Discusses hemophilia, a congenital condition of impaired blood-clotting capability. Why hemophiliacs often require transfusions; Estimated number of United States hemophiliacs who contracted HIV before adequate testing was implemented in the 1980s; Factor VIII and Factor IX; US Institute of Medicine (...
Hemophilia diagnosis and testing Last updated Oct. 20, 2023, by Marisa Wexler, MS Fact-checked by Joana Carvalho, PhD Family history Blood tests Screening tests Clotting factor tests Signs to get tested Hemophilia is a disorder wherein the blood is not able to clot properly. As a result, pa...
Other screening tests, which can be used to assess overall blood health and clotting ability, may be useful for ruling out other conditions that can cause excessive bleeding. These include a complete blood count, known as a CBC, the activated partial thromboplastin time or APTT test, the ...

Genetic testing can identify carriers of hemophilia, and the status of fetuses can be now be ascertained early in pregnancy. Treatments under study include gene therapy by insertion of healthy factor VIII or IX genes and fetal tissue implants....
Genetic testingGenetic TestingDetection of a mutation; genotype; karyotype; or specific alleles associated with genetic traits, heritable diseases, or predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.Myotonic Dystrophies: ...
The diagnosis of hemophilia combines an index of suspicion due to familial history and clinical manifestation, as well as laboratory testing. Screening tests are necessary for families with an active carrier status or for those who have a family history of excessive bleeding after trauma or after ...
Clotting factors made from human blood can carry the viruses that cause HIV/AIDS and hepatitis. However, the risk of getting an infectious disease from human clotting factors is very small due to: Careful screening of blood donors Testing of donated blood products Treating donated blood products ...
Women whose carrier status is unknown can be evaluated either by testing for the clotting factors or by methods to characterize the mutation in the DNA. DNA screening methods are generally the most reliable. Prenatal diagnosis is also possible with DNA-based tests performed on a sample obtained ...
THE RELATIVE EFFICACY OF GENETIC ANALYSIS AND COAGULATION TESTING IN THE DIAGNOSIS OF CARRIERS OF HEMOPHILIA A This study has assessed the relative benefits of restriction fragment length polymorphism (RFLP) linkage and coagulation testing in the diagnosis of carriers of hemophilia A. 221 samples from...
