Introduction

If liver disease is suspected but it is unclear whether it is hepatitis A, B, or C, a series of tests are needed to determine the cause. Common tests include hepatitis C virological testing, hepatitis B virological testing, and liver biopsy. The specific tests required depend on the individual patient's condition, and it is recommended to undergo testing under the guidance of a physician.

If liver disease is suspected but it is unclear whether it is hepatitis A, B, or C, a series of tests are needed to determine the underlying cause. Common diagnostic procedures include hepatitis C virological testing, hepatitis B virological testing, and liver biopsy. Details are as follows:

1. Hepatitis C Virological Testing

In hepatitis C virological testing, indicators such as antibodies against the hepatitis C virus can be detected to confirm whether a person has been infected with the hepatitis C virus. If the test result is negative, hepatitis C infection can be ruled out, but further testing is still required to determine if infection with other types of hepatitis viruses exists.

2. Hepatitis B Virological Testing

This includes markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B e-antigen (HBeAg), and hepatitis B e-antibody (anti-HBe), which help determine whether a person has been infected with the hepatitis B virus.

3. Liver Biopsy

By removing a small sample of liver tissue for pathological examination, this procedure can identify whether there are liver abnormalities such as inflammation, fibrosis, or liver cancer.

In addition, liver function tests and liver biopsy can also help differentiate between hepatitis A, B, and C. All tests should be performed under the guidance of a physician.

The above-listed tests are common diagnostic options. The specific tests required may vary depending on individual patient circumstances. It is recommended that all testing be conducted under the guidance of a healthcare professional.
