How Do We Test for Hepatitis C?
Published: Oct 07, 2023
Detecting hepatitis C virus requires sophisticated diagnostic tests due to its complex nature. Learn about the testing methods that help identify this elusive virus.
HCV Diagnostic Challenges
Testing for HCV is complicated by its genetic diversity and the presence of quasispecies. Diagnostic tests focus on the virus's conserved regions to ensure accuracy and reliability, despite the virus's tendency to mutate.
Types of HCV Tests
Common tests include antibody tests to detect past exposure and RNA tests to find current infections. RNA tests target stable parts of the virus's genome, providing a clear picture of active infection even amidst its diversity.
Interpreting Test Results
Positive antibody tests indicate past exposure but not necessarily current infection. RNA tests confirm active infection, guiding treatment decisions and helping monitor the effectiveness of interventions.
Frequently Asked Questions
