Implication

Assay validation study reveals rapid quantitative hirudin measurement in blood and plasma, indicating reliable therapeutic dose monitoring independent of heparin.

Key Points

Develop a rapid, sensitive, and reproducible coagulation-based assay to accurately measure hirudin levels in blood and other body fluids for precise clinical dose monitoring.
Designed the ecarin clotting time (ECT) assay utilizing ecarin, a purified Echis carinatus venom enzyme, to activate prothrombin into meizothrombin without cofactors.
Evaluated assay responsiveness across hirudin concentrations and tested for interference from variable fibrinogen levels (60% to 100%), prothrombin levels (20% to 100%), and heparin.
Demonstrated an excellent linear correlation between ECT prolongation and hirudin concentrations ranging from 50 to 5,000 ng/mL in blood and plasma.
Observed that test results remain virtually independent of physiological fluctuations in prothrombin and fibrinogen levels, while also avoiding interference from heparin.
