This analysis begins with a questionnaire (anamnesis) to confirm the existence of allergy and detect the allergens that may be responsible for the observed symptoms. Following anamnesis and a physical examination, a diagnosis of the disease, based on a series of skin tests, will determine the underlying cause. In some cases, the specialist may consider that challenge tests are needed.

LETI Pharma offers various products for in vivo diagnosis of allergic diseases based on both skin and challenge tests.
