| Antibody positive, HCV RNA positive | There is currently an active infection |
| Antibody negative | No infection or no antibodies produced in the early stage of infection |
2. Clinical significance of hepatitis C antibody positivity
1.Previous infection:If the antibody is positive but HCV RNA is negative, it may mean that the infection has been resolved or the virus has been cleared through treatment.
2.Current infections:If both antibodies and HCV RNA are positive, the degree of liver damage needs to be further evaluated and antiviral treatment required.
3.False positives may:In some cases (such as autoimmune diseases), false positive results may occur and need to be confirmed with other tests.

6. Summary
A positive hepatitis C antibody is not a disease diagnosis in itself and needs to be combined with viral nucleic acid testing for comprehensive judgment. As medical technology advances, hepatitis C has become a curable disease. The key is to stay calm after discovering a positive result and seek medical treatment in a timely and standardized manner. It is recommended that high-risk groups (such as those who received blood transfusions before 1992, intravenous drug addicts, etc.) proactively undergo screening to achieve early detection and early treatment.
