Is it possible that an Rh negative blood be compatible with an Rh positive in a crossmatching procedure?

In crossmatching you don't actually mix the whole blood samples. You will mix the red blood cells of the donor with the plasma of the patient. So if the patient is Rhesus positive, it wont have antibodies in the plasma against the Rhesus factor on the red blood cells of the donor. So a crossmatch with either a negative or positive donor will be allright. So in this case, it is indeed possible.

No. O negative is the universal donor.


is A positive blood a universal donor type?

O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
