The 21 gauge is a smaller needle.
I draw it with 18 and inject with 22 if mixed with Haldol or diluted. I use 21 if undiluted.
Butterfly needles come in several gauges - 21, 23, and 25-gauge.
21 gauge
21 or 22 gage
usually the veinipuncture is using a 21 or 22 gauge needle at about a 30 degree or less angle.
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)
a 25 Gauge needle is capable of drawing blood, but i would go with 21 or 23 for withdrawing lots of blood simply because the 25 gauge could get clogged..
21 gauge, thin-wall 1-1/2 inch needle

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.
