What is the hemophilia test used to detect?

The hemophilia test is used to detect deficiencies in specific clotting factors in the blood, primarily factor VIII (Hemophilia A) and factor IX (Hemophilia B). It typically involves measuring activated partial thromboplastin time (aPTT) and performing specific factor assays to identify any deficiencies. The test helps diagnose hemophilia, assess its severity, and guide treatment options for affected individuals.
