From March 1998 to August 2009, 1538 non-respiratory samples collected from 1182 patients, were tested using the Gen-Probe Amplified Mycobacterium Direct Test™ (AMTD). After decontamination procedure, every sample was tested by AMTD and by culture on solid and liquid media. The "Gold-standard" was considered by the combination of culture results and clinical diagnosis. Tuberculosis was present in 17,59 % (208 patients). For theses 1538 non-respiratory samples (225 culture positive samples, 248 AMTD positive), 279 corresponded to tuberculosis. After resolving the discordant results, the sensitivity, specificity, positive and negative values were 89, 99, 99,6 and 97,3 %.
