A blood collection needle is a small syringe that is used to draw blood samples. These needles can be found in various sizes. The phlebotomist will need to determine which size is best suited for the patient's vein.

The most common needle type used is the 21g. This is a standard gauge for adult patients with average-sized veins. Unlike other sizes, the 21g needle is able to deliver a steady blood flow without causing discomfort to the patient. The needle also ensures the integrity of the specimen.

Another type of needle is a multi-sample needle. These types of needles are designed for easy connection to rubber stoppers and allow for several blood samples to be collected with a single puncture. They also have sharp edges that reduce the pain that occurs during the insertion process.

A winged needle is the preferred method for collecting blood for infants, children, and adults with small veins. They are typically color coded for easy identification. They are routinely used by pediatric and elderly patients. They also come with a collection bag attached. They are available in both standard and child sizes.

These needles are not only comfortable to use, but are made from high-quality materials. They also feature safety features, such as an integrated safety mechanism that retracts the needle when activated.
