Test Code 030 Fibrin Split Products (FSP)

Additional Codes

MLAB: FDP

PowerChart: FbDP/FSP Agglutination Semiquantitative

Epic: LAB761 Fibrin Split Products

MA Cerner: Fibrin Split Products.

Test Method

Latex Agglutination, Thrombo-Welco Test; Remel

Specimen Requirement

2 mL whole blood is required.

Additional Specimen Collection Information

Collect blood in a special vacuum tube provided in the Thrombo-Welco Test kit. The tube will draw only 2 mL total volume. Place the 2 ml Thrombo-Welco tube in a 37°C waterbath/incubator for 30 to 60 minutes to ensure complete clotting. Centrifuge the tube and transfer the serum to a glass tube until ready to test. After clear serum has been collected, the sample may be stored refrigerated for up to one week or frozen for a longer periods of time.

Performance

Testing is performed Monday through Sunday.

Routine: Typically completed within 4 hours after the speicmen arrives at the testing site

STAT: Typically completed within 1.5 hours after the specimen arrives at the testing site

Reference Values

Negative

Mean normal serum FDP is 4.9 ± 2.8 mcg/mL. FDP levels are calculated by a factor of 2 mcg/mL, therefore, a 1:5 dilution corresponds with 10 mcg/mL and a 1:20 dilution corresponds with 40 mcg/mL. Normal or slightly elevated samples will yield negative results in both dilutions.

CPT Code Information

85362 Coagulopathy Testing: Fibrin degradation (split) products (FDP)(FSP), agglutination slide, semiquantitative

Useful For

Determine the amount of fragment proteins present in the blood released when a clot and fibrin net dissolve, presence of excessive amounts of FDP in the circulation can indicate a clotting disorder
