Recommendations for Responding to Tuberculin Shortages
· If available and appropriate, screen for LTBI with an Interferon Gamma Release Assay (IGRA) (T-SPOT®.TB and QuantiFERON® Gold in-tube) instead of a tuberculin skin test (TST).
· Prioritize TSTs if necessary. High priority groups include:
o Contacts to a person with pulmonary or laryngeal TB
o Persons who are immuno-compromised
o Evaluation of persons with symptoms suggestive of TB disease
· If necessary, defer annual screening of employees, residents, and/or inmates as part of an infection control plan until sufficient tuberculin becomes available.
