Tuberculin Reactions of the Hong Kong Chinese, with special reference to the use of Tuberculo-Protein
Published online by Cambridge University Press: 15 May 2009
Extract
1. The tuberculin reactions of 259 Hong Kong Chinese, mostly adults, were determined by the Mantoux method. Each individual was tested with various dilutions of both old tuberculin and tuberculo-protein.
2. Of 215 subjects above the age of twenty, 93·1 per cent, yielded positive reactions to old tuberculin in dilutions of 1/1000 or higher.
3. Tuberculo-protein compared with old tuberculin of similar dilutions did not yield such a high percentage of positive reactions, seldom produced such vigorous reactions and never caused vesiculation. (This may have been due to deterioration.)
