Clinical Sites: 

Our study will examine whether hair levels of two key first line tuberculosis drugs will be useful markers to
identify individuals at highest risk of treatment failure in active tuberculosis. Our study aims to provide a lowcost
clinical tool using hair that can be noninvasively collected to monitor drug adherence among HIV-infected
and uninfected patients with active tuberculosis.
