Fibrin Monomer

Fibrin Monomer (HCFIBMON) Coagulation Lab Test

Name: Fibrin Monomer

Test Name: Fibrin Monomer

Health Link Test Code: HCFIBMON

LIS Test Code: FIBMON

CPT Code(s): 85362

Methodology: Hemagglutination

Clinical Information:

Fibrin monomers, intermediate products between fibrinogen and fibrin, are produced during the proteolysis of fibrinogen by thrombin. This test is useful in the assessment of DIC in a patient.

Days Performed: Daily, 24 hours.

In-Lab Turnaround Time: 1 day.

Stat In-Lab Turnaround Time: 1 hour.

Specimen: Blood

Collection Container: Light blue top (3.2% NaCitrate)

Collection Instructions:

Fibrin monomer results are greatly affected by specimen collection procedure and technique. The venipuncture MUST be atraumatic to avoid hemolysis and contamination with tissue factors and platelets. Tube must be allowed to fill up to "fill" line located on tube.

Collection Volume: 3.5 mL

Pediatric Collection Volume: 1.8 mL

Stability Ambient:

4 hours unspun; 2 hours if spun and opened

Sample Analyzed: Plasma

Testing Volume: 1 mL

Pediatric Testing Volume: 0.5 mL

Specimen Processing:

Centrifuge specimen to yield platelet poor plasma (platelet count should be less than 10 K/uL). Separate plasma and transfer to plastic tube or vial.

Specimen Transport:

Transport whole blood specimen at room temperature to UWHC Hospital Laboratory within 4 hours of collection. See "Specimen Processing" for instructions if transport criteria can not be met.

 

Transport frozen plasma aliquot on dry ice to UWHC Hospital Laboratory.

Unacceptable Criteria:

Hemolyzed specimens, clotted specimens, partially filled tubes and whole blood specimens greater than 4 hours old when received by the laboratory are not acceptable.

Interpretation:

18 years and up: Negative

Interpretation Type: Expected Results
