If the hepatitis B dna is less than 500cps/ml, then it means that the replication of the hepatitis B virus in the body is slower, but it is not certain that there is nothing wrong, and it needs to be combined with the results of the liver function test to make a judgment. Generally speaking, the normal value of hepatitis B dna is 1000cps/ml, if the actual detection value of hepatitis B dna is less than 500cps/ml, then it means that the body of hepatitis B dna is negative, the replication of the hepatitis B virus is very slow, the infectiousness is relatively weak or no infectiousness, the majority of patients have a good state of health, but it does not mean that there is no matter. In this case, most of the patients are hepatitis B virus carriers, although there is no need for special treatment, but still need to carry out further liver function tests. If the liver function is normal, no treatment is needed for the time being. However, if the liver function is abnormal, then it indicates that there may be hepatitis problems, and antiviral treatment is needed under the guidance of a doctor, of which commonly used drugs include entecavir tablets as well as tenofovir disoproxil fumarate tablets and so on. In normal times, patients should strengthen the protection of the liver, pay attention to diet, eat less spicy, stimulating food, drink more water, maintain healthy sleep habits, and go to the hospital regularly for review, so as to avoid deterioration of the condition.
