Understanding the AFB/ZN Stain Test

The AFB/ZN Stain (Acid-Fast Bacilli/Ziehl-Neelsen Stain) test is used to identify acid-fast bacilli such as Mycobacterium tuberculosis (MTB) in clinical specimens. This method, developed by Ziehl and Neelsen, involves the staining of bacterial cells with a red dye and then counterstaining with a blue dye. Acid-fast bacilli retain the red stain even after an acid-alcohol solution is applied, which helps differentiate them from non-acid-fast cells.

Why is this test important?

Tuberculosis is a serious, potentially deadly infectious disease that primarily affects the lungs but can impact other parts of the body as well. Accurate and prompt diagnosis is vital to commence appropriate treatment and prevent the spread of the disease.
