Rh Factor in Pregnancy
Robin Elise Weiss in About.com reports:
We don’t often give much thought to the blood work of early pregnancy. Many of us never hear another word about those droplets given in the early weeks. However, one of the tests performed with this blood is a blood type and factor screening.
In addition to the blood group (A, B, O, AB), the Rh factor is written as either positive (present) or negative (absent). Most people are Rh positive. This factor does not effect your health except during pregnancy.
