Molecular platforms offer highly multiplexed assays for diverse viral and bacterial detection, alongside antimicrobial resistance markers, providing the potential to significantly shape patient care. Despite the superiority in sensitivity and speed, debates continue regarding the clinical role of multiplex molecular testing, notably in comparison to standard methods and distinguishing colonization from infection. Recent guidelines endorse molecular pneumonia panels for enhanced sensitivity and rapidity, but implementation requires addressing methodological differences and ensuring clinical relevance. Diagnostic stewardship should be leveraged to optimize pneumonia testing, emphasizing pre- and post-analytical strategies. Collaboration between clinical microbiologists and bedside providers is essential in developing implementation strategies to maximize the clinical utility of multiplex molecular diagnostics in pneumonia. This narrative review explores these multifaceted issues, examining the current evidence on the clinical performance of multiplex molecular assays in pneumonia, and reflects on lessons learned from previous microbiological advances. Additionally, given the complexity of pneumonia and the sensitivity of molecular diagnostics, diagnostic stewardship is discussed within the context of current literature, including implementation strategies that consider pre-analytical and post-analytical modifications to optimize the clinical utility of advanced technologies like multiplex PCR.<\/jats:p>","DOI":"10.3390\/diagnostics14070752","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T01:26:10Z","timestamp":1712021170000},"page":"752","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Breaking Boundaries in Pneumonia Diagnostics: Transitioning from Tradition to Molecular Frontiers with Multiplex PCR"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-0693-1658","authenticated-orcid":false,"given":"Alyssa M.","family":"Walker","sequence":"first","affiliation":[{"name":"bioMerieux, 69280 Marcy L\u2019etoile, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4542-6203","authenticated-orcid":false,"given":"Tristan T.","family":"Timbrook","sequence":"additional","affiliation":[{"name":"bioMerieux, 69280 Marcy L\u2019etoile, France"},{"name":"Department of Pharmacotherapy, College of Pharmacy, University of Utah, Salt Lake City, UT 84112, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0971-1696","authenticated-orcid":false,"given":"Benjamin","family":"Hommel","sequence":"additional","affiliation":[{"name":"bioMerieux, 69280 Marcy L\u2019etoile, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2949-5484","authenticated-orcid":false,"given":"Andrea M.","family":"Prinzi","sequence":"additional","affiliation":[{"name":"bioMerieux, 69280 Marcy L\u2019etoile, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"473","DOI":"10.1017\/ice.2018.11","article-title":"The Role of an Antimicrobial Stewardship Team in the Use of Rapid Diagnostic Testing in Acute Care: An Official Position Statement of the Society of Infectious Diseases Pharmacists","volume":"39","author":"Hill","year":"2018","journal-title":"Infect.
