"but >69,000,000 IU/mL" indicate that the level of HCV RNA present is above the quantifiable upper
limit of this assay. A single negative HCV RNA result with positive anti-HCV antibody status (assay
signal-to-cutoff ratio of > or =3.8 by EIA, or > or =8.0 by chemiluminescence immunoassay), does not
necessarily indicate past or resolved HCV infection. Individuals with such results should be retested for
HCV RNA in 1 to 2 months, to distinguish between patients with past or resolved HCV infection and
those with chronic HCV infection having episodic HCV replication. Presence of anti-HCV antibodies
(assay signal-to-cutoff ratio of or =95% probability) of the true anti-HCV status, but additional testing is needed to
differentiate between past (resolved) and chronic hepatitis C. To confirm results of HCV antibody
screening test and to guide further management of patients, specimens should be tested by 1 of the
following supplemental tests: -HCVQU Hepatitis C Virus (HCV) RNA Detection and Quantification by
Real-Time Reverse Transcription-PCR (RT-PCR), Serum for patients with known risk factors for HCV
infection. Presence of HCV RNA in a given specimen indicates acute or chronic hepatitis C.
