Version 2.78

Description

The first antibody in the Knops blood group was found in the serum of an O Rh negative woman who had been multiply transfused in previous surgeries. Her blood was incompatible with all O negative donor units tested until the blood bank technologist Margaret Helgeson, tested her own blood and found it compatible. Thus, in a report published in 1970, the antibody was named anti-Kna-Helgeson and the blood group called Knops. The Helgeson cells were used extensively to test other antibodies with previously unknown specificities. In 1978, another antibody was identified that was compatible with the Helgeson cells but not the Knops-negative cells and this was named McCoy (McCa). The next antibody reported for the system was named after the first two antibody producers, ie. Swain and Langley, thus the designation Sla. The final antibody identified to a high frequency antigen in the Knops system was found in the serum of Mrs. York and was named Yka. Source: Serum, Cells and Rare Fluid Exchange, SCARF
