The abbreviation for hepatitis B virus is HBV, so the test is often written as “HBV-DNA”, which is also known as genetic diagnosis, and is most commonly used today as the “PCR method”. It is called: polymerase chain reaction. This method uses special instruments to amplify a very small amount of DNA by a factor of a million, and is therefore very sensitive. The diagnostic value of HBV-DNA quantitative test by fluorescence quantitative PCR method: 1, HBV-DNA quantitative test by fluorescence quantitative PCR method before treatment, you can choose the targeted drugs to avoid blind medication. 2, fluorescence quantitative PCR method HBV-DNA detection after treatment quantitative PCR can directly and accurately determine the number of viruses in the body, which helps to determine the effectiveness of the treatment of hepatitis B 3, fluorescence quantitative PCR method HBV-DNA detection quantitative PCR measurement before pregnancy, which helps to select a beneficial pregnancy opportunity. Quantitative PCR test for women during pregnancy of hepatitis B helps to make timely and correct diagnosis for some patients. The reduction of HBV-DNA quantitative test index by fluorescent quantitative PCR has a very important significance in the administration of hepatitis B. It is the prelude to the conversion of hepatitis B, or the most critical step in recovery, and only when the quantitative index of HBV-DNA in the body is reduced, the clonal reproduction of the virus will be terminated and there is hope for the eradication of hepatitis B. The normal value of HBV DNA is <10 to the third power (or <1.0e+03 copies /ML is the normal value, this value is for reference only, subject to the data of the testing hospital). Whether the HBV-DNA is positive or negative, it only represents the replication and infectiousness of the hepatitis B virus, and there is no direct relationship between the amount of HBV-DNA value and the degree of liver damage.

Whether the HBV-DNA is positive or negative, it only represents the replication of the hepatitis B virus and the strength of infectiousness, and there is no direct relationship between the amount of HBV-DNA value and the degree of liver damage.
