Description

ABO testing is performed to determine if patient has blood group of A, B, O or AB. Rh testing is performed to determine if patient is Rh(D) Positive or Rh(D) Negative. Both ABO and Rh testing establishes the blood type of the patient.

Antibody Screen testing is performed to detect clinically significant antibodies to RBC antigens, which are defined as those that have been previously associated with hemolytic disease of the fetus and newborn, hemolytic transfusion reactions or decreased RBC survival. Typically, these antibodies react at 370C or AHG phase.

Both ABO/Rh and Antibody Screen may be performed on automated analyzer or standard tube method.
