What color is used for a 23 gauge needle?

A 23 gauge needle is identified by its blue color. In the world of phlebotomy and medical procedures, the color coding of needles is standardized to allow for quick identification of the needle gauge without needing to inspect the needle closely.

The gauge number indicates the diameter of the needle; a higher gauge number, such as 23, signifies a thinner needle. In this system, blue is consistently associated with a 23 gauge needle, making it easier for phlebotomists and medical professionals to select the appropriate needle for venipuncture or other procedures.

The use of color coding not only helps in identification but also contributes to safer practices, as clinicians can quickly ascertain the size of the needle they are working with, reducing the risk of errors during blood draws or injections.
