We screened all patients undergoing diagnostic testing for secondary hypertension from January 2017 to May 2022 at authors\u2019 center. For inclusion, patients must be on DHP\u2010CCBs monotherapy for hypertension. Aldosterone and renin concentration were measured pre\u2010 and post\u2010washout. Confirmatory tests were conducted in patients with positive screen [combination of ARR &gt;2.5 (ng\/dL)\/(\u03bcIU\/mL), aldosterone \u226510\u00a0ng\/dL, and renin \u22648.2 \u03bcIU\/mL] after washout. The final analysis included a total of 198 patients (median age: 49.5 years and 117 men). Confirmatory tests identified PA in 31 (15.7%) patients. Aldosterone\u2010to\u2010renin ratio (ARR) increased in 158 (79.8%) patients after washout. In 168 patients with a negative pre\u2010washout screen, 22 turned positive after washout, and 14 were diagnosed PA. Consequently, the missed diagnosis rate of PA was 45.2% (14\/31) when using standard positive screen criteria before washout of DHP\u2010CCBs monotherapy. Exploratory analysis indicated that a pre\u2010washout ARR cutoff of &gt;1.2 (ng\/dL)\/(\u03bcIU\/mL) demonstrated 0.97 sensitivity and 0.75 specificity. In conclusions, caution is warranted when interpretating screening results from patients on DHP\u2010CCBs monotherapy due to the potential risk of missed diagnosis. Preliminary data suggest that ARR \u22641.2 (ng\/dL)\/(\u03bcIU\/mL) before washout may serve as a candidate threshold for excluding PA in these patients, though this observation remains a\u00a0hypothesis\u2010generating finding that requires further investigation.<\/jats:p>","DOI":"10.1111\/jch.70338","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T09:45:17Z","timestamp":1786441517000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Performance
