Additionally, among 33,937 cases with an acid-fast-bacilli-smear-positive result, 70.9% had an NAA test performed, whereas 38% of the 30,244 with an acid-fast-bacilli-smear-negative result had an ...

Airborne precautions for tuberculosis, including a negative-pressure room, were instituted initially but were subsequently discontinued when the smear for acid-fast bacilli returned a negative result.

Repeated sputum examinations had been negative for acid-fast bacilli by smear and culture, and bronchoscopy revealed an inflammatory stenosis of the right-middle-lobe orifice.

"Our results indicate that ELISpot is an important advancement to rapidly distinguish acid-fast bacilli sputum smear-negative active TB from LTBI in routine clinical practice." ...

At present, the traditional rapid laboratory diagnosis of TB is based on the WHO-recommended acid fast bacilli smear, although this method also shows some specific limitations.

"Our results indicate that ELISpot is an important advancement to rapidly distinguish acid-fast bacilli sputum smear-negative active TB from LTBI in routine clinical practice." ...

Clinicians also ordered a tuberculin skin test, an interferon-γ release assay, nucleic acid amplification testing for tuberculosis, an acid-fast bacilli smear microscopy, and HIV antibody testing ...

Trained study nurses collected a sputum sample for acid-fast bacilli smear microscopy (AFB) and mycobacterial culture, and performed urine LAM testing using Determine™ TB LAM in the clinic.

Smear microscopy for TB is sometimes called AFB testing, because mycobacteria are ‘acid-fast bacilli’ (AFB). This means that certain dyes adhere to the waxy coat of mycobacteria and remain visible ...

"This review underscores the particular importance of prompt and thorough investigations for tuberculosis cases confirmed by positive smear for acid-fast bacilli in which patients have experienced ...
