The measurement of nasal nitric oxide (nNO) against resistance has been suggested as a sensitive screening method. However, current recommendations argue for the use of expensive, chemiluminescence devices to measure nNO. This study aimed to compare nNO measurement using three different devices in distinguishing PCD patients from healthy controls and cystic fibrosis (CF) patients and to evaluate their diagnostic precision. The study included 16 controls, 16 PCD patients, and 12 CF patients matched for age and sex. nNO measurements were performed using a chemiluminescence device (Eco Medics CLD 88sp), and two devices based on electrochemical sensors (Medisoft FeNO+ and NIOX Vero) following standardized guidelines. Correlation estimation, Bland\u2013Altman, ROC curve, and one-way ANOVA were used to assess device differences and diagnostic performance. Significantly lower nNO output values were observed in PCD and CF patients compared to controls during exhalation against resistance. The correlation analysis showed high agreement among the three devices. ROC curve analysis demonstrated 100% sensitivity and specificity at different cut-off values for all devices in distinguishing PCD patients from controls (optimal cut-offs: EcoMedics 73, Medisoft 92 and NIOX 87 (nl min<jats:sup>\u22121<\/jats:sup> )). Higher nNO output values were obtained with the Medisoft and NIOX devices as compared to the EcoMedics device, with a bias of\u221219 nl min<jats:sup>\u22121<\/jats:sup> (95% CI: \u221273\u201335) and \u221221 nl min<jats:sup>\u22121<\/jats:sup> (\u221273\u201331) accordingly. These findings indicate that all three tested devices can potentially serve as diagnostic tools for PCD if device specific cut-off values are used. This last-mentioned aspect warrants further studies and consideration in defining optimal cut-offs for individual device.<\/jats:p>","DOI":"10.1088\/1752-7163\/ad10f9","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T12:11:32Z","timestamp":1702469492000},"page":"011001","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Device comparison study to measure nasal nitric oxide in relation to primary ciliary dyskinesia"],"prefix":"10.1088","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9600-1950","authenticated-orcid":true,"given":"Nils Oskar","family":"J\u00f5gi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3185-3316","authenticated-orcid":true,"given":"Karin","family":"Ersson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0784-0443","authenticated-orcid":true,"given":"Kjell","family":"Alving","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9591-8532","authenticated-orcid":true,"given":"Christina","family":"Krantz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrei","family":"Malinovschi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2023,12,13]]},"reference":[{"key":"jbrad10f9bib1","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.01090-2016","article-title":"European Respiratory Society guidelines for the diagnosis of primary ciliary Dyskinesia","volume":"49","author":"Lucas","year":"2017","journal-title":"Eur.
