What is a Fibrinogen Activity Test?
Bleeding disorder evaluation
Low fibrinogen activity impairs clot formation and increases bleeding risk — from inherited fibrinogen disorders to acquired causes like liver disease, DIC, or consumptive coagulopathy. Identifying functional deficiency guides appropriate treatment with fibrinogen concentrate or plasma products.
DIC and coagulation crisis monitoring
Disseminated intravascular coagulation (DIC) causes rapid consumption of fibrinogen and other clotting factors. Serial fibrinogen activity testing tracks the severity and progression of DIC, informing urgent treatment decisions in critically ill patients.
Inflammation and cardiovascular risk marker
Fibrinogen also functions as an acute phase reactant — levels rise with infection, inflammation, and chronic disease. Chronically elevated fibrinogen is associated with increased cardiovascular risk and provides additional context when assessing overall cardiometabolic health.
