A test to determine whether a woman has Rh-positive or Rh-negative blood (Rh antibody titer) is done early in pregnancy. The Rhesus factor is important during pregnancy and causes problems when an Rh–negative person’s blood comes in contact with Rh–positive blood.
Rh antibody titer test determines the type and quantity of antibodies in the blood. Rh antibodies are likely to rise during pregnancy. Depending on the level of other antibodies these antibodies could cause hemolytic problems in the baby and need to be monitored.
Normal Values for Rh Antibodies Titre is > 1:16.
