ID stands for which injectable abbreviation?

• A. Intramuscular Abbreviation
• B. Subcutaneous Abbreviation
• C. Intravenous Abbreviation
• D. Intradermal Abbreviation

Answer: (D)

ID stands for intradermal. This route places medicine into the dermal layer, just beneath the outer skin, so the injection sits very shallowly under the epidermis. It’s often used for tests that rely on a local immune response, like the tuberculin skin test (Mantoux) and certain allergy tests. When done correctly, you’ll see a small raised wheal or bleb at the injection site, indicating the substance is in the dermis. Key technique notes: use a very shallow angle (about 10–15 degrees) and a tiny volume, typically around 0.01–0.1 mL. A small-gauge needle is used (commonly around 26–27 gauge, about 3/8 inch long). This combination keeps the injection just under the skin surface, rather than into muscle or fat. This differs from intramuscular injections, which go into muscle with larger volumes and deeper needles; subcutaneous injections, which go into the fatty tissue at a shallow depth but not within the dermis; and intravenous injections, which are delivered directly into a vein for rapid absorption. The dermal placement is what makes the intradermal route distinct.
