This acid-fast bacilli in brief AFB staining or Ziehl-Neelsen staining method is a modification of Ehrlich's (1882) method. Its name is from the surnames of German doctors, bacteriologist Franz Ziehl(1859-1926), and pathologist Friedrich Neelsen (1854-1898). Principle of AFB Stainin An AFB stain can help confirm that your recovery is complete and the tuberculosis is gone. What Do the Results Mean? If your AFB stain does not have any bacteria that hold onto the dye, then the. Acid-Fast Stain- Principle, Procedure, Interpretation and Examples. It is the differential staining techniques which was first developed by Ziehl and later on modified by Neelsen. So this method is also called Ziehl-Neelsen staining techniques. Neelsen in 1883 used Ziehl's carbol-fuchsin and heat then decolorized with an acid alcohol, and. Acid-fast bacillus (AFB) is a type of bacteria that causes tuberculosis (TB) and other infections. AFB tests look for AFB bacteria in sputum. An AFB smear test gives results in 1-2 days but can't confirm a diagnosis. An AFB culture can confirm a diagnosis, but results take 6-8 weeks. Learn more

AFB smear—a microscopic examination of a person's sputum or other specimen that is stained to detect acid-fast bacteria. It is a rapid test used to provide presumptive results within one to two days. It is valuable in helping to make decisions about treatment while waiting for culture results The preferred method of identification is an AFB stain, otherwise called an acid-fast bacteria stain. Mycolic acid is the mechanism responsible for the acid-fast property. The walls of the bacteria produce this waxy substance called mycolic acid. This acid links with substances within the cell walls of the bacteria, making them resistant to. Staining: Introduction, Types, Gram stain, AFB stain, Principle, Procedure, Result Interpretation.

Procedure of Acid Fast Stain. Prepare and fix the specimen smear prior to staining. Place a small strip of blotting or filter paper over the top of the specimen, and place the slide over a boiling hot water bath on a mesh surface. Cover the filter paper with the primary stain, carbolfuchsin. Leave the slide on the water bath for 3 to 5 minutes AFB (acid fast bacilli) stain. This stain uses carbol-fuchsin to stain the lipid walls of acid fast organisms such as M. tuberculosis. The most commonly used method is the Ziehl-Neelsen method, though there is also a Kinyoun's method Ziehl-Neelsen (classic): common method; bacteria stain bright red due to retention of carbol-fuchsin dye; background is methylene blue counterstain; procedure involves heat (#1, #2) Ziehl-Neelsen (modified bleach): may be more sensitive than classic stain (Acta Cytol 2008;52:325,J Cytol 2012;29:165) Ziehl-Neelsen (modified for stool specimens): does not require heating (Centers for Disease.

The specificity of ZN microscopy is high but sensitivity is imperfect [15]. Conventional fluorescent microscopy has higher sensitivity than ZN and takes less time, but uptake.

Expectorated sputum is stained for AFB through a variety of methods; Ziehl-Neelson, Kinyoun, and fluorochrome stains can be used. Processing the sputum for AFB staining can be done with relative ease and with a good laboratory can be reliably interpreted. However, the sensitivity of sputum smear for the diagnosis of pulmonary tuberculosis. AFB smear microscopy refers to the quick and inexpensive microscopic examination of clinical specimens using a fluorochrome stain. One must take note that smear microscopy is unable to differentiate among different species of Mycobacteria, and it is also unable to detect the viability of bacilli Catalogue Number. 116450. Description. TB-COLOR STAINING KIT FOR THE MICROSCOPI. Overview. Mycobacteria are difficult to stain because of the high proportion of lipid and wax in their cell walls. Tb-color offers a modified Ziehl-Neelsen staining, which works without heating (also known as the Kinyoun method). Pre-treatment with Sputofluol frees. An acid-fast bacillus (AFB) smear is used to look for AFB in a sample from the site of suspected infection. For the smear, the sample is spread thinly onto a glass slide, treated with a special stain, and examined under a microscope The Acid-Fast Bacilli Test or AFB Test thus tests the existence of bacterial infection in the body by collecting samples from blood, urine, stool, phlegm, etc. and is used to identify various bacteria-caused diseases.

Here there is a rising problem , in ZN staining (AFB) . With consideration of factors that are not inevitable by nature like climate change . The variation of climatic change is the one of the most cause of many bias over in ZN staining of AFB. This is leading to many deaths world wide i therefore request a good set up of the stain at both. • AFB difficult to stain due to the high lipid content of cell wall (mycolic acids) • Unique capability of binding fuchsin stain which cannot be de-colorized by acid-alcohol • AFB staining detects both viable and non-viable organisms • Recommended to be tested, read and reported within 24 hr An AFB Stain alone without culture is appropriate only when following respiratory specimens on previously diagnosed patients. Studies have shown that AFB stain without culture has a poor negative predictive value. For a higher predictive value, order AFB culture (Acid-Fast Bacillus (AFB) Culture, ARUP test code 0060152), which adds an AFB stain
