Performed

Monday, Thursday
Results available in 8-11 days.

Reference Range

By report.

Test Methodology

Polymerase Chain Reaction (PCR)/ Fluorescence.

Interpretation

The PAI-1 promoter 4G/5G polymorphism located in the promoter region of the SERPINE1 gene.

Clinical Utility

The 4G allele within in the promoter region of the PAI-1 (SERPINE1) gene is associated with higher plasma PAI-1 activity when compared with the 5G allele. Heterozygosity or homozygosity for the 4G allele confers a risk for venous thromboembolism (VTE), especially in individuals with other thrombophilic risk factors, as well as a risk for myocardial infarction.
