Extrapulmonary, meningitis

*Patient should be examined for evidence of current (active) pulmonary tuberculosis. If evidence exists, additional isolations are necessary

Skin-test (PPD) or interferon gamma release assay (e.g., QuaniFEron) positive with no evidence of active pulmonary disease
Pulmonary (suspected or confirmed) OR laryngeal disease

AFB smear positive:
Min 14d tx and meets discontinuation criteria
AFB smear neg, high suspicion and started on therapy:
Min 5d tx and meets discontinuation critera;
AFB smear neg, low suspicion and not on therapy:
meets discontinuation criteria

Collect 3 separate AFB sputum obtained at 8-12 hr intervals (at least 1 specimen must be in early AM).  See

2. Environment of Care Manual for Aerosol Transmissible Disease Exposure Control Plan.

Discuss with HEIP before discontinuing airborne isolation

AFB smear-positive:

• AFB smear negative x 3 AND
• Clinically improving 

AFB smear-negative:
• At least 5 days of anti-TB treatment AND
