Like most aspects of the disorder, life expectancy varies with severity and adequate treatment. People with severe haemophilia who do not receive adequate, modern treatment have greatly shortened lifespans and often do not reach maturity. Prior to the 1960s when effective treatment became available, average life expectancy was only 11 years. [21]
[4] [10] The prolongation of the activated partial thromboplastin time should completely correct with a 1:1 mixing study with normal plasma if haemophilia C is present; in contrast, if a lupus anticoagulant is present as the cause of a prolonged aPTT, the aPTT will not correct with a 1:1 mixing study.

X chromosome. The factor IX gene is located on the X chromosome (Xq27.1-q27.2). It is an X-linked recessive trait, which explains why males are affected in greater numbers. [9] [10] A change in the F9 gene, which makes blood clotting factor IX (9), causes haemophilia B. [11]

Physicians specialized in hematology are known as hematologists or haematologists. [2] Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope, interpreting various hematological test results and blood clotting test results.

Contaminated hemophilia blood products were a serious public health problem in the late 1970s up to 1985. Hemophilia A causes a deficiency in Factor VIII , a protein required for blood clotting. Factor VIII injections are a common treatment to prevent or stop bleeding in people with hemophilia A. [ 1 ]
