Fibrinogen Activity
MessagePerformed in Coagulation
Test Code
FIB
Preferred Specimen
3.2% sodium citrate - blue top tube
Minimum Volume
1.8 mL
Instructions
The light blue capped tubes, containing 3.2% buffered sodium citrate, used for coagulation testing must be allowed to fill completely (after filling a small air space will normally be present). We cannot accept a short filled tube.
Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Clotted Serum received instead of Sodium Citrate plasma
Specimen past stability
Frozen plasma received thawed
Underfilled or Overfilled, blood/anticoagulant ratio must be 9/1; Specimens must be between 90% -110% full
Collected in a 3.8% Sodium Citrate tube instead of 3.2% Sodium Citrate tube
Drawn in outdated/expired tube
Hemolyzed, icteric, or lipemic sample

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.
