What is Plasminogen Activator Inhibitor-1?

The Plasminogen Activator Inhibitor-1 (PAI-1) test is performed to keep a check on the PAI-1 protein as high PAI-1 depresses fibrionolytic activity which leads to an increased probability of venous and arterial thrombosis. On the other hand, deficiency of PAI-1 can lead to excessive bleeding due to any injury.

Why is Plasminogen Activator Inhibitor-1 done?

PAI-1 deficiency causes excessive bleeding due to any injury or physical trauma. If left undetected, the PAI-1 level may reduce even further and that can even prove to be fatal in the worst case.

The normal PAI-1 range is 2-15 AU/mL.
