Anti-Kp^b

Kp^a (KEL3), Kp^b (KEL4) and Kp^c (KEL21) are part of the Kell system (ISBT, number 006). Kpa is present in approximately 2% of the Caucasian population while Kpb is a high frequency (public) antigen. The Kp^c antigen has an occurrence of less than 0.01% but up to 0.32% in Japanese. Anti-Kp^a and anti-Kp^b are less common than anti-K but have similar serological characteristics and are considered to be clinically significant. They may occur after transfusion or by feto-maternal immunization.
