How is the hepatitis B virus quantified?

Patient's question:

Hepatitis B Virus Nucleic Acid Quantification by Fluorescence (Taqman method) 4.19×10~7 Reference value <500 copies/ml

Doctor's answer:

This is a nucleic acid test for the hepatitis B virus, indicating the presence of hepatitis B virus infection. It represents the amount of hepatitis B virus copies, which is 4.19 divided by 10 to the 7th power, equivalent to 41,900,000. The normal reference range is below 500, so the hepatitis B virus copies are highly active and highly infectious. High levels of hepatitis B virus can cause damage to liver cells. Therefore, it is necessary to visit the infectious disease department for medical evaluation, including liver function tests and abdominal ultrasound, to receive antiviral treatment and close monitoring.
In addition to treating liver disease, it is recommended that patients pay attention to their diet in daily life and maintain a positive mood to enhance their physical condition and accelerate recovery.
