Newest firstAim: This study was conducted to assess, for the first time, patterns in common drugs of abuse detected in urine samples from a large series of patients treated at a tertiary university hospital and the role of age and sex in these patterns. Methods: This study included samples from all patients analyzed at the Dr. Negrín University Hospital Laboratory from January 2021 to December 2025 with positive immunoassay t…
Open article record in new tab ↗Highlights What are the main findings? Agreement between immunoassay screening and LC–MS/MS confirmation varied markedly across analyte groups in urine samples with results near assay cutoff values.Immunoassays produced notable false-positive findings for amphetamines and opioids and false-negative findings for cannabinoids and opioids. What are the implications of the main findings? Immunoassay results close to c…
Open article record in new tab ↗The rapid detection of 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH), a primary cannabis metabolite, is critical for forensic and workplace drug testing. However, conventional immunoassays often lack sensitivity and objectivity. We developed a portable lateral flow immunoassay device with a microfluidic cartridge and fluorescent reader for the semi-quantitative detection of THC-COOH in urine. A test-to-…
In this study, a fluorometric and colorimetric dual-readout lateral flow immunoassay (LFIA) using antibody functionalized polydopamine-coated gold nanoparticles (Au@PDAs) as a probe was developed for the detection of carbendazim (CBD). Colloidal gold nanoparticles (AuNPs) were coated with polydopamines (PDA) by the oxidation of dopamine to synthesize Au@PDA nanoparticles. The Au@PDA nanoparticles mediated ZnCdSe/Z…
Open article record in new tab ↗Marijuana is listed as a Schedule I substance under the American Controlled Substances Act of 1970. As more U.S. states and countries beyond the U.S. seek legalization, demands grow for identifying individuals driving under the influence (DUI) of marijuana. Currently no roadside DUI test exists for determining marijuana impairment, thus the merit lies in detecting the primary and the most sought psychoactive compo…
