Hepatitis B is viral hepatitis, which is one of the most common critical liver infections in the world. Hepatitis B is caused by the hepatitis B virus (HBV), and the HBV attacks the liver triggering inflammation that can set off liver damage that can cause cirrhosis, liver cancer, and even death.
Structure of the Hepatitis B Virus
The hepatitis B virus contains an external shell and an internal nucleus.
The external envelope of the virus consists of a surface protein called hepatitis B surface antigen or "HBsAg". The HBsAg can be detected through a blood test , HBsAg-positive test result indicates someone is infected with HBV.
The internal nucleus of HBV is a protein shell known as the hepatitis B core antigen or "HBcAg," which contains the HBV DNA and enzymes used in the replication of the viral.
Hepatitis B infection can be divided into acute hepatitis B and chronic hepatitis B..
Acute Hepatitis B
Acute hepatitis B is a short-term disease condition that occurs in the first six months of exposure to HBV. Certain individuals with acute hepatitis B may be asymptomatic or mildly ill. In some cases, acute hepatitis B may cause liver failure and a more serious illness that requires hospitalization.
Chronic Hepatitis B
Chronic hepatitis B. (Chronic means long-lasting over six months.), which leads to inflammation, cirrhosis, and liver cancer and is possibly fatal.
Accurate diagnosis is vital to control hepatitis B infection. Quantification Hepatitis B virus (HBV) DNA plays a critical role in the management of HBV infections. PCR-based assays are the most widely used method for HBV DNA quantification. A sensitive and accurate HBV DNA quantification assay is essential for monitoring hepatitis B virus (HBV) replication.
Here are the Steps for HBV DNA Quantitative Detection:
Blood sampling for detection of hepatitis B virus DNA
Detecting the hepatitis B virus DNA
Observe the viral load. If the viral load is high, it indicates the HBV is actively replicated in the patient's body.
