The UCLA International Cell Exchange sends test samples to 200 laboratories around the world to assess the accuracy of HLA (Human Leukocyte Antigen) class I and class II typing and of KIR (Killer-cell Immunologulin-like Receptors) typing. Results by serologic and DNA methods are evaluated for class I and class II. Each laboratory can compare its results with those from other participating laboratories.
The Cell Exchange also provides human sera containing HLA-specific antibodies with the goal of evaluating laboratories' abilities to detect and identify the antibodies.
The UCLA International DNA Exchange provides 6 specimens of purified DNA 6 times each year to participating laboratories to compare results of DNA-based HLA-typing methods. The results of each exchange are graded and participants receive a summary of their performance in each exchange and a complete summary of results from other participating laboratories.
