The eight immune tests include the five indicators of hepatitis B, hepatitis C antibodies, syphilis antibodies and HIV antibodies. The clinical significance of the tests for these antibodies varies. If the five indicators of hepatitis B suggest major or minor triplets, further liver function and hepatitis B DNA tests are required to assess the condition. If hepatitis C antibodies, syphilis antibodies, or HIV antibodies are positive, further confirmatory tests are needed. These initial screenings are inaccurate and there is a possibility of false positives, and only if the confirmatory tests are also positive can the infection be clearly diagnosed as these diseases. Of course, the current treatment for the disease differs according to the cause of the disease. Hepatitis B and C are mainly treated with antiviral therapy, while syphilis is mainly treated with syphilis repellent, and for AIDS, lifelong antiviral medication is required.
