Usefulness of Light Emitting Diode (LED) fluorescent microscopy as a tool for rapid and effective method for the diagnosis of pulmonary tuberculosis

Background: Tuberculosis remains world`s leading cause of death from a single infectious agent. Fluorescence microscopy offers well-described benefits, comparing with brightfield microscopy, for the evaluation sputum smear samples for tuberculosis. We evaluated the diagnostic performance of fluorescence microscopy, using novel Light Emitting Diode (LED) technology as an alternative to the conventional fluorescence microscopy by Auramine stain as well as brightfield microscopy by Ziehl Neelsen (ZN) stain.
