Detailed Description
Hepatitis C virus (HCV) infection is a major public health burden, with an estimated 71 million patients being infected globally. If undiagnosed, HCV infection can lead to severe liver damage, including hepatocellular carcinoma (HCC). The World Health Organization (WHO) recently set a target to eliminate HCV by 2030. The first critical step in reaching this target is to accurately identify people infected with HCV. Globally, significant gaps remain in diagnosis of HCV, with four out of five people infected still unaware of their status, largely due to lack of access to testing services.
In resource-limited settings (RLS), laboratory-based testing remains a mainstay for HCV screening and confirmatory testing. Such laboratory-based assays rely on transportation of temperature-sensitive samples from clinic sites to centralized laboratories, high-tech equipment and highly skilled laboratory technicians, limiting the scope of access to testing and resulting in long turn-around times for results. In recent years, new technologies have been developed to decentralize HCV screening and confirmatory testing using point-of-care (POC) assays to overcome these barriers and improve patient outcomes.
Rapid diagnostic tests (RDT) for screening for HCV are affordable, accurate, easy to use by healthcare workers, and robust in field settings. Although a number of HCV RDTs are on the market, currently only two have received WHO pre-qualification (PQ) status, demonstrating their accuracy and reliability for use in the field in RLS. Data on a number of other RDTs indicate their suitability for use. More data is needed, however, in field settings for these HCV RDTs, to demonstrate their accuracy and quality in end-user studies and to provide evidence for WHO PQ approval.
Based on the results of a recent FIND laboratory evaluation assessing the performance of 13 HCV RDTs using archived plasma samples, we have selected three candidate HCV RDTs ("study RDTs") for further evaluation in field settings (e.g. primary healthcare facilities). The performance of these RDTs measured in frozen plasma specimens indicated that they have a high potential to meet WHO PQ performance criteria in freshly collected samples. In addition, the manufacturers each demonstrate evidence of engagement to pursue both CE-mark status and the WHO PQ process, showing commitment to delivering quality-assured tests to the market.
The data generated during this study will be used to inform national and international stakeholders on HCV RDT performance in field settings and shared with manufacturers to support the evidence package for WHO PQ and/or CE-marking.

Fingerstick whole blood, plasma and serum of each participant is tested with three investigational HCV RDTs and one reference HCV RDT.
Plasma is also used for testing with the composite reference standard, HCV viral load and genotyping.
All participants are also tested for HIV with an HIV RDT.
