Objective To evaluate the performance of NP968 nucleic acid extraction (MACS)-based real-time fluorescence quantitative PCR detection system for hepatitis B virus DNA (HBV DNA). Methods Using the NP968 automated nucleic acid ex-traction system (MACS) to extract HBV DNA from the serum , and the DNA was detected by real-time fluorescence quantitative PCR system. In order to evaluate the performance of the detection system for HBV DNA, the precision, linearity, recovery rate, the lowest detection limit and reference interval of the testing system have been analyzed, and the correlation analysis with traditional boiling method was carried out. Results In the NP968 nucleic acid extraction (MACS)-based real-time fluorescence quantitative PCR detection system for HBV DNA, the within-run precision of the low and high level are all<3/5TEa (target TEa=0.4/value x 100%) and the between-run precision are all <4/5TEa; In the range of 4.16E2-4.16E8 IU/ml ,there has good linear relationship (Y=1.010X+0.271, R2=0.989); the recovery rate is 104%. The minimum detection limit is 1.00E2 IU/ml; reference interval is <1.00E3 IU/ml, and the detection results between boiling method and MACS-based real-time fluorescence quantitative PCR has a good correlation (X+Y=0.995 0.995, R2=0.951). Conclusion The NP968 nucleic acid extraction (MACS)-based real-time fluores-cence quantitative PCR detection system can extract the HBV DNA quickly and automatically and has good detection performance, so the detection system is suitable for clinical application.
