Useful For
Assessing positive pretransfusion antibody screens, transfusion reactions, hemolytic disease of the newborn, and autoimmune hemolytic anemias

Testing Algorithm
The following tests may be ordered and performed as needed for antibody identification: direct antiglobulin testing (polyspecific), including its reflex tests and special red cell antigen typing. Additional reflex charges will be added as needed for antibody elution, antibody adsorption, antibody panels, and special red cell antigen typings.
If certain antibodies are detected and the patient is known to be pregnant, an antibody titration will be performed at an additional charge.
