Note1:
The linear range for the cobas (R) HCV for EDTA plasma and serum is from 15 IU/mL to 1.00E+08 IU/mL and the accuracy of the test is within +/-0.24 log10. The lower limit of quantification (LLoQ) is 15 IU/mL
The limit of detection (LoD) of cobas (R) HCV was determined for WHO International Standard (genotype 1a) and for genotype 1b through 6. The overall LoD was 12.0 IU/mL for EDTA plasma and 13.7 IU/mL for serum
Reliable results depend on proper sample collection, storage and handling procedures. Quantitation of HCV RNA is dependent on the number of virus particles present in the samples and may be affected by sample collection methods, patient factors (i.e. age, presence of symptoms), and/or stage of infection
