Clinical Information

Useful for the detection and semi-quantitation of fibrin/fibrinogen degradation products in plasma with latex particles which are coated with monoclonal antibodies to FDP. 

 

Abnormal fibrinolytic and or fibrinogenolytic activity demonstrated by elevated levels of FDP in plasma may be seen in the following:

  • DIC
  • Eclampsia
  • Carcinoma
  • Post-operative
  • Cardiac or hepatic disorders
  • Fibrinolysis
  • Pulmonary embolism
  • Deep vein thrombosis

 

Interpretation:

Free D and E domains as well as X and Y fragments detected by this method may be produced by degradation of either fibrin clot or circulating fibrinogen.

In cases where the FDP assay is positive and it is desired to distinguish lysis of fibrin from intravascular fibrinolysis, it is recommended to suggest the D-Dimer assay.

 

Limitations:

The slightest coagulation of the specimen may produce false positive reactive with the FDP plasma.  High levels of rheumatoid factor (RF) may lead to false agglutinations.  Any suspected presence of RF should be confirmed by a separate test for RF. 

The FDP Plasma test is insensitive to heparins up to 2 IU/ml.

The presence of anti-mouse of antibodies in certain subjects may lead to aberrant test results.
