Correct Answer � A:E Explanation

Ans. A & E

Hemophilia A is four times as common as hemophilia B

Ie. Hemophilia A constitutes 80-85% of total hemophilia cases.

More than half of patients with hemophilia A have the severe form of hemophilia.

Prothrombintime and platelet count will remain normal in hemophilia A & hemophilia B.

Cryoprecipitate is derived from blood and contains a moderately high concentration of clotting factor VIII (but not IX).

So it can be used in hemophilia A but not in hemophilia B.
