Fibrinogen, Plasma
Test CodeFIB - NOCO
CPT Codes
85384
Preferred Specimen
1.0 mL plasma from Blue Top (Na Citrate)
Minimum Volume
Full blue top tube or 1.0 mL plasma frozen
Instructions
- It is imperative that the tube be completely filled to frosted line. The ratio of blood to anticoagulant is critical for valid coagulation results. If obtaining blood with a syringe, fill the light blue-top (sodium citrate) tube first.
- If patient is on heparin, specimen must be centrifuged and separated within 1 hour of draw.
- Heparin contaminated tube is not acceptable.
- Keep specimen anaerobic.
- Patients with an extremely high hematocrit may require special tubes before obtaining blood for coagulation testing. Please contact the lab for further information.
- If testing will not be completed within 4 hours, spin down, remove plasma, and spin plasma again, and send specimen frozen in plastic vial.

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Gross hemolysis, clotted, insufficient volume
Setup Schedule

Same day
Reference Range
188-433 mg/dL
Critical value (automatic call-back): <100 mg/dL
Critical value (automatic call-back): <100 mg/dL
Clinical Significance
When unexplained bleeding or abnormal clotting occurs, it may be of clinical importance to quantitate fibrinogen. Fibrinogen is also a useful marker in the evaluation of several disease states including Disseminated Intravascular Coagulation, liver disease and inflammatory diseases.
