HCVFS / 550123L

Test Code HCVFS / 550123L 
Methodology See component analytes for methodologies. 
Description Useful for: Assessment of liver status following a diagnosis of HCV. Baseline determination of liver status before initiating HCV therapy. Posttreatment assessment of liver status six months after completion of therapy. Noninvasive assessment of liver status in patients who are at increased risk of complications from a liver biopsy. 
Specimen Draw blood in either a red-top tube or serum gel tube following at least an 8hr fast. Spin down and send 3 mL (2.5 mL in first tube and 0.5 mL in second tube) of serum.Patient age and sex must be included on the test request form. Send specimens refrigerated.

NOTE: If specimen pick-up will be greater than 72hrs freeze both serum specimens.
