Diagnosing Haemophilia The Haemophilia Society The diagnosis of haemophilia may be expected or suspected where there is a family history, or it may be completely unexpected. the following investigations lead to the diagnosis: history, signs and symptoms of bleeding. family history of bleeding. family history of haemophilia. blood tests – a general test of blood clotting called a clotting. Diagnosing hemophilia.
Understanding Haemophilia The Haemophilia Society Autoimmune (acquired) hemophilia: updates in diagnosis. Haemophilia is a lifelong, inherited bleeding disorder. in haemophilia one of the clotting factor proteins important for blood clotting is either partly or completely missing. people with haemophilia take longer than normal for bleeding to stop. they may have bleeding into joints and muscles without having had an injury, so treatment is aimed. Diagnosis is made using a series of blood tests to measure the level of clotting factor activity. if there is a known family history of haemophilia, genetic testing can be done during pregnancy. genetic testing may also be performed to look at the genetic variant that is causing the haemophilia. the haemophilia society. Haemophilia, which means love (“philia”) of blood (“haemo”), is associated with prolonged and excessive bleeding. it is a hereditary disorder of haemostasis that occurs in one in 5000 men (prevalence of 10 in 100 000 people) and is caused by a deficiency of clotting factor viii (in haemophilia a) or factor ix (in haemophilia b) as a result of defects in the f8 and f9 genes.

The clinical manifestations and diagnosis of hemophilia a and b will be reviewed here, along with a discussion of obstetrical issues. other issues related to care for people with hemophilia are presented separately. routine care including prophylaxis – (see "hemophilia a and b: routine management including prophylaxis" .). • accurate diagnosis of hemophilia is essential to inform appropriate management. a definitive hemophilia diagnosis is based on a factor assay to demonstrate deficiency of fviii or fix. • see chapter 3: laboratory diagnosis and monitoring and chapter 4: genetic assessment. bleeding manifestations.
