Preferred Specimen

Lt Blue Citrate; Dark Blue FDP

Completely fill the Blue Top (sodium citrate) tube. Underfilled tubes will not be accepted. Mix sample immediately by gentle inversion at least six times

Minimum Volume

2 mL

Instructions

Routine venipuncture Collect one Light Blue top -- Citrate tube

Methodology
direct latex agglutination (semi-quantitative)

Setup Schedule

Daily

Report Available

Within 24 hours STAT: 1 hour after collection

Limitations

Fibrin degradation products are found at low levels in the sera of all healthy individuals because of normal fibrinolytic mechanisms. The mean normal levels in resting adults is 4.9 +/- 2.8 ug/mL.

Reference Range

Less than 10 ug/mL

Clinical Significance

Fibrin degradation products are found at low levels in the sera of all healthy individuals due to normal fibrinolytic mechanisms. Elevated FDP
levels are associated with disseminated intravascular coagulation (DIC), deep vein thrombosis, some pregnancy disorders, myocardial infarction
and pulmonary embolisms.
