How do I know which type of syringe is right for my needs?

You can start by looking at the size and gauge of the needle. The size will vary depending on what you are injecting or drawing out of the body, while the gauge refers to the thickness of the needle. For example, a 25-gauge needle is thinner than a 27-gauge needle. Generally speaking, smaller needles are used when drawing blood and larger ones are used when administering drugs or fluids. Additionally, if you have any medical conditions or allergies, it's important to consult with your doctor before selecting a specific type of needle.
