Abstract:
The aim of this study was to compare the biological response obtained with two tuberculin tests--PPD-RT 23 and PPD derived from BCG--among children already vaccinated with the Calmette-Guérin bacillus. Results varied widely, and the differences observed were statistically significant. This shows the need for additional studies to assess the sensitivity, specificity and predictive value of both tests.
