It accentuates the imperative of bolstering diagnostic, preventive, and treatment modalities for tuberculosis (TB) to fulfill the ambitious targets set forth by the World Health Organization aimed at reducing TB-related mortalities and the incidence of new TB cases. The document underscores the significance of addressing LTBI as a means of averting the progression to active TB, particularly in regions burdened with high TB prevalence, such as India. An in-depth analysis of the spectrum delineating latent and active TB disease is provided, elucidating the risk factors predisposing individuals with LTBI to progress towards active TB, including compromised immune functionality, concurrent HIV infection, and other immunosuppressive states. Furthermore, the challenges associated with LTBI diagnosis are elucidated, encompassing the absence of a definitive diagnostic assay, and the merits and demerits of tuberculin skin testing (TST) and interferon-\u03b3 release assays (IGRAs) are expounded upon. The document underscores the necessity of confronting these challenges and furnishes a meticulous examination of the advantages and limitations of TST and IGRAs, along with the intricacies involved in interpreting their outcomes across diverse demographics and settings. Additionally, attention is drawn towards the heritability of the interferon-\u03b3 response to mycobacterial antigens and the potential utility of antibodies in LTBI diagnosis.<\/jats:p>","DOI":"10.4081\/monaldi.2024.2984","type":"journal-article","created":{"date-parts":[[2024,5,3]],"date-time":"2024-05-03T03:50:26Z","timestamp":1714708226000},"source":"Crossref","is-referenced-by-count":6,"title":["Latent tuberculosis diagnostics: current scenario and review"],"prefix":"10.4081","volume":"95","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4538-6926","authenticated-orcid":false,"given":"Amitesh","family":"Gupta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7718-0778","authenticated-orcid":false,"given":"Eshutosh","family":"Chandra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0996-8587","authenticated-orcid":false,"given":"Shipra","family":"Anand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4581-609X","authenticated-orcid":false,"given":"Naresh","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3853-2152","authenticated-orcid":false,"given":"Richa","family":"Arora","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2914-4683","authenticated-orcid":false,"given":"Divyanshi","family":"Rana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7723-4866","authenticated-orcid":false,"given":"Parul","family":"Mrigpuri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2549","published-online":{"date-parts":[[2024,5,3]]},"reference":[{"key":"39616","unstructured":"World Health Organization.
