MeSH | D007271 |
Intradermal injection (also intracutaneous or intradermic, abbreviated as ID) is a shallow or superficial injection of a substance into the dermis, which is located between the epidermis and the hypodermis. For certain substances, administration via an ID route can result in a faster systemic uptake compared with subcutaneous injections,[1] leading to a stronger immune response to vaccinations, immunology[clarification needed] and novel cancer treatments, and faster drug uptake.[2] Additionally, since administration is closer to the surface of the skin, the body's reaction to substances is more easily visible.[1] However, due to complexity of the procedure compared to subcutaneous injection and intramuscular injection, administration via ID is relatively rare, and is only used for tuberculosis and allergy tests, monkeypox vaccination,[3] and certain therapies.[which?]
