Also Known as
F8, Factor 8, FVIII, Hemophilia, Hemophilia A
This testing is recommended for the detection of germline variants associated with severe Hemophilia A . Testing begins with F8 inversion Analysis; if this analysis is negative, F8 Sequence Analysis is performed at an additional charge. Refer to F8 Inversion Analysis and F8 Sequence Analysis for test information.
