This test is only for University of Michigan Health System patients wearing an identification wristband. Collect specimen in a pink top tube. The phlebotomist must sign the requisition and must initial and date the specimen tube. Refrigerate and send intact specimens. 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.
If the Antibody Screen is positive, Antibody Identification 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.
