Does Disseminated Nontuberculous Mycobacterial Disease cause False-positive Determine TB-LAM Lateral Flow Assay Results?

Background The Determine TB-LAM (LF-LAM) can detect lipoarabinomannan, a glycolipid found in mycobacteria, in the urine of HIV-infected patients with disseminated TB. Whether disseminated nontuberculous mycobacterial (NTM) infection causes false-positive results has not been adequately assessed.
