ACID-FAST BACTERIUM, AUROMINE RHODAMINE HISTOCHEMICAL STAIN

Test Code APAFBAR 
Test ACID-FAST BACTERIUM, AUROMINE RHODAMINE HISTOCHEMICAL STAIN 
Description To identify Acid Fast Bacilli in paraffin embedded tissue using Fluorescent Stain procedure as well as Mycobacterium species in specimens and culture. This fluorescent method stains mycobacteria by binding dye to the mycolic acid of the cell wall. Once stained the cells resist decolorization with acidified organic solvents and therefore called acid-fast. Although the ability to retain the auramine-rhodamine after washing with alcohol or weak acids is a primary feature of this genus, it is not entirely unique to the genus. Other bacteria which contain mycolic acids, such as Nocardia, can also exhibit acid-fast staining features.

NOTE: This test is usually ordered in conjunction with a pathology consultation. The pathology professional component will be billed separately by the consulting pathologist.
