Conventional methods for TB detection and diagnosis are traditionally performed in laboratories or hospitals. For example, the most common method for diagnosis of TB is the acid fast staining of a sputum sample which is then followed by a sputum smear microscopy test. However a disadvantage with the sputum smear test is its poor sensitivity, which is estimated to be at 70%.[1] Additionally, the sensitivity of sputum smear spectroscopy in field settings has been shown to be much lower (35%), especially in populations that have high rates of TB and HIV coinfection.[2] Culturing of mycobacterium from sputum samples is a more sensitive technique. Sputum samples are collected and cultured in either solid media or liquid media looking for the presence of the mycobacterium. However this methodology takes time to conduct (3-4 weeks for solid cultures, and 10-14 days for liquid cultures), which makes it difficult to employ in low resource settings that are typically far from testing facilities.
