Potency of old tuberculin together with purified tuberculin (PT) which have been in use in japan was compared with those of Denmark, Sweeden, Norway, England and of America. Comparisons were done on both animal and human following the method described under the potency test of the minimum requirements for the diluted old tuberculin to be used in Mantoux test.<BR>The findings of the comparisons are shown in the tables from which it has been concluded as follows:<BR>1. The potency of Japanese OT was found to be equivalent to those used in Denmark, Norway, England and America, however, the one used in Sweeden was found to be slightly lower.<BR>2. The potency of our UT in a dilution of 1: 2, 000 (0.05 mg/0.1 ml) was found to be equivalent to the 5 TU (0.1 γ/0.1 ml) of PT used in Denmark.
