Important things to note if you test positive for hepatitis C

What does a positive hepatitis C antibody test mean? A positive result on a hepatitis C antibody test indicates that hepatitis C antibodies were detected in the specimen tested. This result is consistent with a current infection, or a past infection that has resolved, or a biologic false positivity for hepatitis C antibody (1). What are the next steps? Consult with a health care professional for follow up testing for hepatitis C nucleic acid (RNA). The detection of hepatitis C RNA utilizes a different lab technique compared to the detection of hepatitis C antibodies. If hepatitis C RNA is not detected, it indicates a past hepatitis C infection that has resolved, and generally no further action or treatment is required. It is estimated that up to half of all infected individuals are able to spontaneously clear hepatitis C after an acute infection (2). If hepatitis C RNA is detected, it indicates a current hepatitis C infection. Generally an additional test for hepatitis C RNA is recommended to confirm a current infection before any treatment protocols begin (3). Management and treatment of an active hepatitis C infection Appropriate counseling, care and treatment will be organized by the health professional who requested the hepatitis C RNA test (4). Management and treatment options may include:
  • Medical evaluation for chronic liver disease
  • Vaccinations for hepatitis A and hepatitis B (no vaccines are available for hepatitis C)
  • Screening for and control of alcohol consumption
  • HIV testing
  • Direct acting antivirals to limit the replication of the hepatitis C virus and slow the progression of the disease
  • Following a healthy diet and staying physically active
  • Consultations before taking any new prescriptions, medications or supplements (to prevent further potential liver damage)
  • Avoid donating blood, tissue, or semen
  • Covering of cuts and sores to prevent transmission of hepatitis C
