If you suspect that you may develop hemophilia, you can undergo a test of a blood sample to see the level of factor activity in your blood. The diagnosis of hemophilia A and hemophilia B is based on two different clotting factors, factor VIII and factor IX respectively.
Some mothers are carriers of hemophilia. Tests before a baby is born are necessary. You can undergo prenatal diagnosis by either chorionic villus sampling or fetal blood sampling. The first one is done at 9 to 11 weeks, while the later one is done much later, about 18 or more weeks.
