Solid-phase antiglobulin test for screening and identification of red cell antibodies.

A newly developed automatically readable solid-phase antiglobulin test is described. The solid-phase test in comparison with conventional antiglobulin techniques for screening and identification of red cell antibodies showed agreement in 2346 (98.7%) of samples tested. The increased sensitivity of the solid-phase antiglobulin test is demonstrated by examination of serial twofold dilutions of antibodies.
