Every phlebotomist hopes to see large, prominent veins that are easily visible just below the surface of the skin. Veins with an elastic (sometimes described as a 'bouncy') quality usually indicate large, healthy veins that are less likely to collapse. The medial cubital or cephalic veins are the most common veins used in venipuncture. Veins which are fibrosed, fragile or inflamed should be avoided.

Superficial vein is a term used to describe a vein that is close to the surface of the body. It is used to differentiate veins that are close to the surface from veins that are far from the surface, known as deep veins. Superficial veins are important physiologically for cooling of the body. When the body is too hot the body shunts blood from the deep veins to the superficial veins, to facilitate heat transfer to the surroundings. Superficial veins can be seen under the skin.
