Soluble Fibrin Monomer
Also known as: SFM
Use
The Soluble Fibrin Monomer test is used to assess potential ongoing intravascular coagulation and thrombosis. It is typically not recommended for routine evaluation and D-dimer testing is preferred as the initial evaluative step for thrombosis-related anomalies. Soluble fibrin monomer complexes are formed at the initiation of fibrin clot formation and can increase in conditions associated with states of increased coagulation and thrombosis.
Special Instructions
It is important to follow proper specimen collection procedures to avoid false-positive results due to improper technique. This test is New York state approved, indicating it has met specific regulatory standards required for testing within the state.
Limitations
The test may yield false-positive results if the specimen gets activated due to improper venipuncture technique. Furthermore, organ damage or excessive inflammation may lead to a misinterpretation of results. It is not the primary test recommended for thrombotic conditions, as alternatives like D-dimer provide broader indications.
