However, conventional Limiting Antigen Avidity Enzyme Immunoassays (LAg-EIAs) are restricted to laboratory settings. A novel rapid recency test based on the limiting antigen avidity principle was developed for point-of-care use. We evaluated the performance of the rapid HIV-1 recency test using 500 longitudinal plasma specimens from 107 seroconverters. The mean duration of recent infection (MDRI) was estimated via binomial regression with maximum likelihood modeling. The false recent rate (FRR) was assessed using samples from individuals with long-term infection, including those on antiretroviral therapy (ART). Concordance was compared with two commercial LAg-EIA kits (Maxim and KingHawk). The rapid assay yielded an MDRI of 123 days (95% CI: 87\u2013138), shorter than Maxim (152 days, 95% CI: 137\u2013172) and KingHawk (131 days, 95% CI: 107\u2013140). Among ART-na\u00efve individuals infected for over 1 year, FRR was 5.3%, similar to Maxim (5.9%) and slightly higher than KingHawk (2.7%). High concordance was observed with Maxim (93.1%, kappa = 0.743) and KingHawk (89.4%, kappa = 0.558). In ART-treated individuals, FRR was significantly higher in the early ART group (69.9%) compared to the late ART group (20.2%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001). The novel rapid HIV-1 recency assay demonstrates acceptable MDRI and FRR and strong agreement with commercial LAg-EIA kits. Its simplicity and rapid turnaround make it a promising tool for decentralized surveillance and targeted HIV interventions, especially in resource-limited settings.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>Rapid detection of recent HIV-1 infections is essential for monitoring ongoing transmission and guiding targeted prevention efforts. However, currently used laboratory-based recency assays require specialized facilities and trained personnel, limiting their use in decentralized or resource-limited settings. In this study, we evaluated a newly developed rapid test that identifies recent HIV-1 infections within minutes using a simple, instrument-free format. The test showed strong agreement with two widely used laboratory assays and demonstrated performance suitable for surveillance applications. Its ease of use, rapid turnaround, and minimal infrastructure requirements make this rapid test a practical tool for expanding real-time HIV monitoring and improving the efficiency of public health responses.<\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/jcm.01208-25","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T13:00:52Z","timestamp":1767013252000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Developing and evaluating a novel rapid test for recent HIV-1 infection: comparison with commercial LAg-EIA assays"],"prefix":"10.1128","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3203-5898","authenticated-orcid":false,"given":"Jing","family":"Liu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04wktzw65","id-type":"ROR","asserted-by":"publisher"}],"name":"National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Center for AIDS\/STD Control and Prevention, Chinese Center for Disease Control and Prevention","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04wktzw65","id-type":"ROR","asserted-by":"publisher"}],"name":"National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Center for AIDS\/STD Control and Prevention, Chinese Center for Disease Control and Prevention","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Runhua","family":"Ye","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00qzjvm58","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of AIDS Control and Prevention, Dehong Prefecture Center for Disease Control and Prevention","place":["Mangshi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shitang","family":"Yao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00qzjvm58","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of AIDS Control and Prevention, Dehong Prefecture Center for Disease Control and Prevention","place":["Mangshi, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyu","family":"Zhu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04wktzw65","id-type":"ROR","asserted-by":"publisher"}],"name":"National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Center for AIDS\/STD Control and Prevention, Chinese Center for Disease Control and Prevention","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Jiang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04wktzw65","id-type":"ROR","asserted-by":"publisher"}],"name":"National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Center for AIDS\/STD Control and Prevention, Chinese Center for Disease Control and Prevention","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2344-6561","authenticated-orcid":true,"given":"Cong","family":"Jin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04wktzw65","id-type":"ROR","asserted-by":"publisher"}],"name":"National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Center for AIDS\/STD Control and Prevention, Chinese Center for Disease Control and Prevention","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","unstructured":"Joint United Nations Programme on HIV\/AIDS (UNAIDS). 2025.
