The comparison test analysis of nucleic acid sequencing method and fluorescence PCR method for HBV genotyped.

Objective To comare the sensitivity and specificity of the nucleic acid sequencing methods and fluorescence PCR method used for hepatitis B virus （HBV） points to the detection and classification accuracy. Methods The sensitivity, specificity and classification type of calculating HBV type were calcualted by nucleic acid sequencing method and fluorescence PCR methods. Results 200 eases of samples, 78 cases are positive according to gold standard test result. In the 78 cases, result of 78 cases by fluorescence PCR deteetion method were positive. The sensitivity of fluorescence PCR method used for hepatitis b virus （HBV） detection is 100.0%. 122 cases are negative according to gold stand ard test. In the 121 cases, result of 121 cases by fluorescence method of PCR test were negative. The specificity of fluorescence PCR method used for hepatitis b virus （HBV） detection was 99.18%. Fluorescence PCR method used for hepatitis b virus （HBV） points of the type testing a pre dictive accuracy of 100% for the parting. No statistical difference was found by 4 cases table chi square fluorescence PCR method and the method of the gold standard of classification test results. Conclusion Fluorescent PCR method has high sensitivity, high specificity, prevention pollution ability strong, high degree of automation, speed and other advantages, suitable for infectious disease monitoring and clinical use of hepatitis B virus （HBV） in the parting fast detection.
