Your Testing Pattern Indicates a False-Positive Antibody Result—No Further Action Is Required
Based on your testing sequence (negative HCV RNA followed by a subsequent negative antibody test with normalized liver enzymes), you most likely had a false-positive antibody result and do not have hepatitis C infection. 1, 2
Understanding Your Test Results
Your specific pattern is highly reassuring:
- A positive HCV antibody test followed by negative HCV RNA definitively indicates no current HCV infection, according to the most recent AASLD-IDSA guidelines from 2020 1
- The subsequent negative antibody test two months later strongly suggests the initial positive was a false-positive result, as true HCV antibodies typically persist for life even after viral clearance 2, 3
- False-positive antibody results occur in approximately 22-35% of reactive tests in populations with low HCV prevalence, making this a common scenario 4, 5
- Your normalized ALT and AST further support the absence of active liver inflammation or infection 6, 7
Why No Further Testing Is Needed
The 2020 AASLD-IDSA guidelines explicitly state that when HCV antibody is reactive but HCV RNA is not detected, no further action is required in most cases 1, 3:
- You had confirmatory RNA testing that was negative, which is the gold standard for ruling out active infection 1, 8
- Your follow-up antibody test reverted to negative, which would not occur with true resolved infection (antibodies persist lifelong after true infection) 2, 3
- Your liver enzymes normalized, providing biochemical evidence of no ongoing hepatocytic injury 6
The Only Exceptions Requiring Repeat Testing
You would need repeat HCV RNA testing ONLY if any of these apply 1, 2, 3:
- Recent HCV exposure within the past 6 months (during the window period, RNA may be transiently negative) 1, 2
- Clinical signs of active liver disease (jaundice, hepatomegaly, persistent elevated liver enzymes) 2, 3
- Immunocompromised status (HIV infection, organ transplant, chemotherapy) where antibody tests may be unreliable 1
- Ongoing high-risk exposures (active injection drug use, occupational needlestick injuries) 1, 2
What This Means for You
- You do not have hepatitis C infection and do not need treatment 1, 3
- You are not infectious to others 1, 3
- You do not need isolation precautions or lifestyle modifications related to HCV 3
- If you had true past infection that resolved (unlikely given your negative follow-up antibody), you could be reinfected if exposed again, as HCV antibodies do not provide protective immunity 3
Common Pitfalls to Avoid
- Do not misinterpret a single positive antibody test as definitive evidence of infection without RNA confirmation—this is why RNA testing is mandatory after positive antibody results 1, 9
- Do not assume you need ongoing monitoring or specialist referral unless you have the specific risk factors listed above 1, 2
- Do not undergo unnecessary repeat antibody testing unless new exposure occurs, as this can lead to confusion and anxiety 2, 3
