Abstract
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.
摘要
PPD RT23是一种在全球范围内使用的结核菌素。自1965年以来，韩国每隔五年就在全国范围内使用1TU RT23进行结核病患病率调查，并发现1975年调查后其效力有所下降。这一发现引起了人们对不同时期使用RT23观察到的结核菌素调查数据解释的关注。
