Type and Screen

Blood Group, Blood Type, Antibody Screen

ABO/Rh determines the blood group (ABO) and Rh type (pos or neg). ABS detects antibodies directed against red blood cell antigens. The Blood group, Rh type, and Antibody Screen of expectant mothers may indicate potential for hemolytic disease of the fetus/newborn. Rh typing is used to determine Rh immune globulin candidacy for prenatal and postpartum patients.
