Abstract

The present invention relates to a method for quantifying hepatitis B virus DNA (HBA-DNA) by means of the PCR hybridization process, and to primers and probes used for such method. The present invention also relates to a kit for detecting HBV-DNA comprising said primers and probes. Specifically, the present invention is characterized in that said HBV is either an adr sub-type or an adw sub-type.

Description

technical field [0001] [1] The present invention relates to a method for quantifying hepatitis B virus (HBV) through a PCR hybridization process, and also relates to primers and probes used in the quantification method. The invention also relates to an HBV-DNA detection kit comprising the primer and probe. Background technique [0002] [2] Hepatitis B virus (HBV) is a virus from the family Hepadnaviridae that specifically acts on the human body. It is understood that about 500 million people in the world are infected with HBV. The incubation period of HBV is 60 to 110 days. After varying levels of clinical cycles, 90-95% of patients infected with HBV fully recover, but for patients who do not recover from infection, HBV genomic DNA is inserted and integrated into the patient's stem cell genomic DNA until it develops into Chronic active hepatitis, liver cirrhosis, liver cancer, etc. Like other diseases, HBV infection can cause chronic viral infection disease lymphadenoma ...
