Embed Blood Group and Rhesus (Rh) Antibodies - Infographic on your site
A blood test is carried out to determine your blood group, which could be A, B or O and your Rhesus (Rh) blood group ( positive or negative). This is partly for the records, in case a transfusion should ever be needed. If the lab finds you Rh Negative you will be tested for Rh compatibility with your baby.
