Physiology : The acid-fast stain test for bacteria is a laboratory test to detect the presence of TB or other pathogenic, acid fast bacteria in a sample of blood, or other body tissues.

The samples are then heat-fixed and treated with an acid-fast stain for TB mycobacteria. Access to reproducible and high-throughput staining with these methods is limited by a lack of trained staff to ...

Prof. Dr. Panan mentioned the various advantages and disadvantages of current testing methods for tuberculosis as follows: Microscopic examination using acid-fast staining is a simple method.

“Challenges still exist in NAA’s broader use, especially among patients with nonsputum specimens, patients with extrapulmonary TB, patients with acid-fast-bacilli-smear-negative TB, and ...
