In brief: Blood group antigen

Rhesus (rh) blood group is one of the more than 20 different blood group systems.
One of the markers in rh system is "d" that is used in the terminology you inquired about. If rh d is present the person is rh positive and vice versa. See this site for more info (more than one needs) http://www.Ncbi.Nlm.Nih.Gov/books/nbk2269/.
