Allergies: sensitivity tests

The diagnosis of allergy is not as obvious as it seems. All allergies are not as easy to detect as classic hay fever, especially in young children. That's why it is better to consult a specialist, an allergist doctor.

To complete these investigations, blood tests can quantify the cells linked to the allergic response. Finally, other provocative or reintroduction examinations may also be performed.
