Pregnancy

Blood group and Rh test

Also called blood type, ABO, Rh factor

Your ABO group and whether you are Rh positive or negative.

Why it's done

Needed early in pregnancy and before any transfusion or surgery.

What a low result can mean

If you are Rh negative and the baby's father is Rh positive, you may need an anti-D injection around 28 weeks and after delivery.
