Allergenic Extract

In each subject, a drop of each of the 3 concentrations of the allergenic extract, in addition to the positive control (histamine) and the negative control, will be applied. The application will be duplicated on the subject's anterior forearm, with a distance of approximately 4 cm between each application to avoid overlapping reactions and false-positives results.
