Sensitivity of AMPLICOR MTB on direct detection of Mycobacterium tuberculosis in smear-negative specimens from outpatients in Rio de Janeiro
We evaluated the performance of the AMPLICOR MTB assay for detection of M. tuberculosis in clinical specimens obtained from 98 smear-negative tuberculous patients (43 with positive and 55 with negative culture results). The sensitivity of the AMPLICOR MTB was 44.9% (44/98) and that of culture was 43...

Summary: | We evaluated the performance of the AMPLICOR MTB assay for detection of M. tuberculosis in clinical specimens obtained from 98 smear-negative tuberculous patients (43 with positive and 55 with negative culture results). The sensitivity of the AMPLICOR MTB was 44.9% (44/98) and that of culture was 43.8% (43/98). No significant difference was observed between the results obtained by AMPLICOR MTB and by culture. We conclude that amplification assays could be used for testing smear-negative specimens because a rapid diagnosis will benefit those patients.
A sensibilidade do kit AMPLICOR MTB foi avaliada em 98 espécimes clínicos baciloscopia negativa (43 eram cultura-positiva e 55 cultura-negativa) provenientes de pacientes ambulatoriais. A sensibilidade do AMPLICOR MTB foi de 44% (44/98) e a da cultura 43,8% (43/98). Não foi observada diferença significativa entre os resultados dos dois métodos. Conclui-se que os ensaios de amplificação podem ser utilizados em espécimes baciloscopia negativa, porque um rápido diagnóstico beneficiará esses pacientes. |
