This first step is essential.
This is what enables the allergist to determine the most likely diagnosis, the necessary investigations and the treatments to be considered.
A first treatment is immediately prescribed to relieve the patient.
These tests provide a rapid response, enabling confirmation of the diagnosis suspected during the initial consultation.
These tests are performed on most allergens that cause immediate reactions, and involve painlessly penetrating a very small quantity of allergen into the skin:
This test is used to assess the extent of allergic asthma andinflammation bronchial inflammation
It also enables you to monitor the progress and success of your treatment.
Allows, if necessary, to look for allergy antibodies: Immunoglobulin type E, and to look for the presence of eosinophils in the blood count.
The oral provocation test is performed with food or medication.
In reality, the oral provocation test is used to demonstrate the absence of allergy, in order to either reintroduce the offending product, or determine a replacement substance, as in the case of drug allergy, where we are looking for a possible antibiotic.
These tests are used to detect contact allergens responsible for allergic contact eczema. Tests can be prepared from suspected substances (cosmetics, etc.).
They involve putting the allergen in contact with the skin, and are read 3 days later.
Once the allergen has been identified, it can be avoided.
Depending on the patient’s medical history, clinical examination and investigations, appropriate treatment is proposed.
At this stage, we can decide whether desensitization is recommended.
