Although the polymerase chain reaction is effective for the diagnosis of extrapulmonary tuberculosis (EPTB), it is typically unavailable in resource-limited situations. In contrast, the loop-mediated isothermal amplification (LAMP) assay is a relatively cost-effective and accessible method. Additionally, when combined with the procedure for ultra-rapid extraction (PURE) kit, which enables simple DNA extraction, LAMP can detect Mycobacterium tuberculosis in sputum within 1.5 hours using a simple procedure. In this study, we investigated the utility of the PURE-LAMP technique to diagnose three cases of EPTB and showed that it may potentially be a valuable tool for the diagnosis of EPTB.
