Haemophilia: are there different types?

Yes. Each 'type' refers to the lack of a specific clotting factor.

Factors VIII and IX are the most common deficiencies, however others do exist.

Factor VIII deficiency is known as Haemophilia A while Haemophilia B refers to deficiency of Factor IX.

Haemophilia can be mild, moderate or severe, depending on the degree of the deficiency (i.e. how much factor is missing).

  • Mild haemophilia: 5-25 per cent factor VIII or IX activity.
  • Moderate haemophilia: 1-5 per cent factor VIII or IX activity.
  • Severe haemophilia: less than 1 per cent factor VIII or IX activity.
