Article Abstract
Background: Hepatitis C virus antibody (anti-HCV) test had been approved as a preliminary screening test for HCV infection. Light-initiated chemiluminescent assay (LiCA) was a homogenous method. We aimed to assess the clinical diagnostic performance of LiCA and compare it with that of chemiluminescence immunoassay (CLIA) which was widely used in clinical laboratories.
Methods: A total of 10 772 patients from the Peking University Third Hospital were enrolled. The serum samples were detected on the ChIVD LiCA500 and Abbott Architect i2000SR platforms. Recombinant immunoblot assay (RIBA) and HCV RNA assay were used for confirmation.
Results: The negative agreement rate between ChIVD LiCA anti-HCV assay and Abbott Architect anti-HCV assay was 99.91%, the positive agreement rate was 37.31%, the total agreement rate was 98.74%, and the kappa coefficient (κ) was 0.519. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ChIVD LiCA anti-HCV assay were 96.39%, 99.95%, 89.58%, and 99.97%, respectively, which were superior to those of Abbott Architect anti-HCV assay (93.98%, 99.25%, 51.90%, and 99.95%, respectively).
Conclusion: ChIVD LiCA anti-HCV assay was a highly sensitive, specific homogenous method with good diagnostic performance, and was applicable for the routine screening of HCV infection in clinical laboratories.

Aim: Hepatitis C virus (HCV) infection remains a global health concern. Although the World Health Organization (WHO) proposed a strategy to eliminate HCV by 2030, Japan faces challenges owing to limited access and insufficient support for high-risk populations. Previously, HCV diagnoses required a two-step process, delaying results and increasing costs.

Rapid point-of-care tests for hepatitis C virus (HCV) provide results in 20 min and allow linkage to care, particularly for difficult-to-reach populations. Prior work suggested an early reading time of the OraQuick (OQ) rapid HCV antibody lateral flow immunoassay identified people with HCV viremia; however, these observations were not externally validated. We conducted a prospective cohort study at Penn Presbyterian Medical Center from June 2021 to August 2023 to evaluate the performance of OQ early reading times for HCV viremia among participants with reactive HCV antibody.

Background: Blood transfusions save millions of lives each year, but are also associated with significant health risks, including transfusion-transmitted infections (TTIs). The World Health Organization recommends mandatory screening for human immunodeficiency virus (HIV), hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), and syphilis prior to transfusion. This study presents the first screening results from a public blood bank in Somaliland.

Objective: In this study, we aimed to analyze the blood screening detection strategies employed for voluntary blood donation in a specific region of East China and evaluate the efficacy of the blood safety detection system.
Donors And Methods: A total of 539,117 whole blood samples were collected from voluntary blood donors between January 2018 and July 2021, as well as in 2023 and 2024. The samples were screened for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies, human immunodeficiency virus antibodies/antigen (HIV Ab/Ag), and Treponema pallidum (TP) antibodies using enzyme-linked immunosorbent assay (ELISA).
