Fibrin monomer

Last updated

Fibrin monomers are monomers of fibrin which are formed by the cleavage of fibrinogen by thrombin. [1] Levels of fibrin monomers can be measured using blood tests and can serve as a marker of in vivo fibrinogenesis and coagulation activation. [1] [2] [3] They may be useful in the evaluation of hypercoagulability, [1] as reflected in research studies done using fibrin monomers.

Levels of fibrin monomers may be increased with pregnancy [1] and by estrogen-containing combined birth control pills. [2]

Significance in venous thromboembolism

Increased amount of soluble fibrin monomers in the blood along with serum D-dimers have been found to be indicators of venous thromboembolism (VTE). [4] [5] Detection of VTE in such a way have implications for treating VTE taking place during pregnancy and after hepatobiliary-pancreatic surgery. [4] [5]
