What is the significance of Rh antibody titer in Lab based Blood typing?
Rh antibody titer test determines the type and quantity of antibodies in the blood. Rh antibodies are likely to rise during the pregnancy and depending on the level of other antibodies (e.g. anti-Kell) these antibodies could cause hemolytic problems in the baby and need to be monitored. It is usually repeated several times during pregnancy (at 32, 36, & 38 weeks). A low titer (no higher than 1:16) may not pose any problem for the baby. In any test higher than 1:64, an intrauterine exchange transfusion may be suggested.
