What is the typical size of an intradermal syringe?

The typical size of an intradermal syringe is 1 mL. This size is ideal for intradermal injections, which require the administration of small volumes of medication (usually less than 0.5 mL) directly into the dermis layer of the skin. Using a 1 mL syringe allows for precise measurement and accurate delivery of the medication, which is crucial in processes such as allergy testing and tuberculosis screening where sensitivity to dosage is highly important.

Intradermal injections involve using a small needle to create a small bleb beneath the skin, and a 1 mL syringe is specifically designed to accommodate this need without excessive volume that could lead to complications or inaccurate readings of reactions. In contrast, larger syringes such as 3 mL, 5 mL, or 50 mL are typically used for intramuscular or intravenous injections where larger volumes are often required. Thus, the 1 mL syringe is the appropriate choice for intradermal administration.
