Hepatitis C testing issues?


Hello, doctor.
I recently underwent a self-paid health check (anti-HCV) and was notified by the hospital that I have a positive reaction for hepatitis C.
Does this mean that I am definitely infected with hepatitis C? Should I inquire about the concentration to determine the possibility of a false positive? Or do I need to undergo HCV-RNA testing to confirm?

If the hepatitis C virus has not been treated, an RNA test will be conducted.
If the RNA test is positive, treatment is essential.

When you receive a positive anti-HCV (antibody to Hepatitis C virus) test result, it can understandably cause a lot of concern and anxiety. However, it is important to understand what this result means and the next steps you should take.

Firstly, a positive anti-HCV test indicates that you have been exposed to the Hepatitis C virus at some point in your life. It does not necessarily mean that you currently have an active Hepatitis C infection. In fact, about 15-45% of individuals who are infected with Hepatitis C will clear the virus spontaneously without any treatment, leaving them with only the antibodies present in their blood. This is often referred to as a "resolved infection."
To determine whether you have an active infection, the next step is to perform an HCV RNA test. This test detects the actual virus in your blood and can confirm whether you are currently infected. If the HCV RNA test is negative, it suggests that you do not have an active infection, and you may have cleared the virus on your own. If it is positive, it indicates that you have an active Hepatitis C infection, and further evaluation and treatment may be necessary.

Regarding the concern about false positives, it is indeed possible for anti-HCV tests to yield false-positive results. Factors such as cross-reactivity with other antibodies or technical errors in the testing process can lead to such outcomes. Therefore, if you have a positive anti-HCV result, it is standard practice to follow up with an HCV RNA test to confirm the presence of the virus.

In summary, here are the steps you should take following a positive anti-HCV test:
1. Get an HCV RNA Test: This will help determine if you have an active Hepatitis C infection. If the result is negative, you likely do not have an active infection.

2. Consult with a Specialist: If your HCV RNA test is positive, it is advisable to consult with a healthcare provider who specializes in liver diseases or infectious diseases. They can provide you with information about treatment options and the implications of your diagnosis.

3. Consider Additional Testing: Depending on your situation, your healthcare provider may recommend additional tests, such as HCV genotype testing, which can help determine the specific strain of the virus and guide treatment decisions.

4. Monitor Your Health: Regardless of the outcome, it is essential to maintain regular check-ups with your healthcare provider to monitor your liver health and overall well-being.

5. Educate Yourself: Understanding Hepatitis C, its transmission, and management can help alleviate some of the anxiety associated with the diagnosis. Resources from reputable health organizations can provide valuable information.

Lastly, it is crucial to remember that Hepatitis C is a manageable condition, and with appropriate medical care, many individuals can lead healthy lives. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for guidance and support.
