Liver Fibrosis - FibroMeter Vibration Controlled Transient Elastography (FibroMeter plus FibroScan VCTE)
Noninvasive assessment of liver fibrosis in patients with chronic viral hepatitis B or C (with or without HIV coinfection) and in patients with hepatic steatosis. Test can be performed only if the patient has a FibroScan score. Result based on both a panel of serum biomarkers (FibroMeter) and the FibroScan Vibration Controlled Transient Elastography (VCTE), a noninvasive, diagnostic ultrasound-based test that measures liver fibrosis.
Quantitative Nephelometry/Quantitative Enzymatic/Quantitative Spectrophotometry/Automated Cell Count/Electromagnetic Mechanical Clot Detection/Vibration Controlled Transient Elastography
Patient must be 18 years of age or older. Platelet count should be performed on the EDTA whole blood sample at the client site within 3 days of submission for testing.
Lavender (K2EDTA) or Pink (K2EDTA) AND Serum Separator Tube (SST) AND Light Blue (Sodium Citrate).
Separate from cells ASAP or within 2 hours of collection. Transport 3 mL serum in an ARUP Standard Transport Tube. (Min: 1.2 mL) AND Transport 1 mL platelet-poor citrated plasma in an ARUP Standard Transport Tube. (Min: 0.5 mL) Do not send the EDTA whole blood to ARUP.
Plasma (citrated): CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered.
All required specimens not received. No platelet count received. VCTE performance date greater than 6 months from the specimen draw date and time. Hemolyzed specimens.
Include an automated platelet count. The Liver Stiffness result (in kPa) from the Fibroscan VCTE must be submitted with the samples. The performance date of the VCTE must also be submitted.
Serum: Ambient: 8 hours; Refrigerated: 1 week; Frozen: 2 weeks
Plasma: Ambient: 24 hours; Refrigerated: Unacceptable; Frozen: 2 weeks
Refer to report.
Laboratory Developed Test (LDT)
Delays in test performance may result if the VCTE result and date of performance is not included with the requisition.
