The analysis of paired blood and oral fluid samples from the same subject led to the identification of a false negative ELISA screen for benzoylecgonine (BE) in blood. Investigation demonstrated that the issue was only with the Neogen\u00ae BE assay, and sample dilution did not remedy the problem. Based on subsequent monitoring of ELISA screens in blood, the false negative anomaly has only been identified in one specimen, and the cause remains undetermined.<\/jats:p>","DOI":"10.1111\/1556-4029.70015","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T05:47:47Z","timestamp":1741758467000},"page":"1217-1221","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["False negative <scp>ELISA<\/scp> screen for benzoylecgonine in blood using the Neogen\u00ae assay"],"prefix":"10.1111","volume":"70","author":[{"given":"Jennifer F.","family":"Limoges","sequence":"first","affiliation":[{"name":"Toxicology New York State Police Forensic Investigation Center  Albany New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seth J.","family":"Tracy","sequence":"additional","affiliation":[{"name":"Toxicology New York State Police Forensic Investigation Center  Albany New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heidi E.","family":"Grieger","sequence":"additional","affiliation":[{"name":"Toxicology New York State Police Forensic Investigation Center  Albany New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,3,11]]},"reference":[{"key":"e_1_2_10_2_1","first-page":"409","volume-title":"Clarke's analytical forensic toxicology","author":"Hand C","year":"2013"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1258\/acb.2011.011073"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.5858\/2006\u2010130\u20101600c\u2010FUIALO"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.4155\/bio.09.81"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1567-7192(04)80005-6"},{"issue":"2","key":"e_1_2_10_7_1","first-page":"105","article-title":"Interferences in immunoassay","volume":"25","author":"Tate J","year":"2004","journal-title":"Clin Biochem Rev"},{"key":"e_1_2_10_8_1","unstructured":"Drug Enforcement Administration.Controlled substances \u2013 alphabetical order.
