Brief Summary

Allergy is a very common problem and can be a handicap in everyday life, specially when symptoms occur at work place. Some persons working with drosophila developed respiratory symptoms. Investigators tried to analyze if these manifestations could be due to a specific allergy to drosophila.

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

    The day of inclusion

Secondary Outcomes (1)

  • Survey to analyse risk factors for allergy to drosophila

    The day of inclusion

Study Arms (1)

laboratory workers with symptoms in presence of drosophila

OTHER
Other: blood test (four dry tubes 7ml) and prick tests

Interventions
