Recently, other technologies have been developed including fluorescence microscopy for smear tests (10% more sensitive than light microscopy), LED fluorescent microscopy for inexpensive imaging equipment that can be used in the field without the need for a darkroom, and rapid culturing techniques to reduce incubation time.[3] Despite all the improvements that have been made in TB diagnosis, no simple inexpensive POC test is currently available. The techniques mentioned above either focus on variations of microscopy or culture technique. In either case, these methods require lab facilities and highly trained personnel that typically are not available in many rural or low resource areas.
