The best way to prevent hemolytic disease of the fetus and newborn (HDFN) is to give a pregnant woman an injection of RhIG (Rh immune globulin) during pregnancy and shortly after the birth of her baby. RhIG is a medication that contains large amounts of "D antibody." The D antibody removes any of the baby's Rh positive red blood cells from the mother's bloodstream. This will not harm the woman or the baby.

What causes protein C deficiency?
Michael Roizen, MD, Internal Medicine, answeredAbout one in 300 people have a mild deficiency of protein C, a blood chemical that helps prevent clotting. People who don't have enough protein C are more vulnerable to deep vein thrombosis (DVT), a clot in a deep vein that can be life-threatening if it causes a stroke or goes to the lungs.
A genetic mutation causes this deficiency, and it's usually inherited. When a family member is diagnosed with protein C deficiency, other family members can be tested for the mutation (it's in the PROC gene). They should also be tested for clotting speed and protein C levels.
The outlook for people with mild protein C deficiency is good. If they do have a DVT, they'll need to go on blood-thinning drugs for a few months and be cautious about anything that increases the risk of clots (like sitting still for long periods of time).
Can blood flow affect formation of blood clots?
Mehmet Oz, MD, Cardiology, answeredVery slow blood flow, such as because of inactivity, can make you more likely to form blood clots. Watch this animation to see how slower blood flow affects the formation of blood clots.
