Objective:
To present a brief review of the diagnostic benefits of quantitating viral load for hepatitis C and how the reverse transcriptase polymerase chain reaction is being used as an aid to better diagnose and manage the disease.
Data Source:
Research articles about hepatitis C and the reverse transcriptase polymerase chain reaction, as well as data gathered by the authors.
Study Selection:
Performed by the authors.
Data Extraction:
Performed by the authors.
Data Synthesis:
Hepatitis C viral infection is a worldwide health problem, affecting about 100 million people worldwide. Numerous serological tests exist to detect antibodies to hepatitis C antigens, but some affected people fail to generate an immune response. Reactivity in the reverse transcriptase polymerase chain reaction is definitive proof of hepatitis C infection. The titer of RNA indicates patient response to antiviral therapy. Measuring the presence and quantity of RNA by the reverse transcriptase polymerase chain reaction has become an important aid for diagnosis and monitoring of hepatitis C infection.
Conclusion:
The reverse transcriptase polymerase chain reaction method is a highly sensitive and accurate aid in diagnosing or confirming diagnosis of hepatitis C viral infection. This method is widely used to assess likelihood of patient response to therapy, and to monitor efficacy during therapy.
