Rh Factor Incompatibility

WHAT YOU SHOULD KNOW:

Rh (rhesus) factor incompatibility is a condition that occurs when a mother is Rh negative (Rh-) and her baby is Rh positive (Rh+). Rh factor is a protein found on red blood cells. You are Rh+ if you have this protein and Rh- if you do not have it. Rh incompatibility usually has little effect on your first pregnancy, but can cause problems with future pregnancies.

AFTER YOU LEAVE:

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Prevent Rh factor incompatibility:

Immune globulin (RhIg) shots may help reduce your risk. These shots prevent your body from making Rh antibodies. RhIg shots are usually given in the 28th week of pregnancy and within 72 hours after giving birth. You may need another shot if you have not given birth within 12 weeks after the first shot. RhIg shots may also be given after an abortion, miscarriage, or abdominal trauma. Shots are also given after any procedure that may cause your baby's blood to leak into your bloodstream. These procedures may include amniocentesis, fetal blood sampling, or a change in the baby's position in the womb before birth.
