The antibody titer is a test that detects the presence and measures the amount of antibodies within a person's blood. The amount and diversity of antibodiescorrelates to the strength of the body's immune response. The indirect Coombs test is commonly done to find antibodies in a recipient's or donor's blood before a transfusion. A test to determine whether a woman has Rh-positive or Rh-negative blood (Rh antibody titer) is done early in pregnancy. If she is Rh-negative, steps can be taken to protect the baby. ELISA is a common means of determining antibody titers. For example, the indirect Coombs test detects the presence of anti-Rh antibodies in a pregnant woman's blood serum. A patient might be reported to have an "indirect Coombs titer" of 16.
No special preparation is needed for Rh Antibodies Titre. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Rh Antibodies Titre. Your doctor depending on your condition will give specific instructions.
