Test Overview
To detect IgG immunoglobulin and/or complement adherence to red cells, as seen in immune hemolytic anemia or in a delayed hemolytic transfusion reaction. Positive tests will be further evaluated for bound and unbound antibody specificities associated with Cold Hemagglutinin Disease, Warm Autoimmune Hemolytic Anemia, and delayed reaction to transfusion. Positive tests will be further evaluated to determine the specific type(s) of protein adhering to the red cells and present in the serum (indirect test).
Negative
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Specimen Requirements
Collect specimens in two pink top tubes. Send intact specimens at room temperature. Specimens are unacceptable if collected in serum separator tube, contaminated, or grossly hemolyzed. Specimens sent for Blood Bank testing cannot be split for use by other laboratories.
