A recent study showed that the different response patterns not only provide complementary information about etiology, but also the probability of HAC in these patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>We aimed to determine the diagnostic test performance of LDDT response patterns in a population of dogs from an animal hospital.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The electronic database was retrospectively searched for dogs suspected of HAC that were given an LDDT. Dogs with acute non\u2010adrenal illnesses during the test were excluded. Response patterns were classified as complete suppression, lack of suppression, partial suppression, escape, inverse, and increasing patterns.

The positive (+) LRs (95% CI) for the lack of suppression, partial suppression, escape, and an inverse pattern to diagnose HAC were infinite, 8.09 (2\u201032.72), 3.23 (0.75\u201014), and 0.2 (0.06\u20100.73), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The study confirms that the \u201clack of suppression\u201d pattern strongly supports a diagnosis of HAC. It shows that the \u201cpartial suppression\u201d pattern moderately increases, and the \u201cinverse\u201d pattern decreases the likelihood of HAC. The fact that the study found no association between the \u201cescape\u201d pattern and a diagnosis of HAC, does not support its integration into decision making.<\/jats:p><\/jats:sec>","DOI":"10.1111\/vcp.12958","type":"journal-article","created":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T04:20:21Z","timestamp":1615954821000},"page":"62-70","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Patterns
