Time Sensitive
  


Mnemonic: VTE

Methodology: Enzyme Immunoassay
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Collect: Lt. blue (sodium citrate).Refer to Specimen Handling at aruplab.com for hemostasis/thrombosis specimen handling guidelines.

Specimen Preparation: Separate plasma from cells within 2 hours of collection. Transfer 1 mL platelet poor plasma to an ARUP Standard Transport Tube (Min 0.5 mL)

Storage/Transport Temperature: Room temperature.

Unacceptable Conditions: Serum.

Stability (collection to initiation of testing): After separation from cells: Ambient: 8 hours; Refrigerated: 8 hours; Frozen: 1 month
Reference Interval:
Negative
Interpretive Data: This test is intended for use as one component of a clinical algorithm for determining the likelihood of venous thromboembolism (VTE) in an outpatient setting. Patients with negative values are unlikely to have VTE; however, false negatives may occur more commonly in patients with cancer. Positive results are not useful due to the poor positive predictive value of the test. This test is not currently available for inpatient testing due to low specificity. This test is not useful for diagnosing or following patients with DIC. The cutoff value is greater than or equal to 0.5 µg/mL (Fibrinogen Equivalent Units).
CPT Code(s): 85380
