Diagnosis

Phenotypic and molecular drug susceptibility testing (DST) available at select referral laboratories has been fully updated. Developed in partnership with national referral laboratory colleagues, the tool is an Excel file that contains detailed information for clinicians about the DST services available at 7 key referral laboratories in the U.S. The tool originates from the Laboratory chapter of Drug-Resistant TB: A Survival Guide for Clinicians (4th ed) and was last updated 5/5/26.

First released in 2004, the Guide is a joint publication of CITC and the Tuberculosis Control Branch of the California Department of Public Health. The Guide’s information and user-friendly tools can be used by any provider who participates in the management of patients with drug-resistant TB. Ten chapters cover major topics pertaining to epidemiology, diagnosis, laboratory issues, treatment, medications, pediatrics, co-morbidities and special situations, monitoring and case management, adverse reactions, and treatment of contacts.
