Test Details: Mycobacterium tuberculosis MTB belongs to the group called Acid-fast bacteria or acid-fast bacilli (AFB). These are a group of bacteria sharing the property of acid fastness. This unique property helps in classifying and detecting acid-fast bacteria like Mycobacteria. The fluorescent Smear test uses a fluorescent stain and iLED microscopy for detecting the fluorescence emitted by the bacteria. The test provides a count of bacilli, bacterial load in the sample is estimated and further tests can be determined.
