This study evaluates the influence of the extent of disease on the size of the tuberculin reaction in 150 untreated patients of pulmonary tuberculosis. 121 of these patients reacted to 1 TU of PPD. 13 of the 82 moderately advanced and 15 of the 64 far advanced cases had an induration of 0-11 mm. In the strongly positive (18mm. & over) range, there were 38 out of 82 moderately advanc-ed cases, as against 22 out of 64 cases of far advanced disease. The difference in the distribution of the tuberculin indurations between the two groups is not statistically significant.
