Rh
Positive or negative
Rh is the Rh factor, a protein on red blood cells that determines blood type compatibility.
Blood is classified as Rh-positive or Rh-negative depending on whether this protein is present.
The designation matters most in blood transfusions and pregnancy, where Rh incompatibility between mother and fetus can cause complications.
Named for the rhesus monkey, in which it was first identified.
