In this study, we performed analysis for volatile organic compounds (VOCs) and proteins from the same EBC sample. Pooled EBC samples were split into two groups: three samples that utilized immersion thin film-solid phase microextraction (TF-SPME) sampling for VOC analysis and three samples that did not undergo TF-SPME sampling (non-TF-SPME). All six EBC samples were analyzed using liquid chromatography with tandem mass spectrometry (LC-MS\/MS) for proteomics analysis. VOCs were analyzed via two-dimensional gas chromatography-mass spectrometry (GC x GC-MS). One hundred and eighty-four VOCs were found to be more abundant in EBC samples compared to blank or controls. There was no significant difference in the number of proteins detected in the TF-SPME samples compared to the non-TF-SPME samples and 144 of the 206 total unique proteins detected were found in both sample groups. These results indicate that TF-SPME sampling does not negatively affect the number of proteins that can be detected in EBC. This work is a step towards linking VOC and protein data together to obtain multi-omics breath data from a single breath sample. EBC samples were collected as part of a vaccination clinical trial (NCT05346302).<\/jats:p>","DOI":"10.1088\/1752-7163\/adf34d","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T22:48:57Z","timestamp":1753310937000},"page":"041001","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Volatile organic compound and proteomics data from the same exhaled breath condensate sample"],"prefix":"10.1088","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6750-5757","authenticated-orcid":true,"given":"Shannon E","family":"Schrader","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua R","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"O\u2019Bryon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2582-8779","authenticated-orcid":true,"given":"Laura E","family":"Ruebush","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5845-6447","authenticated-orcid":true,"given":"Nicolaas E","family":"Deutz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jon H","family":"Wahl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brooke L","family":"Deatherage Kaiser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2025,8,4]]},"reference":[{"key":"jbradf34dbib1","doi-asserted-by":"publisher","DOI":"10.1088\/1752-7155\/2\/3\/037004","article-title":"Biomarkers in exhaled breath condensate: a review of collection, processing, and analysis","volume":"2","author":"Grob","year":"2008","journal-title":"J.
