NCT00805402

Brief Summary

The aim of this study is to show that flow cytometry can be an accurate tool to help physicians regarding the diagnosis, the SIT decision and the SIT arrest of hymenoptera venom allergy. 75 patients having a story of reaction to hymenoptera venom will be selected for this trial. Blood samples will be analyzed at: inclusion visit, Week 1 visit, Week 3 visit, Week 10 and Week 21 visit.
