Tests for hepatitis C mainly include hepatitis C core antigen, hepatitis C antibody, ribonucleic acid of hepatitis C virus and gene sequencing, the main analysis is as follows: 1. Hepatitis C core antigen: it is an indicator for diagnosing early hepatitis C infection and can improve the detection rate of window period infection. 2. Hepatitis C antibody: it is the main indicator for diagnosing viral hepatitis C. The window period after infection with hepatitis C is long, usually 2-6 months after the onset of the disease, some even The window period after infection with hepatitis C is long, usually 2-6 months after the onset of the disease, and some even two years after turning positive, so it cannot be used as a method of early diagnosis. The positive hepatitis C antibody cannot distinguish between previous infection and current infection and cannot be used for the observation of antiviral efficacy. 3. Hepatitis C ribonucleic acid: it is the genetic material of hepatitis C and is a direct indicator of hepatitis C infection in the body, which can be used for the early diagnosis of hepatitis C infection and the observation of the efficacy of antiviral therapy. 4. Gene sequencing: genotyping of hepatitis C virus genes to The genotyping of the hepatitis C virus to improve the personalization and targeting of antiviral therapy. The correct application of the test can be used to understand the various conditions of hepatitis C disease.”
