Plasminogen activator inhibitor 1 (PAI-1) 4G/5G polymorphism-994

Test name:

Test number:

994

Excellian order number:

LAB994

Abbreviation:

MSO

Alternate names:

Plasminogen activator inhibitor (PAI-1)
Gene polymorphism
PAI-1 4G/5G Polymorphism

Useful for:

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.
