The discrepancy in blood group from a previous pregnancy could be due to a laboratory error. RhD typing errors are not uncommon, and verifying the blood group with repeat testing is a standard procedure. Weak/partial RhD, Rh null phenotype, or presence of anti-D in the serum are less likely explanations in this context.
