PPD RT23 is a tuberculin that is used worldwide. Korea has been using 1TU RT23 for its nationwide tuberculosis prevalence surveys at five-yearly intervals since 1965, and found a drop in its potency after the 1975 survey. This finding draws attention to the interpretation of tuberculin survey data observed with RT23 at different time periods.
