Q: Question: Does adequately washed bronchoscope induce false-positive amplification tests on bronchial aspirates in the diagnosis of pulmonary tuberculosis?
Answer: Adequately cleaned and disinfected bronchoscopes did not cause false-positive amplification test results for M tuberculosis on bronchial aspirates by cross-contamination. Furthermore, sensitivity was greater with the CA tests. Therefore, CA tests on bronchial aspirates seem to be useful in the diagnosis of pulmonary tuberculosis.
A:
no
