Further evidence of heterogeneity within the Kidd blood group system.
Serological studies on blood of selected individuals show that red blood cells from individuals genetically JkaJk and JkbJk give single dose agglutination reactions with anti-Jka and anti-Jkb respectively, but react as strongly with anti-JkaJkb as do cells from random individuals. A Jk(a+b-) Oriental person has been found whose red blood cells give a single dose reaction with anti-Jka, but react more weakly than do cells from random people in tests with anti-JkaJkb. The results support a conclusion that the antigen recognized by anti-JkaJkb is a distinct and separate antigen of the Kidd blood group system.
