A listing of 20 kinds of null RBC types has been made1 of which the most striking is the total Rhnull.Ten years ago a hemolytic anemia was reported in an Rhnull proposita living in Virginia.2Hemolytic anemia has now been proved in all Rhnull propositi and has been described as well for nulls in other blood group systems.
