Tuberculosis (TB) is one of the top ten causes of death worldwide. TB can remain latent for years, and early stages of active disease can remain mild for months making diagnosis challenging. Additionally, TB is most common in third world countries that lack the healthcare systems to support costly specialized testing equipment. The only tests available in these countries require days to confirm a positive TB diagnosis, and many patients never receive a diagnosis because the health center is too far away to make a return trip. Therefore, there is a desperate need to develop rapid, cheap diagnostics to identify patients with TB.
