Can you give blood through a 22-gauge?

23 Gauge Needles
23g needles, also known as butterflies, are used when a person’s vein is much narrower than average. It is light blue color coded. Despite the phlebotomist’s efforts to anchor the vein, the patient may be unwell or have minimal sites to choose a vein from, requiring a smaller needle.
What does gauge mean in needles?
The gauge size of a needle indicates what the diameter of the lumen (opening) is. The higher the gauge, the smaller the diameter. For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle. Different companies use different measurements for gauges, so it is important to specify inner diameter.
