ABSTRACT
【Objective】 To compare the quantitative detection results of two domestic quantitative real-time PCR reagents in HBV-DNA detection. 【Methods】 A total of 306 serum samples form hepatitis B patients were selected for quantitative parallel detection of high-sensitiveity HBV-DNA using domestic reagent A and B, and the difference and consistency of the results were analyzed. 【Results】 1) The yielding rate of reagent A and B was 86.92% and 84.64%, respectively. The regression linear equation was Y=0.984 9x+ 0.154 9, R2=0.945 7, the correlation coefficient r=0.972 5, indicating the results by the two reagents had good correlation. 2) When the concentration was in the range of(20~1 000) IU/mL, the yielding rates of reagent A and B were 39.9% and 37.6%, respectively. 【Conclusion】 Reagent A is more suitable for post-treatment monitoring in patients with OBI and HBeAg(-), but also can be used to detect HBV pathogens in patients before operations or blood transfusions.
