General Information

Clinical assay interference and limitations: When the fibrinogen assay is to be performed on samples collected from patients receiving thrombolytic therapy and without addition of an anticoagulant mixture containing a plasmin inhibitor in the collection tube, fibrinogen results may be underestimated. Fibrinogen assay is insensitive to fibrin degradation products (up to 130 ug/mL), hirudin (up to 3 ug/mL) and heparins (UFH and LMWH) (up to 2 IU/mL).
