If it is positive, after about 30 minutes, redness appears on the skin, sometimes with blisters.
intradermal tests. This study helps to get more accurate results. To find out the body’s reaction to a particular allergen, its solution is injected into the surface of the skin. As a result, a bubble is formed (up to about 4 mm in size). The first reaction appears after 20 minutes, the full result becomes apparent within a day.
provocative tests. Helps diagnose allergy to inhalant allergens. A solution of the suspected allergen is sprayed into the nasal cavity and the reaction is observed. It is important to know that such a study can be carried out exclusively in a hospital, in no case should you do it yourself.
Blood test for specific immunoglobulins E. Allergy to household, pollen, food and other allergens is accompanied by the appearance of class E antibodies (immunoglobulins — Ig) in the blood. In patients with allergic diseases, the level of specific IgE antibodies is sharply increased.
