Intracutaneous Test

Intracutaneous or intradermal allergy testing is a method of skin testing that helps determine whether a person is allergic to a particular allergen. This test involves injecting a small amount of the suspected allergen under the surface of the skin. After about 20 minutes, it is checked whether there is a reaction in the area.

Intracutaneous Test

In general, three common methods of allergy skin testing are applied:

In the skin scratch test, a small amount of substance that can cause symptoms is placed on the skin, usually on the forearm, upper arm, or back. The skin is then scratched and the allergen gets under the skin surface. The skin is then closely checked for swelling and redness or other signs of a reaction. Results usually appear within 15-20 minutes. In this method, several allergens can be tested simultaneously. Allergens are substances that cause an allergic reaction.
In the intradermal test, a small amount of allergen is injected into the skin. Then the reaction on the skin is monitored. Although the first method is negative, if it is still thought that there is an allergy to the allergen, this method is applied.
In patch testing, potential allergens are taped to the skin for 48 hours. The cause of skin reactions that occur within 72 to 96 hours after the substance comes into contact with the skin is checked.

Mainly the advantages of intracutaneous testing are slightly better reproducibility and higher sensitivity. Intracutaneous (intracutaneous) tests are done using a hypodermic syringe and needle. Some devices have a single stylus with one or several points so that the application of the extract and the puncture take place in one step. Multi-head skin testing devices are first dipped into the extract bottles, then applied to the skin, completing the test in one step.

Intradermal test is a test applied in cases where the skin scratch test is negative but clinical findings are compatible with respiratory tract allergy, atopic dermatitis, bee allergy or drug allergy. Except for bee allergies, direct intradermal testing (intradermal testing) cannot be performed without a scratch test on the skin.
