Rh+ve and a person who does not possess this factor is Rh-ve.
