Multidrug-resistant TB (MDR-TB) poses additional challenges, requiring advanced diagnostic and treatment strategies. This study evaluates the BD MAX MDR-TB molecular test for a rapid diagnosis of MDR-TB, detecting resistance to rifampicin (RIF) and isoniazid (INH). The BD MAX MDR-TB test, utilizing real-time PCR, was used to analyze specimens collected from TB-suspected patients, identifying MTB DNA and mutations associated with rifampicin and isoniazid resistance. Results were compared with traditional drug susceptibility testing, and 79 out of 638 samples tested were positive for MTB DNA, with 65 showing a sufficient amount of genetic material for resistance gene identification. The BD MAX test showed a 100% correlation with phenotypic rifampicin resistance, though discrepancies were noted for isoniazid resistance, with a 93% concordance. The BD MAX MDR-TB test is an effective tool for a rapid diagnosis of MDR-TB, especially for rifampicin resistance. However, it may not detect certain mutations related to isoniazid resistance. Complementary tests like Xpert MTB\/XDR or whole-genome sequencing could improve diagnostic accuracy and support more effective TB control strategies.<\/jats:p>","DOI":"10.3390\/pathogens14060602","type":"journal-article","created":{"date-parts":[[2025,6,19]],"date-time":"2025-06-19T06:11:07Z","timestamp":1750313467000},"page":"602","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Usefulness of the BD MAX MDR-TB Molecular Test in the Rapid Diagnosis of Multidrug-Resistant Tuberculosis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6787-1378","authenticated-orcid":false,"given":"Tomasz","family":"Bogiel","sequence":"first","affiliation":[{"name":"Department of Propaedeutics of Medicine and Infection Prevention Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toru\u0144, 9 Maria Sk\u0142odowska-Curie Street, 85-094 Bydgoszcz, Poland"},{"name":"Clinical Microbiology Laboratory, Dr. Antoni Jurasz University Hospital No. 1 in Bydgoszcz, 9 Maria Sk\u0142odowska-Curie Street, 85-094 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edyta","family":"Dolska","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u0142gorzata","family":"Zimna","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kornelia","family":"Nakonowska","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorota","family":"Krawiecka","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata","family":"\u017bebracka","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Pochowski","sequence":"additional","affiliation":[{"name":"Department of Microbiological Diagnostics, Kujawsko-Pomorskie Pulmonology Centre in Bydgoszcz, 85-326 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9719-9663","authenticated-orcid":false,"given":"Agnieszka","family":"Krawczyk","sequence":"additional","affiliation":[{"name":"Department of Molecular Medical Microbiology, Chair of Microbiology, Jagiellonian University Medical College, 31-121 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,19]]},"reference":[{"key":"ref_1","unstructured":"Tobin, E.H., and Tristram, D.
