Hepatitis B dna hypersensitivity below 10iu/ml is relatively safe and can greatly reduce the risk of cirrhosis and liver cancer. The lower limit of the hepatitis B dna high-sensitivity test is around 10iu/ml. If the hepatitis B dna high-sensitivity test suggests less than 10iu/ml, it means that the virus is at a very low level in the body of the person being tested. This situation is usually the result of virus suppression after taking antiviral drugs, indicating very good virus control. The effect of the virus on the liver is minimized in this case, greatly reducing the risk of cirrhosis and liver cancer. Hepatitis B dna high-sensitivity test below 10iu/ml should also be maintained for regular review. Once the hepatitis B dna is found to be elevated, it is an indication that drug resistance or decreased drug sensitivity may have occurred, and one should visit a specialist to have the medication changed in a timely manner.
