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.:
- Centers for Disease Control and Prevention
- California Department of Public Health (CDPH)
- Florida Health Public Health Laboratories
- Johns Hopkins University
- Mayo Clinic Laboratories
- National Jewish Health
- Wadsworth Center, New York State Department of Health
The first tab of the tool features a one-page “At-a-glance” table that summarizes the DST services available at each laboratory for most medications used to treat tuberculosis. Subsequent tabs specify the phenotypic and molecular testing offered by each referral laboratory and information about how to order tests.
Annual updates will be coordinated with the laboratories and posted.
The tool first appeared in the 2022 edition of Drug-Resistant TB: A Survival Guide for Clinicians, in the Laboratory chapter. The Guide is a joint project of CITC and CDPH; the 4th edition will be released online on a chapter-by-chapter basis from 2026 to 2028.
