Résumé
<p><b>OBJECTIVE</b>To detect HBV-LP and HBV DNA of the patients with hepatitis B, and to study the sensitive and specificity of HBV-LP detecting and its evaluate on for clinical application.</p><p><b>METHODS</b>The ELISA was used for HBV-LP detecting and RT-PCR for HBV DNA detecting.</p><p><b>RESULTS</b>The sensitive and specificity of HBV-LP and HBV DNA were 64.89%, 99.68%, 60.63% and 100% respectively (P > 0.05); +LR, -LR were 202.78, 60.63, 0.3522 and 0.3937, and there were significance between +LR of the detecting (P < 0.005).</p><p><b>CONCLUSION</b>The sensitive and specificity of HBV-LP and HBV DNA detecting are considerable, +LR of HBV-LP are higher comparing HBV DNA. The HBV-LP is better serology index for detecting replication of HBV DNA.</p>
