The present study aims to establish a " one-sample testing platform " and assess the prevalence of hepatitis C in individuals taking routine physical examination or outpatient visit in mainland China.
Investigators intend to establish a one-sample testing platform to improve diagnosis and linkage to care process in participants under routine physical examination or outpatient visit. The platform is based on rapid diagnostic tests (RDTs) for HCV screening and HCV core antigen for confirmation. RDTs was used to screen for anti-HCV antibodies. The result of RDT will be interpreted within 15 minutes with the sensitivity of 98.9% (95%CI, 94.5% to 99.8%) and specificity of 98.9% (95%CI, 97.5% to 99.9%) using whole blood or finger-stick blood sample \[3-5\]. HCV core antigen is a marker of HCV replication and has a good correlation with HCV RNA in HCV-positive patients (R=0.98). A recent study suggested HCV core antigen testing could be used alternative testing for HCV RNA testing for diagnosis when HCV RNA testing was unavailable. The process of HCV core antigen test only takes 2-3 hours. "one-sample" means only one drop (10ul) of finger-stick blood or residual blood samples from other routine tests collected from patients was needed for anti-HCV antibody testing and HCV core antigen testing, which means they will not have to take another venepuncture. In addition, the use of RDT and HCV core antigen are also less costly. This approach might improve access to care, particularly in low-income and middle-income countries. The present study aims to establish a " one-sample testing platform " in several medical institution to assess the prevalence of hepatitis C in individuals taking routine physical examination and further promote rapid diagnosis platform in mainland China, so as to achieve the goal in 2030.
Study Type
OBSERVATIONAL
Enrollment
20,000
HCV antibody screening were carried out with rapid diagnostic testings (RDTs) by colloidal gold method, using fingertip blood or residual blood from other testings. For samples with positive HCV antibody RDTs screening results, HCV core antigen detection will be carried out subsequently as diagnostic test. HCV core antigen detection will be conducted with chemiluminescent particle immunoassay using residual blood from other testings.

The prevalence of HCV infection
The prevalence of HCV infection in the population attending each center (including physical examination)
Time frame: 1 day
The proportion of abnormal fibroscan results, liver function, blood routine, and ultrasound data in HCV-infected people
For example, the confirmed rate of HCV infection in the screening population was much higher than that of HCV infection in the region in the epidemiological survey, and the degree of liver fibrosis and cirrhosis assessed by the confirmed population through this process was significantly lower than the mean HCV population reported in the literature, which indirectly reflected the potential benefit of rapid diagnosis process in helping to detect HCV infection missed in routine visits (including physical examination).
