• We recommend that acid-fast bacilli (AFB) smear micros-copy be performed, rather than no AFB smear microscopy, in all patients suspected of having pulmonary TB (strong recommendation, moderate-quality evidence). Remarks: False-negative results are sufficiently common that a negative AFB smear result does not exclude pulmonary TB.

AFB Microscopy •Examination of smears is a rapid, convenient and inexpensive test •All types of specimens can be evaluated –sputum, tissue, body fluids, etc. •Positive AFB smear results provide a first indication of mycobacterial infection and potential TB disease •Must be accompanied by additional testing
microscopy of two consecutive sputum specimens will identify the vast majority (95–98%) of smear-positive TB patients**. Moreover, microscopy can be decentralised to peripheral laboratories. Despite its advantages sputum smear microscopy does fall short in test sensitivity, especially for certain patient groups such as those living

The presence of acid-fast-bacilli (AFB) on a . sputum smear. or other specimen often indicates TB disease. Acid-fast microscopy is easy and quick, but it does not confirm a diagnosis of TB because some acid-fast-bacilli are not . M. tuberculosis. Therefore, a . culture. is done on all initial samples to confirm the diagnosis. (However, a ...

50-60% of AFB culture-positive clinical specimens may fail to reveal AFB on smear made from the specimen. As a consequence, culture techniques play a key role in the diagnosis of mycobacterial disease. Egg-based media, such as Lowenstein-Jensen (LJ) or Ogawa have been used for cultivation of mycobacteria for several decades.
