Abstract
Objective To evaluate the performance and clinical application of an easy operated method for HBV‐DNA .Methods 137 HBV clinical serum samples were tested quantitatively with boiling method and the new one‐step method ,and their sensitivity ,consistency and correlation of quantitative results were compared;Investigate the accuracy by detecting the EQA specimens from Ministry of Health Clinical Laboratory Center in the first half of 2014 ;Using one‐step method to test the gradient‐diluted samples ,detect its linear range and sensitivity ;Using one‐step method to .detect two cases for five times and investigate its accuracy .Results The consistency of positive de‐tection rate of the one‐step method and boiling method was 100% (93/93) ,the negative detection rate was 90 .91%(40/44)and the total conformance was 97 .08% .The four inconsistent samples′virus was positie for low concentra‐tion with the one‐step method again ,which negative for the boiling method .After reviewing the two quantitative re‐sults ,the t=0 .53(P>0 .05) ,r=0 .967 ,which shows that the detection result of one‐step method and boiling method was consistency .The quantitative results of the EQA specimens were within the scope of qualified by the one‐step method ,showing it has a scientific traceability system .;Using one‐step method to detect two cases(high concentra‐tion and low concentration)five times ,the coefficient of variation was CV=0 .049% and CV=0 .108% which shows that the precision of the one‐step method was good .Conclusion The one‐step method shows much better accuracy and sensitivity than the boiling method .With a simple procedure ,this method is suitable for clinical diagnosis .关键词
