Consider collection of induced sputum for patients that are unable to produce good quality specimens or for whom bronchoscopy is not appropriate
Specimens should be of good quality; ask to recollect if lab reports specimen of poor quality
When interpreting AFB result, consider possible influence of previous/concurrent antibiotic use (e.g. Moxifloxicin)
Ask to collect post-bronchoscopy specimen. Label as “post-bronchoscopy specimen " or lab not to reject if < 8hrs since previous specimen
