The manufacturer’s Instructions For Use document should be reviewed carefully when making exceptions for the use of plasma samples. Citrated plasma has been shown to lower the signal/cutoff (s/c) values in some anti-HCV reactive samples. High negative results (0.80-0.99 s/c) obtained on samples collected with this anticoagulant should be interpreted accordingly. Additional testing may be required.
