The foreign-born population is disproportionately affected by tuberculosis (TB). Testing to identify persons with latent TB infection is critical. The aim of this study was to assess clinic-based testing for latent tuberculosis infection among recent Asian and Latino immigrants. A randomized controlled trial of interpreting methods and their impact on medical outcomes was conducted at the primary care clinic of a New York City municipal hospital. This study is a nested cohort of recruited patients with an indication to receive tuberculin testing, based on recent migration to the US from endemic areas. Medical record data were abstracted to determine referral for, and completion of, tuberculin testing. Bivariate analyses were used to test for differences in tuberculin testing between language concordant and discordant groups. Seven hundred and eighty-two patients were enrolled. One hundred and ninety-one had migrated within 5 years of enrollment from endemic areas. None spoke English as a primary language. Seventy percentage of patient-provider encounters were language discordant. Seventeen of 191 were referred for testing. Fifteen (88%) completed testing. Six (40%) had positive results. There were no significant differences between language concordant and discordant patients. In this at-risk population, every patient in clinical care should be considered for testing if indicated by country of origin. © 2010 Springer Science+Business Media, LLC.
