Outcome Measures
Primary Outcomes (1)
Number of participants with positive prick test to drosophila
Prick tests : measuring the size of the skin reaction (wheal) after prick tests with drosophila. A wheal measuring more than 4 millimeters in diameter sign a sensitization to drosophila. Then, a blood sample is collected in order to measure specific drosophila IgE rate
