Introduction
High-sensitivity DNA testing may be required in the diagnosis of diseases such as chronic hepatitis B and liver cirrhosis. High-sensitivity DNA testing is highly sensitive to hepatitis B virus (HBV) DNA and can help doctors determine whether a patient has chronic hepatitis B. For some patients with previously positive results on standard DNA testing who continue to show abnormal liver function or signs suggestive of cirrhosis, high-sensitivity DNA testing may also be recommended.
When diagnosing diseases such as chronic hepatitis B and liver cirrhosis, a high-sensitivity DNA test may be required. The specific analysis is as follows:
The high-sensitivity DNA test can detect lower levels of viral load and is primarily a method for detecting hepatitis B virus (HBV) DNA. Due to its high sensitivity, it is now widely used in clinical practice. In some patients, standard DNA testing may yield negative results, yet liver function tests might show recurrent abnormalities or signs suggestive of cirrhosis. In such cases, patients may undergo high-sensitivity DNA testing as directed by their physician to determine the exact HBV DNA level and assess whether further treatment is necessary.
The high-sensitivity DNA test requires a venous blood sample. However, patients should also undergo liver function tests at the time of examination, which require fasting.
