FAQ

What is the principle behind the acid-fast staining method?

The principle behind the staining of a smear sample is as follows:

  • Carbol fuchsin solubilizes lipoidal material in the Mycobacterial cell wall and penetrates into the cytoplasm with heat, making the cell appear red. 
  • Decolorizing agent is then applied, which removes non-acid fast cells due to their lack of lipoidal material in their cell wall, leaving them colorless. 
  • Acid-fast cells remain red due to the presence of large amounts of lipoidal material in their cell wall that resists the decolorizing solution. 
  • Counterstain, methylene blue, is applied, making decolorized cells absorb its color and appear blue while acid-fast cells retain the red color.

When is the best time for sample collection?

The morning hours are an ideal time to collect sputum samples for testing, as the concentration of bacteria is highest at this point. Doing so can help ensure maximum accuracy in the results obtained.

Acid Fast Stain (ZN Stain, AFB Stain) Test in Modasa

x

Sterling Accuris Diagnostics offers the Acid Fast Stain (ZN Stain, AFB Stain) Test in Modasa. This test is also called the Ziehl-Neelsen stain (ZN stain), the hot method of AFB staining, used to identify acid-fast organisms, mainly Mycobacteria.

Overview of Acid Fast Stain (ZN Stain, AFB Stain) Test

Acid-fast staining is a differential staining technique that differentiates acid-fast and non-acid-fast bacteria. Mycobacterium species contain large amounts of mycolic acid in their cell wall. Due to high lipid content, most dyes cannot enter easily through the cell wall, so Mycobacterium species cannot be stained by regular Gram staining. A special staining method is developed to stain such organisms called the Acid-fast staining method. It is also known as the Ziehl-Neelsen method.

For an accurate diagnosis, you can head to Sterling Accuris Diagnostics for an Acid Fast Stain (ZN Stain, AFB Stain) test in Modasa.
