Short Answer
The Rh factor is a protein (Rh D antigen) found on the surface of red blood cells that determines whether your blood type is positive or negative.
Detailed Explanation
If your red blood cells carry the Rh D antigen, you are Rh-positive (+).
If the antigen is absent, you are Rh-negative (−).
The Rh factor is important because incompatible Rh blood transfusions can cause serious immune reactions. It is also important during pregnancy, where Rh incompatibility between mother and baby may require medical management.
Key Points
- Rh factor is separate from the ABO blood group.
- People are either Rh-positive or Rh-negative.
- Rh compatibility is essential for transfusions.
- Rh factor is important during pregnancy.
