Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To do so, investigators invited laboratory workers who presented any symptoms in presence of drosophila to undergo skin prick tests in order to determine if a specific sensibilization to drosophila exists. Then, a blood sample is taken from these persons to research specific IgE directed against drosophila. By this way, investigators hope determine if a specific allergy to drosophila exists, its characteristics as prevalence, symptoms, populations concerned...in order to better protect laboratory workers and prevent allergy incidence.
