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. Centrifuge within 24 hours of collection. If testing isn’t completed within 24 hours, transfer plasma to plastic tube using a plastic transfer pipette. Freeze specimen < 20°C(Exception-WYMC requires centrifugation and freezing withing 8 hurs of collection)
Transport Container
Room temperature preferred (15-25°C)
Specimen Stability
| · Unopened Collection Tube < 24hours (8 hours for WYMC) |
| · Opened Collection Tube < 4 hour, |
| · Frozen plasma 2 weeks at -20° to -50°C |
Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
| · clotted specimens |
| · underfilled or overfilled tube |
| · collection in 3.8% Citrate |
| · specimens collected in expired tubes |
| · serum samples |
| · specimen past stability |
| · thawed frozen samples |
| · 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.
