Diagnosis of Haemophilia
This is made from the family history, the history of bleeding, and, from blood tests that demonstrate the lack of the normal clotting processes. The clotting time is the time taken for blood run into dry tubes to clot.
It is normally four to seven minutes. Blood from a haemophiliac person takes longer to clot.Laboratory tests can also demonstrate the levels of the various clotting factors present in the blood. In haemophilia there is a shortage of either factor VIII or factor IX.
