What is your Rh factor?

ANSWER

The Rh factor is a protein in the blood. If you have it, you’re Rh-positive. If you don’t, you’re Rh-negative. Most people are Rh-positive. Parents pass along their Rh-factor status to their babies. Your doctor needs to know your Rh status because your baby can develop a serious health problem if she’s Rh-positive and you’re Rh-negative. This is called Rh incompatibility.
