Key facts
- MICA*042 IgG Ab [Presence] in Serum
- MICA*042 Ab.IgG
- IgG antibodies to MICA antigens, including MICA*042, can be detected in the serum of people during pregnancy, blood product transfusion, or unsuccessful organ transplants. MICA antibody testing identifies antibodies against a panel of MICA antigens by methods such as flow cytometry. MICA antibody testing using serum can be done pre and post transplantation. A positive result is an indication of sensitization to MICA antigens. This term is based on, but not exclusive to, the submitter's test kit, LIFECODES LSA(TM)-MIC, a Luminex® screening assay for the qualitative detection of anti-MICA IgG antibodies.
