HLA Class I Antibody Identification
Also known as: HLA Class 1 Antibody, White Cell Antibody
Use
Solid organ transplantation
Special Instructions
Not provided.
Limitations
The test is designed to detect antibodies of the IgG isotype but does not detect IgM antibodies, which are usually indicative of autoantibodies. Therefore, the absence of IgG detection in this test does not preclude the presence of autoantibodies. This limitation should be considered when interpreting test results, especially in complex immunological assessments relating to autoimmune conditions or other clinical scenarios.
