Order Display Name: Geisinger Epic Procedure Code Or ID CPT Code:  

FIBRINOGEN

ORDERING INFORMATION:
Geisinger Epic Procedure Code: LAB2283         Geisinger Epic ID: 7170

SPECIMEN COLLECTION
Specimen type:
Platelet-free plasma
Preferred collection container:
Alternate Collection Container:
Other size blue-top (3.2% sodium citrate) tubes (e.g., 1.8 mL, 4.5 mL)
Specimen required:
1 mL aliquot of plasma.
Special notes:
Do not draw blood from a heparinized line. Avoid contaminating the sample with tissue thromboplastin or heparin. Venipuncture must be performed with no trauma. If blood is drawn from an indwelling catheter, flush with 5 mL of saline and discard the first 5 mL of blood collected. If drawn with a butterfly setup, draw a discard first to remove air from tubing.

SPECIMEN PROCESSING
Specimen processing instructions:
Centrifuge the citrated blue-top tubes as soon as possible (within 60 minutes) at designated time and speed to obtain platelet-poor plasma (<10,000/µL). Using a plastic pipette, remove 1 mL of plasma and transfer to a plastic polypropylene aliquot tube and label with patient's name and a second patient identifier (e.g., date of birth, medical record number). Freeze upright and transport on dry ice. 
Transport temperature:
Frozen.
Specimen stability:
Frozen: -20°C for 30 days, -70°C for 6 months. Room temperature: 8 hours.
Rejection criteria:
Clotted specimen. Stability limits exceeded. Overfilled or underfilled tube. HCT > 55. HCT > 55 requires rejection, reorder in LIS, and recollection with proper adjustment of anticoagulant. Indications of thaw in transit are sample on slant in aliquot tube or in lid of tube. These samples will be run but will receive a comment of interpret results with caution as thawing suspected.

Test includes:
Fibrinogen.
Methodology:
Clauss
Thrombin Clotting Rate Assay
Synonyms:
FIB
Clinical significance:
Low levels of fibrinogen can lead to poor clot formation and bleeding disorders. Elevated levels are seen in reactive processes. A high level can be associated with thrombosis.
