Bright field microscopy uses carbol fuschin method which involves Ziehl-Neelsen technique and Fluorescence Microscopy comprises fluorochrome procedure using Auramine O or auramine-rhodamine stain.
It can be also be performed using Ziehl-Neelsen (ZN) staining or fluorescence microscopy (FM) using a fluorescent substance such as auramine phenol to increase the visualization (Ogbaini-Emovon, 2009)
Then, all the smears were stained with auramine O and examined with fluorescence microscopy for acid fast bacteria (AFB).
It shows that using IS6110 as a target gene in molecular pathology technique to diagnose TB patients has higher positive rate (51.5%), when compared with acid fast stain (31%) and auramine O fluorescent dyes (40.5%) with P < 0.05, and could distinguish non-TB Mycobacterium from MTB.[sup][5] In China, molecular biology technique confines to sputum samples, and traditionally, pathology diagnosis confines to histomorphology and pathogen investigation, both of which may have low sensitivity and specificity.[sup][4] Molecular pathology may be a better choice, especially for rare disease diagnosis, where diagnosis often depends on pathology.
Sputum samples were screened by fluorescent microscopy using Auramine O stain and smears found to be positive were confirmed by light microscopy using Ziehl-Neelsen's stain as per the standard protocols of both staining methods.
The auramine rhodamine dye is then used to stain the cells and visualized using a fluorescence microscope [39].
Samples collected in 2016 (n = 282) were stained using auramine O staining and read with a fluorescent light-emitting diode (LED) microscope (40x).

Soon after sputum sample collection, smear microscopy was done by using florescence microscopy (FM) and Auramine O staining procedure which is described as follows: first a sputum smear was prepared and allowed to air-dry; then this smear was heat-fixed.
Microscopy of gastric washings for acid-fast bacilli using the auramine stain was negative.
