If you have Rh-negative blood, injections of Rh immune globulin can reduce your risk of Rh incompatibility in future pregnancies. It's important to get this medicine every time you give birth to an Rh-positive baby or come in contact with Rh-positive blood.
If you're Rh-negative, your risk of problems from Rh incompatibility is higher if you were exposed to Rh-positive blood before your current pregnancy. This may have happened during:
You also can be exposed to Rh-positive blood during certain tests, such as amniocentesis and chorionic villus sampling. (For more information, go to "Who Is At Risk for Rh Incompatibility?")
Unless you were treated with Rh immune globulin after each of these events, you're at risk for Rh incompatibility during current and future pregnancies.
Let your doctor know about your risk early in your pregnancy. This allows him or her to carefully monitor your pregnancy and promptly treat any problems that arise.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans.

New NHLBI Program Trains Scientists to Bring More Science Out of the Lab and into the Patient Care Marketplace
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
