Term Description

MCF (Maximum clot firmness): MCF is the greatest vertical amplitude of the trace. It reflects the absolute strength of the fibrin and platelet clot. A low MCF is indicative of decreased platelet number or function, decreased fibrinogen level or fibrin polymerization disorders, or low activity of factor XIII. A mechanically weak clot represents a severe bleeding risk and should initiate immediate therapeutic steps. High doses of heparin can lower MCF in the INTEM assay, but not in HEPTEM, EXTEM, FIBTEM or APTEM.

Part Description

LP270303-3   Thromboelastography.rotational
Rotational thromboelastography, also called thromboelastometry or ROTEM, is similar to traditional thromboelastography (TEG) in that it is used to measure the viscoelastic properties of a clot. In TEG, whole blood is added to a cup in which a pin is suspended, the cup is rotated, and as the clot forms, the rotational force is transferred to the pin. The movement of the pin is transformed into a tracing, from which the clotting parameters are derived. In ROTEM, the cup is stationary and the pin rotates, and as the clot forms, the rotation of the pin slows down. The torsion of the pin is transformed into a tracing from which the ROTEM parameters are derived. PMID: 22726088 Source: Regenstrief LOINC
