RH factor is a protein that may be present on red blood cells.
A person is either:
- RH-positive
- RH-negative
RH factor can become important during pregnancy if the mother and developing baby have different blood types.
Why RH Factor Matters During Pregnancy
If an RH-negative mother is carrying an RH-positive baby, the body may produce antibodies that affect future pregnancies.
Healthcare providers may recommend an injection called Rh immunoglobulin to help prevent complications.
