False-positive QuantiFERON TB-Gold test due to Mycobacterium gordonae DIAGNOSTIC MICROBIOLOGY AND INFECTIOUS DISEASE Gajurel, K., Subramanian, A. K. 2016; 84 (4): 315-317


We report a case of QuantiFERON TB-Gold conversion associated to Mycobacterium gordonae in an elderly male from an assisted living facility without known risk factors for tuberculosis. This knowledge of environmental mycobacteria causing positive quantiferon assays is important to avoid unnecessary treatment of false-positive latent tuberculosis, especially in the absence of well-established positive predictive value of quantiferon conversion.
