Dectection of TTV in hepatitis patients

Objective: To study the prevalence of transfusion transmitted virus (TTV) in hepatitis patients. Methods:Sera from hepatitis patients were tested by nested polymerase chain reaction (nPCR) assay for the presence of TTV DNA. Results:The total detection rate of TTV DNA in those 218 objects was 33.0%. The TTV positive rate was 53.9% in non A E hepatitis, but 26.5 % in hepatitis patients whose diagnosis were clear. There was no relationship between TTV infection with nationalities、sex of hepatitis patients. Conclusion: TTV infection may be one of the cause of non A E hepatitis.
