Allergic Skin Test is fundamental method for the diagnosis of the allergic disease. But studies of distribution of skin reactivity in normal children are not sufficient and variable positive criterias are difficult to interprete the allergic skin test. A study was performed to investigate the skin reactivity of apparently healthy students to D. Pteronyssinus during the period of May to June 1996. Subjects were selected from students attending to 6 grade of primary school in Taejeon and healthy assessed by health questionairs, 318 in total number, 178 in boys and 140 in girls. The results were summarized as follows : 1) In skin reactivity by Histamine, the mean sheal values were 3.28±1.70mm, the mean erythema values were 11.36±8.64mm. 2) In skin rectivity by D. Pteronyssinus, the mean when and erythema values were 1.88±3.41mm, 5.52±10.1mm respectively and the wheal showing under 2.9mm was of 75.2%, the erythema under 9.9mm was of 77.3%. 3) In skin reactivity by D. Pteronyssinus, cases showing above 3.0mm wheal and above 10 mm erythema encountered in 22.0%, those showing above 5.0 mm wheal and above 20mm erythema encountered in 13.2%. 4) the positive rate of the above 2+ was 26.7%.
