What Rh Factor? Why is it important?

Explanation:

The Rh factor is one of the proteins on RBCs used to indicate whether the blood of two different people is compatible when mixed – such as blood of a mother and her baby at birth.

It is routine and important that the Rh factor for a mother and unborn child be determined during pregnancy.
