Hello, generally speaking, the reference value of the normal value of the quantitative detection of hepatitis B virus is 1.0* 10 to the third power. The results of the quantitative detection of hepatitis B virus DNA have a great relationship with hospitals and hospital equipment. Generally speaking, it is believed that the value of hepatitis B virus DNA is 3-5 power, which means that the virus is replicating in a low amount and its infectivity is weak. If it is 5-7 power, it means moderate replication, which is relatively contagious; If the DNA of hepatitis B virus is greater than the 7th power, it means that hepatitis B virus replicates in a large number in the body and is highly contagious. Moreover, the larger the number, the stronger the infectivity.
