A needle with a size of 0000 (4 zeros), also known as a 0000 gauge needle, has the largest diameter. These needles are typically used for thick materials like leather or heavy-duty fabrics.

The difference between dry chemistry analyzer and the chemistry analyzer is the reagents used.
The needle length typically used for intradermal injections is 1/4 to 1/2 inch. This shorter length allows for precise and shallow delivery of medication into the dermis layer of the skin. It is important to use a smaller gauge needle (higher number) to reduce pain and trauma during the injection.
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)

Mine was done with a 16g needle (:
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.
needle- is used for sewing.
Medical procedures
In a needle cricothyroidotomy, the doctor uses a 12- or 14-gauge catheter and needle assembly.

A green-top tube containing lithium heparin or a red-top tube without anticoagulant are commonly used for collecting blood samples for a chemistry profile.
Medical uses, scientific uses, piercing uses.
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.
None, 23 gauge is used for injection medications and is too small for any type of piercing.
