Insights
Detecting hepatitis C virus (HCV) core antigen offers significant clinical value as a supplemental test for HCV infection diagnosis, especially when anti-HCV tests are inconclusive.
Area of Science:
- Virology
- Immunology
- Diagnostic Medicine
Context:
- Hepatitis C virus (HCV) infection remains a significant global health concern.
- Accurate and timely diagnosis is crucial for effective patient management and treatment.
- Current diagnostic methods, such as anti-HCV antibody testing, may have limitations in certain clinical scenarios.
Purpose:
- To evaluate the clinical utility of detecting hepatitis C virus core antigen (HCVcAg) as a diagnostic marker for HCV infection.
- To compare the detection rates of HCV core antigen with HCV-RNA and anti-HCV antibodies.
- To assess the role of HCVcAg testing as a supplemental tool alongside conventional serological markers.
Summary:
- The study analyzed 191 patients, with positive rates of 71.2% for HCV-RNA, 97.4% for anti-HCV, and 33.0% for HCV core antigen.
- Notably, HCV core antigen was detected in patients negative for both HCV-RNA and anti-HCV post-therapy, and in one patient with a negative anti-HCV result.
- These findings highlight the potential of HCV core antigen detection in specific diagnostic situations.
Impact:
- HCV core antigen detection can serve as a valuable supplemental diagnostic marker for HCV infection.
- It may improve diagnostic accuracy in cases where standard anti-HCV testing is negative or equivocal.
- Integrating HCV core antigen testing could enhance the early detection and management of hepatitis C.
Aim:
To explore the value of detecting hepatitis C virus core antigen in HCV infected diseases.
Methods:
The HCV-RNA was tested by fluorescent quantitative polymerase chain reaction (FQ-PCR). The core antigens of HCV and anti-HCV were tested by enzyme-linked immunosorbent assay (ELISA).
Results:
The positive rate of HCV-RNA in 191 patients was 71.2%, about 136 in 191. The positive rate of anti-HCV was 97.4%, about 186 in 191. The positive rate of HCV core antigen was 33.0%, about 63 in 191. After antiviral therapy for 2 patients,their HCV-RNA and anti-HCV were detected negative but their HCV core antigen was detected positive. In another patient, his anti-HCV was negative but his HCV core antigen was positive.
Conclusion:
As a supplemental test for anti-HCV examination the detection of HCV core antigen is of important clinical value in HCV infection diagnosis.

Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
