If the Rh factor protein is present on the cells, the person is Rh positive. If there is no Rh factor protein, the person is Rh negative.

Hello friend,
In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent ( – ). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.
The universal red cell donor has Type O negative blood type.
The universal plasma donor has Type AB blood type.
hope it helps you
