    Limitations

    This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. The FDA has determined that such clearance or approval is not necessary. Results of this test are for investigational purposes only. The result should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically established diagnostic product or procedure.

    Methodology

    Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) technologies

    Additional Information

    Deep vein thrombosis (DVT) and coronary artery disease (CAD) are associated with increased PAI-1 levels. Elevated PAI-1 levels may help predict risk of reinfarction in survivors of myocardial infarction, particularly in young individuals. PAI-1 levels tend to be lower in individuals with 4G/5G or 5G/5G genotype compared to a 4G/4G genotype.
