Does Disseminated Nontuberculous Mycobacterial Disease Cause False-Positive Determine TB-LAM Lateral Flow Assay Results? A Retrospective Review

摘要

We retrospectively reviewed the Determine TB-LAM lateral flow assay (LF-LAM) results among human immunodeficiency virus–infected patients with disseminated nontuberculous mycobacterial (NTM) disease. LF-LAM was positive in 19 of 21 patients without evidence of tuberculosis (TB) coinfection. Although TB-NTM coinfection may have been underdiagnosed, our results suggest that disseminated NTM disease may cause false-positive LF-LAM results.
