What is the abbreviation for the intradermal route?

The abbreviation for the intradermal route is "ID." This route involves the administration of a vaccine or medication into the dermal layer of the skin. Intradermal injections are often used for certain vaccinations, such as the tuberculosis (TB) test or dermatological treatments, as they allow for a controlled immune response and can be particularly effective for research or testing applications.

The other options represent different routes of administration: "IM" stands for intramuscular, "Sub-Q" refers to subcutaneous, and "PO" means per os or orally. Each of these routes has specific applications and absorption characteristics, making it important to use the correct abbreviation to ensure clarity in medical communication and practice. Understanding these abbreviations helps healthcare providers choose the appropriate method for administering vaccines and medications based on the treatment plan.
