Factor V Leiden Gene Mutation Analysis [FVPCR]

Factor V Leiden Gene Mutation Analysis [FVPCR]
WSLH Department: Cytogenetics
WSLH Test Code:842C90
CPT Code: 
Price: 
Includes:Test Component:
Factor V Leiden gene mutation analysis by real-time PCR amplification and melting point analysis. Factor V Leiden Gene Mutation Analysis is useful for confirming the diagnosis of resistance to APC as identified by functional coagulation testing. It can also be used to establish the diagnosis of resistance to APC in patients in whom functional coagulation testing may not be feasible, for example, patients on anticoagulant therapy (especially heparin) or positive for Lupus anticoagulants. Usually ordered with the Factor V is a test for the Prothrombin G20210A allele, which has been associated with elevated plasma prothrombin levels and moderately increased risk of first venous thrombotic events.
