RESUMO

The sensitivity and specificity of the Amplified Mycobacterium Tuberculosis Direct (AMTD) test, evaluated with 1,363 respiratory samples (128 from tuberculous patients), were 92.97 and 98.7%, respectively. When an equivocal zone (30,000 to 1,000,000 relative light units [RLU]) was used instead of a 30,000-RLU cutoff, the sensitivity and specificity of the AMTD test were 92.97 and 100%, respectively.
