We conducted a retrospective comparative study of acid-fast bacilli (AFB) smear sensitivity according to time of specimen collection to assess whether three consecutive AFB smears collected in 1 day are useful when deciding to discontinue respiratory isolation of patients with pulmonary tuberculosis (TB). A total of 236 sputum specimens from 119 patients with pulmonary TB were used for the analysis. There was no statistical difference in AFB smear sensitivity of early-morning sputum and those collected later (P = 0.186). This may allow us to collect all specimens in a single day and discontinue respiratory isolation of TB patients earlier.
