A 21-gauge needle is commonly used for drawing blood for a chemistry profile. This size balances the need for sufficient blood flow while minimizing discomfort for the patient. However, a 22-gauge needle may also be used, depending on the patient's veins and specific laboratory requirements. Always ensure to follow your facility's protocols for blood draws.

What needle gauge is used on the typical patient for a chemistry profile?

Depends how it is drawn- Butterfly or straight stick 19 g and 21 G are the normal straight stick. If you use a buterfly to draw the lab then they are ususally 21 or 23 Gauge. (Remember the bigger the gauge number the smaller the needle width). The smaller the needle width the higher the chance of hemolization (cell squishing)
