Test Description
Donor ID, Major and Minor Cross Match
Screens for pre‑existing antibodies directed against red cell antigens to determine serological compatibility prior to transfusion. If serum, as well as whole blood, is submitted both minor and major cross‑match will be performed. This test is not intended for use in determining pre‑breeding compatibility testing, neonatal isoerythrolysis, or the prevention of neonatal isoerythrolysis.
Interferences: Marked hemolysis and lipemia.
Note: This test must be used in addition to Cross Match (T340).
