INTRADERMAL TEST Meaning and
Definition
-
An intradermal test is a medical procedure used for allergy testing, specifically designed to identify substances that may cause an allergic reaction. The main purpose of this diagnostic test is to determine the presence or absence of allergies in an individual.
During an intradermal test, a small amount of the suspected allergen is injected into the superficial layer of the skin, typically on the forearm or the back. The substance is administered using a fine needle or syringe. Once injected, the presence of an allergic reaction is assessed by observing the skin's response. The test measures the skin's sensitivity and reaction to the allergen.
After the allergen is introduced into the skin, the individual's immune response is triggered. If the person is allergic to the substance, a raised bump or skin reaction known as a wheal will appear. The size of the wheal can indicate the severity of the allergy. A positive result suggests that the person is sensitized to the allergen and may experience an allergic reaction when exposed to it in the future.
Intradermal tests are commonly used to diagnose allergies related to medicines, certain foods, insect venom, or environmental factors like pollen or dust mites. This type of allergy testing is more sensitive than other methods, such as skin prick tests, as it can detect allergies to substances that may not produce a reaction through other means.
It is essential to conduct an intradermal test under the supervision of an experienced healthcare professional or allergist to ensure accurate results and proper interpretation of the test outcomes.

Etymology of INTRADERMAL TEST
The word "intradermal" is derived from two Latin roots - "intra" meaning "within" or "inside" and "dermis" referring to the second layer of the skin. "Intradermal" is commonly used in medical terminology to indicate a procedure or method that involves injecting a substance into the dermis layer of the skin.
The word "test" comes from the Old French word "test" or "teste" meaning "an examination" or "trial". It can be traced back to the Latin word "testum" which means "earthen pot" or "witness".
Therefore, the term "intradermal test" refers to a medical diagnostic technique where a substance is injected into the dermis layer of the skin to evaluate a person's immune response or sensitivity to that particular substance.
