Humans with this antigen require special treatment during pregnancy and blood transfusion.

Identification Rh factor is identified through a simple blood test. Rh proteins discovered in the blood indicate an Rh-positive blood type. Lack of Rh proteins suggests an Rh-negative blood type. Statistics Palomar College of California’s website states that only one in 1,000 Rh-negative babies are born annually in the United States. Rh-negative blood type is most prevalent in European countries; 13 percent of all European babies are Rh negative
