This study explored the diagnostic potential of salivary cytokines, uric acid, and testosterone in distinguishing PCOS patients from healthy controls, as well as to examine their associations with hormonal and metabolic profiles within the PCOS group. Methods: Forty-one adolescent girls with PCOS and thirty healthy controls participated in the study. The PCOS group included both normal-weight and overweight individuals, allowing evaluation of salivary biomarkers across different nutritional statuses. Salivary levels of TNF-\u03b1, IL-6, IL-1\u03b2, testosterone, and uric acid were measured and compared between the groups. A receiver operating characteristic (ROC) analysis was performed to assess the diagnostic value of each biomarker. Results: Salivary TNF-\u03b1, IL-6, and IL-1\u03b2 showed high diagnostic accuracy (AUC = 0.921, 0.891, and 0.870, respectively), supporting their potential as non-invasive biomarkers. The diagnostic accuracy of salivary cytokines and testosterone remained high even in normal-weight participants, suggesting that low-grade inflammation and hormonal disturbances in PCOS are not limited to excess body weight. Salivary testosterone was strongly associated with hyperandrogenism, while uric acid correlated with the cortisol\/DHEA-S ratio, indicating possible links to metabolic stress. Conclusions: In conclusion, salivary assays may offer a valuable, non-invasive tool for the early diagnosis of PCOS in adolescents, including normal-weight girls. This approach could facilitate the timely detection of inflammatory and hormonal imbalances, supporting earlier interventions and more personalized care.<\/jats:p>","DOI":"10.3390\/jcm14176159","type":"journal-article","created":{"date-parts":[[2025,9,2]],"date-time":"2025-09-02T13:01:13Z","timestamp":1756818073000},"page":"6159","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Pilot Study of the Role of Salivary Biomarkers in the Diagnosis of PCOS in Adolescents Across Different Body Weight Categories"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5091-3316","authenticated-orcid":false,"given":"Justyna","family":"Opydo-Szymaczek","sequence":"first","affiliation":[{"name":"Chair and Department of Pediatric Dentistry, Poznan University of Medical Sciences, 70 Bukowska Street, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3224-4937","authenticated-orcid":false,"given":"Natalia","family":"Wendland","sequence":"additional","affiliation":[{"name":"Chair and Department of Pediatric Dentistry, Poznan University of Medical Sciences, 70 Bukowska Street, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6691-3863","authenticated-orcid":false,"given":"Dorota","family":"Formanowicz","sequence":"additional","affiliation":[{"name":"Chair and Department of Medical Chemistry and Laboratory Medicine, Poznan University of Medical Sciences, 8 Rokietnicka Street, 60-806 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4526-5112","authenticated-orcid":false,"given":"Anna","family":"Blacha","sequence":"additional","affiliation":[{"name":"Chair and Department of Medical Chemistry and Laboratory Medicine, Poznan University of Medical Sciences, 8 Rokietnicka Street, 60-806 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1385-5641","authenticated-orcid":false,"given":"Gra\u017cyna","family":"Jarz\u0105bek-Bielecka","sequence":"additional","affiliation":[{"name":"Chair and Department of Gynaecology, Poznan University of Medical Sciences, 22 Polna Street, 60-535 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0379-2520","authenticated-orcid":false,"given":"Paulina","family":"Radomyska","sequence":"additional","affiliation":[{"name":"Chair and Department of Pediatric Dentistry, Poznan University of Medical Sciences, 70 Bukowska Street, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5481-7477","authenticated-orcid":false,"given":"Dominika","family":"Kruszy\u0144ska","sequence":"additional","affiliation":[{"name":"Chair and Department of Pediatric Dentistry, Poznan University of Medical Sciences, 70 Bukowska Street, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9533-2950","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Mizgier","sequence":"additional","affiliation":[{"name":"Department of Sports Dietetics, Chair of Dietetics, Faculty of Health Sciences, Poznan University of Physical Education, Kr\u00f3lowej Jadwigi 27\/39, 61-871 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,31]]},"reference":[{"key":"ref_1","first-page":"17455057221117966","article-title":"An update on polycystic ovary syndrome: A review of the current state of knowledge in diagnosis, genetic etiology, and emerging treatment options","volume":"18","author":"Islam","year":"2022","journal-title":"Women\u2019s Health"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Meczekalski, B., Niwczyk, O., Kostrzak, A., Maciejewska-Jeske, M., Bala, G., and Szeliga, A.
