Hemophilia B lack of clotting factor IX (FIX). Hemophilia A and B cannot be distinguished because it has a similar clinical appearance and a similar pattern of gene inheritance.

Hemophilia is a genetic disease of the oldest ever recorded. Inherited bleeding disorder that occurs in a male was recorded in file Talmud in the Second Century. Modern history of hemophilia began in 1803 by John Otto was there a child who suffered from hemophilia.

Proof disability in process of blood clotting in hemophilia conducted by Wright in 1893. However, factor VIII (FVIII) have not been identified until 1937 when Patek and Taylor managed to isolate from the blood clotting factor, which was called anti hemophilia factor (AHF).

In the early 1960s, cryoprecipitate was the first time there's concentrate for the treatment of hemophilia. In the 1970s, lyophilized intermediate-purity concentrates concentrate or pure medium liofil first created from a collection of donor blood.
