What is it?

Rh factor is a protein on red blood cells. Rh incompatibility is when a mother has Rh-negative blood and her baby has Rh-positive blood. Rh isoimmunization is when the blood from the baby makes the mother's body create antibodies that can harm the baby's blood cells.

Hemolytic Disease due to Rh Isoimmunization.

Signs & symptoms

Symptoms will only be in the baby. They can be mild to severe, such as:
* Anemia- red blood cells are destroyed faster than they are made
* Jaundice- a buildup of a substance in the blood that causes the skin to look yellow
* Swelling of the body, which can lead to heart failure or breathing problems.


A woman's Rh factor is tested at routine visits. Blood tests will be done to:
* Find out if the mother is Rh positive or Rh negative
* Look for Rh antibodies
* Keep track of antibody levels
An amniocentesis may also be done. It removes and tests a small amount of the fluid that surrounds the baby to find out if the baby is Rh positive.


The goal of treatment is to keep the baby healthy and lower the risk of this problem in future pregnancies.
Rh incompatibility will be treated by giving the mother Rh immune globulin to prevent Rh isoimmunization.
Not all babies will need to be treated. Those who do may need:
* Medicine to help the body make red blood cells
* A transfusion to replace blood cells that are being destroyed
* To be delivered early
