What If Your and Your Baby’s Rh Factor Is Different?

What If Your and Your Baby’s Rh Factor Is Different?

If mother and baby have different Rh factor such as one has Rh -ve blood and other has Rh +ve blood, it could be the root cause of medical conditions for mother or baby. Here are answers to your queries regarding Rh factor and Rh incompatibility. Learn more about the significance of Rh factor during pregnancy.

What is Rh-ve blood?

Every human blood is either Rh +ve or Rh –ve.  Rh+ve means there is certain amount of protein present on the surface of red blood cells and Rh -ve means protein doesn’t exists.

Who is at a risk for Rh Incompatibility?

If mother is Rh -ve and father is Rh +ve or Rh-unknown or vice-versa, the baby is at risk for Rh incompatibility. Body takes time to develop antibodies; therefore firstborn baby is usually not affected. However, if mother has previously undergone a miscarriage or abortion or Rh +ve blood transfusion, then even the first baby is at risk of Rh incompatibility.

How Rh incompatibility can be diagnosed?

A prenatal blood test is done to know whether you’re Rh -ve or Rh +ve. If you are Rh -ve, then at about 10 weeks of your pregnancy you’ll have an Indirect Coombs Test (ICT) and a follow-up ICT at 28 weeks, which checks that your body is making Rh antibodies or not.

How Rh incompatibility is treated?

Treatment focuses on preventing the problems due to incompatibility.

  • In mild cases, the baby is treated after birth with blood transfusions, electrolytes, hydrating fluids or phototherapy. Repeatedness of these processes depends on the infant’s condition.
  • If during pregnancy your body start developing antibodies against your unborn, your pregnancy must be closely monitored. In rare cases, special blood transfusions are performed with unborn or born baby.
  • The consequences of Rh incompatibility can be checked by giving an injection of Rh immune globulins (RhIg) to mother at 28 weeks if ICT is –ve at 28 week. This contains antibodies to the Rh factor. The mother again gets a second injection after delivery if baby is Rh +ve.
