Test Overview
Test Methodology

PCR-RFLP

Test Usage

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 higher in individuals with the 4G/4G genotype.

Reference Range *

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

Genetic testing by PCR provides exceptionally high sensitivity and specificity. Incorrect genotyping results can be caused by rare polymorphisms in primer binding sites. This assay analyzes only the PAI 4G/5G locus and does not measure genetic abnormalities elsewhere in the genome.
