Core Tip

Core tip: The TianLong automatic hypersensitive hepatitis B virus DNA quantification system achieved a limit of detection of 10 IU/mL, limit of quantification of 30 IU/mL and good analytical performance in terms of accuracy, precision, reproducibility, linearity, genotype coverage and cross-contamination. In clinical performance, the TL system showed good correlation and agreement with the Roche CAP/CTM system.
