intracutaneous test
LowTechnical/Medical
Definition
Meaning
A medical diagnostic procedure where a small amount of substance is injected into the skin to assess the body's immune reaction.
A method for detecting allergies or immunity to specific antigens, such as for tuberculosis (Mantoux test) or various allergens, by observing the localized skin response (e.g., induration, erythema).
Linguistics
Semantic Notes
Refers specifically to the injection method, as opposed to a scratch or patch test. The reaction is read at a specific time (e.g., 48-72 hours).
Dialectal Variation
British vs American Usage
Differences
Terminology is identical in both dialects. 'Intracutaneous' is a standard medical term. In less formal clinical contexts, 'intradermal test' is a perfect synonym used in both regions.
Connotations
None. Purely technical, clinical.
Frequency
Slightly more common in US medical literature, but 'intradermal test' is the overwhelmingly preferred term globally.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить дословно как 'внутрикожный тест' без контекста, так как в русском медицинском языке стандартным термином является 'внутрикожная проба'.
- Не смешивать с 'подкожной пробой' (subcutaneous).
Common Mistakes
- Misspelling as 'intercutaneous' or 'intracutanous'.
- Confusing it with a subcutaneous injection, which goes into the tissue *under* the skin.
- Using it as a general term for any skin allergy test.

FAQ
Frequently Asked Questions
No. A skin prick test places antigen on the skin surface which is then pricked, while an intracutaneous test involves injecting the antigen into the dermis.
A positive reaction typically shows a raised, firm bump (induration) and sometimes redness (erythema) at the injection site after 48-72 hours.
It detects a cell-mediated immune response to tuberculin, indicating past or present infection with TB bacteria.
No, it is a specialised medical term. Most people would simply refer to a 'TB test' or 'allergy skin test'.
