Fibrinogen
General Information
- Lab Name
- Fibrinogen
- Lab Code
- FIBCL
- Epic Name
- Fibrinogen
- Description
The fibrinogen activity is a coagulation screening test using the Clauss clotting method to measure the rate of fibrinogen to fibrin conversion under the influence of excess thrombin. The level of fibrinogen in the plasma is used to monitor severity and treatment of DIC, fibrinolysis, advanced liver disease and cirrhosis, acute or chronic inflammatory illnesses, pregnancy or estrogen therapy, and therapy with fibrinolytic agents (e.g streptokinase, tissue plasminogen activator).
- Synonyms
- Ancrod Fibrinogen, Kinetic Fibrinogen
- Components
Interpretation
- Method
Stago STA clotting assay (Clauss fibrinogen)
- Reference Range
-
Units: mg/dL
Female Male Age Range Age Range 0- 150-450 0- 150-450 Effective date: 01/26/2015
- Ref. Range Notes
Note: Present assay measures Kinetic Fibrinogen
- Interferences and Limitations
Clinical assay interference and limitations: When the fibrinogen assay is to be performed on samples collected from patients receiving thrombolytic therapy and without addition of an anticoagulant mixture containing a plasmin inhibitor in the collection tube, fibrinogen results may be underestimated. Fibrinogen assay is insensitive to fibrin degradation products (up to 130 ug/mL), hirudin (up to 3 ug/mL) and heparins (UFH and LMWH) (up to 2 IU/mL).
