Fibrinogen Level

Medical Necessity Documentation:  
Client Notes:  
Patient Preparation:  
Specimen Requirements: 2.7 mL Whole Blood in a Blue Top Tube - 3.2% Buffered Sodium Citrate
Collection Instructions: Specimens must be filled appropriately see this example

Correct ratio of Blood to Citrate is critical (9:1). Specimens must be filled within +/- 10% of stated volume.

If a Blue Top Tube is collected utilizing a butterfly, a Blue Discard Tube must be drawn first to remove air from the line. If this is not done, the Blue Top Tube will not be filled properly due to the vacuum in tube and a redraw will be required

Heparinized Patient specimens must be spun within 1 hour of collection

Note: Collection of blood for coagulation testing through intravenous lines that have been previously flushed with heparin should be avoided, if possible. 
If the blood must be drawn through an indwelling catheter, possible heparin contamination and specimen dilution should be considered. 
When obtaining specimsn from indwelling lines that may contain heparin, the line should be flushed with 5mL of saline, and the first 5 mL of blood or 6-times the line volume
(dead space volume of the catheter) be drawn off and discarded before the coagulation tube is filled. For those samples collected from a normal saline lock (capped off venous port) twice the dead space volume of the catheter and extension set should be discarded.

Minimum Volume: 1.8 mL Whole Blood in a Clear Blue Top Tube
Transport & Storage: Temperature/Stability: 24 hours Ambient
24 hours Refrigerated
Rejection Criteria: clotted; underfilled; overfilled; inappropriate temperature; HCT >55%; cell volume > 1/2 the tube volume; Frozen; Thawed specimens
Reference Range: Normal: 150 - 440 mg/dl
Critical Ranges:
Low: <= 80 mg/dL
Test Comments:  
Methodology: Clauss Fibrinogen
Clinical Significance: Decreased fibrinogen levels are associated with increased bleeding tendencies. Increased fibrinogen levels are a risk factor for thrombotic complications.
