[Analysis on the results of TB skin test in medical students].

Purpose: To obtain baseline, medical students are recommended to make two-step tuberculin skin tests when they are in good physical health, as the baseline information to detect later tuberculosis infection. We investigated a method to obtain appropriate baseline data, because the accurate method of this test was not yet established.

Subjects And Methods: The subjects were the tuberculin skin test results of 1066 medical students who were subjected to different methods of tuberculin skin test (58% tested once, 37% tested twice, and 5% tested three times).
