RH( RHESUS) ANTIBODY TITRE TEST

The Rh (Rhesus) Antibody Titre is a blood test that is primarily used during pregnancy to determine the mother's Rh blood type (Rh positive or Rh negative) and to check whether she has developed antibodies against the Rh antigen. The Rh antigen is a protein found on the red blood cells (RBCs) of about 85% of people, and they are termed Rh positive. Those who lack the Rh antigen are referred to as Rh-negative. This is particularly important in cases where an Rh-negative woman is pregnant with an Rh-positive fetus. The immune system of the Rh-negative mother may recognize the Rh antigen on the fetal blood cells as foreign and produce antibodies against it, a process known as Rh sensitization. The Rh Antibody Titre test measures the levels of these antibodies in the mother's blood.
