Clinical Significance
Hemoloysis or agglutination in the antibody screen indicates the presence of atypical antibodies. The clinical significance of these antibodies must be ascertained through the further evaluation of antibody identification panels, auto controls and compatibility testing. These must be done prior to release of blood for transfusion. No hemolysis or agglutination indicates the patient's plasma or serum is free of commonly encountered, clinically significant antibodies.
