Soybean is one of items having a high rate of dependence on imports in our country among GMOs (Genetically Modified Organism) developed by the gene recombination technique recently used for efficient plant breeding. Soybean is used widely as main materials in various processed foods, various industrial basic materials, and domestic feed s tuffs. According to report from abroad, soy bean ingredient cause serious allergy. But we haven't studied enough in the induction of food allergy by soybean and its safety even though we are now under the great effect of GMO soybean. In this study, the inducible possibility of allergic reaction to GMO soybean, which has different structure from natural soybean, was investigated. Among studies of allergen, we examined allergic reaction of GMO and natural soy bean through Double Blind Placebo Controlled Food Challenge Test (DBPCFC). We also examined skin reaction by skin prick test reagent and self-made patch test reagent, but as the result of this test, the difference between the results from GMO and natural soybean was not founded precisely. But comparing with the result of skin prick test and patch test in GMO and natural soybean, in both tests it was showed that the accuracy of self-made reagent was higher than that of the other. And in soy bean antigen specific IgE test and skin prick test to immune serum separated from blood of subject group on the base of result of DBPCFC test, it was also showed that the accuracy of skin prick test by self-made reagent was higher. As a result of the study of rate of DBPCFC positive reaction to GMO and domestic natural soybean in an age, it was founded that the older one grow, the higher rate of positive reaction to both soybean was but there was no difference between GMO and domestic natural soybean. But since the introduction period of GMO soybean In this country isn't long enough, study must be continued concerning the safety of it.
