Word: Intradermal Test

Definition: An intradermal test is a type of skin test used to check for allergies. In this test, a small amount of a substance that might cause an allergic reaction (called an allergen) is injected just under the surface of the skin.

Usage Instructions:

• When to Use: The intradermal test is usually done when a doctor wants to see if a person is allergic to something specific, like pollen, certain foods, or medications.
• How It Works: A healthcare professional will use a small needle to inject the allergen into the skin. After a short time, they will check the area for any reaction, such as redness or swelling.

Example:

• "The doctor performed an intradermal test to determine if Sarah was allergic to penicillin."

Advanced Usage:

• In medical contexts, the term "intradermal" can also refer to other types of tests or procedures that involve injections into the skin, not just allergy testing.

Word Variants:

• Adjective: Intradermal (e.g., "intradermal injection")
• Noun: Intradermal testing

Different Meaning:

While "intradermal" refers specifically to something being done within the skin (intra- meaning "within" and dermal relating to the skin), it is primarily used in medical contexts.
