Background Information for HLA Antibody Screen, Class I and Class II Purpose: To detect HLA Class I and Class II IgG antibodies. Analytical Sensitivity & Specificity: More sensitive than traditional lymphocyte cytotoxicity procedures. Limitations: Only detects IgG antibody isotype; IgM antibodies are not detected. This test does not provide information on the specificities of the HLA antibodies detected. Test Results: Results are reported as positive or negative for HLA Class I and Class II antibodies. This test was developed and its performance characteristics determined by the H&I laboratory at the University of Utah Health under the accreditation guidelines from the American Society for Histocompatibility and Immunogenetics (ASHI). Some tests or reagents have not been cleared or approved by the FDA.
