Introduction to the Rhesus Blood Group


The Rh blood group system is one of the largest and most polymorphic. This presentation describes several Rh antigens and antibodies of clinical significance, Weak D phenotypes, and rare phenotypes that result from deletions and gene mutations. In addition, different nomenclature systems are explained.

Originally presented on December 16, 2015 in Salt Lake City, Utah.
