In brief: Blood cell antibody
If your blood type is a negative, that means your red blood cells lack the rh antigen (protein), if you are exposed to rh positive cells in a blood transfusion or in pregnancy, the rh antigen is foreign to you and your cells attack it with antibodies.
The screen looks for these and other antibodies that could be harmful to a developing fetus.
