Description
Summary:Abstract INTRODUCTION The teste rápido molecular para tuberculose (TRM-TB) was introduced in 2014 in Brazil for tuberculosis screening. However, its role in adolescents in Brazil has not been studied. METHODS A descriptive study of adolescents with suspected tuberculosis using National Laboratory software. RESULTS Of 852 (15.4%) suspected cases, 131 were positive by TRM-TB and 2% were resistant to rifampicin. Among TRM-TB-positive cases, 105 (91.4%) were culture-positive. Sixty-four of 96 samples were sensitive to rifampicin by TRM-TB; 11 were resistant to other drugs by drug sensitivity test (DST). CONCLUSIONS Among suspected cases, 16% were diagnosed by TRM-TB, of which 17% were drug-resistant by DST.
