title: Comparison of a manual hexadimethrine bromide-antiglobulin test with saline- and albumin-antiglobulin tests for pretransfusion testing.
abstract: A prospective double-blind study compared a manual hexadimethrine bromide (Polybrene) antiglobulin antibody detection test (P-AHG) and crossmatch with the albumin-antiglobulin antibody detection test and saline-antiglobulin crossmatch routinely used in our laboratory. A total of 10,084 pretransfusion blood samples from approximately 6000 patients were tested. The P-AHG method detected 153 of 157 alloantibodies for which antigen-negative, crossmatch-compatible blood is routinely provided. All four antibodies not detected were anti-K. The routine techniques detected 147 of the 157 alloantibodies. The P-AHG method detected only 36 percent of the alloantibodies for which crossmatch-compatible blood is routinely provided without determination of the antigen status of the donor unit's red cells (e.g., anti-Lea), whereas the routine method detected 91 percent of such antibodies. Eighty-six percent of the 189 alloantibodies detected by the Polybrene technique were found before the addition of antiglobulin. The manual Polybrene test is a rapid and sensitive technique; it may be used without an antiglobulin phase as a routine crossmatch procedure when accompanied by a sensitive antibody detection test that includes antiglobulin and an additional test to ensure ABO compatibility.
