Additional Information

Antibody Identification studies include a 10 cell panel. If additional red cell panels are required for identification, this testing will be performed at an additional charge. If antigen determination is indicated Human Erythrocyte Antigen Genotyping will be performed at an additional charge. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
