Yes, I do so weekly. Use a 22 or 23 gauge needle to draw the test, then switch to the 27 gauge 1.25 inch needle. I heart the loaded syringe on a heating pad for about 10 minutes to loosen up the oil, then inject. Much less pain than a larger needle.
Usually 24 number needle is used by doctors. For baby you can use 26 number needle and for oily injections you can use 22 number needle.
the gauge is the measurement of how big around the stud or needle is

Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.
Yes, the larger the gauge the smaller the needle size.
