title: [Comparative assay between PPD-Rt 23 and PPD-T in a school population (author's transl)].
abstract: 226 students of both sexes from 12 to 14 years old were examined for tuberculin hypersensitivity with PPD-Rt 23 and PPD-T antigens. Strong reactions (greater than or equal to 10 mm diameter) were noted in 25,2 and 23,5% of the population, respectively. Individuals showing a weak or no reaction to PPD-Rt 23 had a weaker reaction to PPD-T, but those with a strong reaction to PPD-Rt 23 had an equivalent reaction with PPD-T.
