It was previously also used as an avicide. Detection of AC in blood samples or in body tissues collected postmortem is key for the diagnosis of clinical cases and a requirement for surveillance of secondary toxicosis, including potential cases in wild animals. Reports on poisoning of humans and non-laboratory animals confirmed by the detection of AC or its metabolites are available, however poisoning of domestic animals are rarely available. Furthermore, reports on clinical cases in domestic animals rarely report quantifications of AC in blood or body tissues. The present study describes the validation of a quantitative ultra high performance liquid chromatography--tandem mass spectrometry (UHPLC--MS-MS) method that can be used in cases of suspected AC poisoning in cats. The validation study showed the method to be fit for purpose. In serum, the limit of quantification was 100\u2009ng\/mL and the limit of detection was 30\u2009ng\/mL. The new analytical method was applied on blood samples collected from 20 individual cats with a preliminary clinical diagnosis of acute AC poisoning. AC was confirmed in all 20 feline blood samples, and the concentration range of AC was 538\u201317,500\u2009ng\/mL. The quantitative method developed in this study was found to be a fast and selective method for confirmation of AC poisoning using blood samples from cats.<\/jats:p>","DOI":"10.1093\/jat\/bkab087","type":"journal-article","created":{"date-parts":[[2021,7,27]],"date-time":"2021-07-27T16:31:07Z","timestamp":1627403467000},"page":"651-657","source":"Crossref","is-referenced-by-count":5,"title":["Development and Validation of a Quantitative UHPLC\u2013MS-MS Method for the Determination of Alpha-Chloralose in Feline Blood and Application on Blood Samples Collected from Cats with Symptoms of Alpha-Chloralose Poisoning"],"prefix":"10.1093","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9311-6982","authenticated-orcid":false,"given":"Ulrika","family":"Windahl","sequence":"first","affiliation":[{"name":"Swedish National Veterinary Institute (SVA) , Uppsala 75189, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Lundgren","sequence":"additional","affiliation":[{"name":"University Animal Hospital, Swedish University of Agricultural Sciences , Uppsala 75007, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margareta","family":"Sprycha","sequence":"additional","affiliation":[{"name":"Swedish National Veterinary Institute (SVA) , Uppsala 75189, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Tegner","sequence":"additional","affiliation":[{"name":"University Animal Hospital, Swedish University of Agricultural Sciences , Uppsala 75007, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristoffer","family":"Dreimanis","sequence":"additional","affiliation":[{"name":"University Animal Hospital, Swedish University of Agricultural Sciences , Uppsala 75007, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annica","family":"Tevell \u00c5berg","sequence":"additional","affiliation":[{"name":"Swedish National Veterinary Institute (SVA) , Uppsala 75189, Sweden"},{"name":"Department of Medicinal Chemistry, Analytical Pharmaceutical Chemistry, Uppsala University , Uppsala 75123, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,7,27]]},"reference":[{"key":"2022071417283281400_R1","first-page":"1","article-title":"The pharmacology of chloralose.
