Вы правы только в отношении микроскопии мазка - подчеркнуто, в странах где есть интернет и айфоны/смартфоны, используют иные технологии, надеюсь РФ медицински-технологически таки ближе к ним, чем к папуа-новой гвинее или другим странам застрявшим по развитию в прошлом столетии
Smear microscopy cannot differentiate between MTB and NTM. The introduction of nucleic acid amplification (NAA) tests for the detection of MTB directly from clinical specimens has greatly improved TB diagnostics. Currently, many commercial assays use different molecular approaches to amplify and detect MTB. Such tests can confirm the diagnosis of TB more reliably and with higher sensitivity than smear microscopy. Moreover, their high positive predictive values allow discrimination between MTB and NTM in smear positive specimens. If the AFB smear result is positive and the NAA result is negative, the patient can be presumed to have NTM lung disease. Therefore, NAA tests could be used as an additional test for patients with AFB smear-positive sputum for the rapid detection of MTB and differentiation from NTM.
Ultimately, the diagnosis of NTM lung disease is based on isolation of the organism from respiratory specimens, using solid and liquid media. The introduction of liquid culture methods has allowed for sensitive detection of both MTB and NTM38. The increased recovery rate is more prominent for NTM than MTB, especially in AFB smear-negative respiratory specimens, when liquid culture methods are combined with solid medium for mycobacterial culture.
