Brief Summary

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

Atni-HBs to HBsAg and Anit-HBc was interpreted based on three hepatitis markers for clinical detection of HBV-infections. HBAg and Anti-HBs were negative and the Anit-HBc-positive referred to as Anti-HBc alone. When the Anti-HBc alone occurs, patients may be due to mutations in HBV HBsAg can not be detected due to (1), but if by the molecular diagnostics by polymerase chain reaction (PCR) technology can detect HBV DNA present. When Anti-HBc alone in patients with serum HBV DNA can be measured, then there may be occult HBV infection. In different countries, Occult HBV infection in the Anti-HBc Alone group had significant differences in the prevalence (2.9 \~ 22.8%) (2), but prevalence survey in Taiwan there are very few studies on this , It is hoped to be able to investigation the prevalence of occult HBV infection Among Anti-HBc Alone.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main use of this program, Taipei Medical University - Wan Fang Hospital in clinical specimens using the Roche system (Corbas e601) operating HBsAg, Anti-HBs, Anti-HBc to screen for the Anti-HBc alone group. Recycling Roche molecular system (Taq48) Real-time PCR to detect all anti-HBc alone population to understand their serum HBV-DNA viral load, in order to understand Occult HBV infection in the Anti-HBc alone group, the prevalence and viral load changes in these studies through the clinical units to provide occult HBV infection as a reference basis.
