Question

Quizplus · Accepted Answer

Acid-fast bacilli (AFB) smear is used for the diagnosis of tuberculosis (TB). AFB are stained with a special dye and identified under a microscope, which helps in confirming the presence of Mycobacterium tuberculosis, the bacteria that causes TB. AFB smear is not useful for the diagnosis of other respiratory infections, pulmonary embolism or pleural effusion.
