- 1/14 samples with discrepant routine D phenotype results Afro-Caribbean (in the French population)
- 4/627 weak D typing (95% from patients, 5% from donors; 21,2% were identified as RHef00442 or RHef00446 by authors, "mostly (…) inconclusive serology consequent to recent transfusion") in the Belgian (Flanders) population
