The linear...

The linear range for the cobas (R) HBV for a 500 uL sample processing volume for EDTA plasma and serum is from 10 IU/mL to 1.00E+09 IU/mL with an accuracy within +/-0.24 log10
The lower limit of quantification (LLoQ) is 10 IU/mL

The limit of detection (LoD) of cobas (R) HBV for 500 uL sample processing volume is 6.6 IU/mL for EDTA plasma and 3.5 IU/mL for serum. The same LoD has been verified for genotypes A through H and the predominant precore mutant

Reliable results depend on proper sample collection, storage and handling procedures. Quantitation of HBV DNA 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
