Overview
Hemophilia A and B an C may be classified according to the amount of Factor VIII/ IX/ XI present respectively, resulting in either a mild, moderate, or severe form of the disease.[1]
Classification
Hemophilia A and B an C may be classified according to the amount of Factor VIII/ IX/ XI present respectively, resulting in either a mild, moderate, or severe form of the disease.
- Mild hemophilia – 5-40% of normal factor VIII/ IX activity in the blood
- Moderate hemophilia – 1-5% of normal factor VIII/ IX activity in the blood
- Severe hemophilia – less than 1% of normal factor VIII/ IX activity in the blood
Hemophilia C severity classification is different from A and B and severe Hemophilia C is defined when plasma factor XI concentration is less than 20 IU/dL[2].
