Abstract

Background

The landscape of diagnostic assays for detecting herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) antibodies (IgG) has evolved over time. This study aims to evaluate the analytical performance of Alinity-i chemiluminescence immunoassays in detecting specific anti-HSV-1 and HSV-2 IgG.

Methods

A retrospective analysis was conducted on 157 serum samples collected from 155 patients between June 2023 and July 2024. Three assays were compared: Alinity® HSV-1 and HSV-2 IgG (Abbott), Liaison® HSV-1 and HSV-2 Type Specific IgG (Diasorin), and BioPlex® 2200 HSV-1 & HSV-2 IgG (Bio-Rad). Results were interpreted based on index values. The Anti-HSV-1/HSV-2-gG2 EUROLINE Western blot was used to provide definitive conclusions in cases of discordant results.

Results

The sensitivities and specificities of the Alinity-i assays were respectively 98 % and 100 % for HSV-1 IgG and 92 % and 98 % for HSV-2 IgG. The interpretation concordance among the three assays was high with Cohen's kappa values ranging from 0.82 to 0.90. Of the 27 discordant samples, Western-blot analysis identified false negatives as follows: 2 and 14 for Liaison, 3 and 5 for Alinity-i, and 2 and 0 for BioPlex, for HSV-1 and HSV-2 IgG respectively. Additionally, Western Blot revealed false positives in 3 Liaison and 1 BioPlex sample for HSV-1, and in 1 Liaison and 2 Alinity-i samples for HSV-2.

Conclusion

The Alinity-i HSV-1 and HSV-2 IgG serology demonstrated excellent sensitivities and specificities compared to Liaison and BioPlex assays. These findings underline the efficacy of Alinity-i in clinical diagnostics, suggesting it as a reliable tool for HSV-1 and HSV-2 antibody detection in diverse patient populations.

期刊介绍： The Journal of Clinical Virology, an esteemed international publication, serves as the official journal for both the Pan American Society for Clinical Virology and The European Society for Clinical Virology. Dedicated to advancing the understanding of human virology in clinical settings, the Journal of Clinical Virology focuses on disseminating research papers and reviews pertaining to the clinical aspects of virology. Its scope encompasses articles discussing diagnostic methodologies and virus-induced clinical conditions, with an emphasis on practicality and relevance to clinical practice. The journal publishes on topics that include: • new diagnostic technologies • nucleic acid amplification and serologic testing • targeted and metagenomic next-generation sequencing • emerging pandemic viral threats • respiratory viruses • transplant viruses • chronic viral infections • cancer-associated viruses • gastrointestinal viruses • central nervous system viruses • one health (excludes animal health)
