intradermal test


Also found in: Dictionary, Thesaurus, Legal, Financial, Encyclopedia.

skin test

a method for determining induced sensitivity (allergy) by applying an antigen (allergen) to, or inoculating it into, the skin; induced sensitivity (allergy) to the specific antigen is indicated by an inflammatory reaction of one of two general kinds: 1) immediate, appears in minutes and is dependent on circulating immunoglobulins (antibodies); 2) delayed, appears in 12-48 hours and is not dependent on these soluble substances but on cellular response and infiltration.
Synonym(s): cutaneous test, intradermal test, skin reaction

intradermal test

n.
A test for hypersensitivity or allergy in which a small amount of the suspected allergen is injected into the skin.

A method for determining induced sensitivity (allergy) by applying an antigen (allergen) to, or inoculating it into, the skin; induced sensitivity (allergy) to the specific antigen is indicated by an inflammatory reaction of one of two general kinds: 1) immediate, appears in minutes to an hour or so and in general is dependent on circulating immunoglobulins (antibodies); 2) delayed, appears in 12-48 hours and is not dependent on these soluble substances but on cellular response and infiltration.
Synonym(s): intradermal test.

Intradermal test with one single dilution: Usually a 1:1000 weight/ volume dilution of the allergen is injected, and if reactive, the result is considered positive.
Allergy and immunotherapy
[11] Prick tests are superior to scratch tests because they are more sensitive, more reproducible, and correlate better with intradermal tests. [12] They can be performed in a variety of ways, but the type of testing greatly influences the results.

Occasionally, if intradermal tests reveal an allergy to a specific agent, hyposensitization, by injecting increasing amounts of the allergen, may lead to a cure.

"Prick" test and intradermal tests should be performed in reactions which occur in the first hour and intradermal patch test should be performed in reactions which occur after one hour.

We recommend intradermal testing over skin-prick testing as there have been several cases (21) involving negative skin-prick results to blue dyes, when subsequent intradermal tests were positive.
