If this is done by mistake, 80% chance are developing anti-D antibodies in the transfused person. These antigens will produce antibodies in a person whose RBCs are taking these antigens. It is logical to perform only forward grouping in newborn babies. Karl Landsteiner opened the door of blood banking. If all test is negative, then the fetus is not at risk.
