Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In China, there is no recommendation for Hepatitis D virus (HDV) screening, but the fact is estimated that one-third of the world's population of individuals with chronic Hepatitis B virus (HBV) infection live in China while we do not know the prevalence of co-infection of HBV/HDV in China. So far, no nationwide study has been undertaken to evaluate the epidemiology of hepatitis D, on the other hand, reports of HDV infection rate in different regions of China are not consistent because of the different detection methods and detection objects. Here, we plan to test HDV-Ab/RNA for 5000 HBsAg reactive samples from 10 major tertiary hospital and to know the prevalence and disease burden of HDV in China.

HDV-Ab (IgG), HDV-RNA, RNA genotype

Anti-HDV was evaluated semiquantitatively by means of end-point dilutions. Quantitative HDV-RNA was performed by means of LightCycler 2.0. Genotyping of HDV was performed by direct sequencing of the delta antigen region.
