MRX FDP is a latex immunoassay for quantifying fibrin and fibrinogen degradation products in human plasma using readers with wavelengths 500-650nm.

MRX FDP reagent consists of sub-micron sized polystyrene particles coupled to monoclonal antibodies specific for FDP. When the reagent is exposed to an FDP containing plasma sample, the particles will agglutinate, giving rise to increased light-scattering. When exposed to the appropriate wavelength of light, the increase in measured turbidity, or light-scattering, is proportional to the amount of FDP in the sample. MRX FDP is suitable for automatic coagulation and clinical-laboratory instruments using turbidimetric detection in the 500 - 650 nm wavelength range.

Specific for fibrin- and fibrinogen degradation products

Good correlation to existing FDP assays

Optimised for instruments in the 500-650 wavelength range


General Description

The determination of fibrinogen degradation products (FDP) has become a prevalent aid in the diagnosis of disseminated intravascular coagulation (DIC), pulmonary embolism (PE), deep vein thrombosis (DVT) and acute aortic dissection (AAD). The FDP assay is commonly used in some markets where the laboratories run the FDP assay in parallel with the D-Dimer assay.

Performance Characteristics

The product is used for quantitative determination of FDP in human plasma. FDP is a generic name for all fragments formed during plasmin cleavage of fibrin and fibrinogen. Whereas plasmin degradation of fibrin occurs in presence of a fibrin clot, plasmin degradation of fibrinogen occurs during over activation of the 

coagulation system causing systemic fibrinolysis. During systemic fibrinolysis, seen in patients with disseminated intravascular coagulation (DIC), activated plasmin cleaves circulating fibrinogen, rendering elevated levels of fibrinogen degradation products in the blood stream.
