Where appropriate, medical consultation and/or genetic counseling should be offered to patients to inform and explain the risk implications and genetic implications of these test results.
Patient DNA is assayed for the Factor V Leiden G1691A mutation by polymerase chain reaction (PCR) and MOLDI-TOF mass spectrometry technology. The product of PCR is detected on the Agena Bioscience MassARRAY system.
Other causes of activated protein C resistance and hereditary forms of venous thrombosis are not ruled out. The test result must be interpreted along with the patient's clinical history and other pertinent laboratory data.
Variant analyzed: c.1601G>A (p.Arg534Gln), referred to as Factor V Leiden.
Laboratory Developed Test (LDT). This test was developed and its performance characteristics determined by Interpath Laboratory in a manner consistent with CLIA requirements. This test has not been cleared or approved by the U.S. Food and Drug Administration.
