Abstract
Rh antibody hybrids for use in testing red blood cells for the presence of one or more Rh factors. The Rh hybrid antibody may also be used in therapeutic procedures which require the use of Rh antisera. The hybrid antibody includes an IgG anti-Rh antibody which has a polymeric tailpiece attached to the carboxy terminal end of each of the IgG antibody heavy chains. A hemagglutinin method is provided for Rh phenotyping in which agglutination of Rh-positive red blood cells is achieved in a one-step process involving addition of the hybrid Rh antisera to the red blood cells being tested.
