We messured delayed cutaneous hypersensitivity reactions by Multitest CMI Kit. Total 209 normal adults ranging in age from 17 to 55 year(male 106, female 103) were tested. The results were obtained as follows ; 1. Sum of average diameter of positive antigens wss 20.7mm in male and 15.6mm in female. 2. Number of positive antigens was 3.9 in male and 3.4 in female. 3. Rate of anergy was 1.4%(0.9% in male, 1.9% in female). 4. The rate of subjects below warning score(below 10mm in male, below 5mm in female) was 2.8% in male and 5.8% in female. 5. Antigen with the highest response was tuberculin in both sex(male 95.3%, female 89.3%) and antigen with the lowest response was trichophyton(22.5%). 6. Aversge score of positive response of every antigens was highest in tuberculin at both sex(male 2.8mm, female 2,6mm) 7. Average score of total antigens with positive response was 5.5mm in male and 4.6mm in female. 8. The rate of false positive reaction to 70% W/V glycerine was 1.4% totally.
