The median cubital creates less bruising and pain than other draw sites. Within the antecubital fossa, this vein poses the least amount of risk.
What happens if you draw blood without a tourniquet?
Performing venipunctures without tourniquets is not an option. Constriction of the circulation causes veins to distend as they fill up with blood that can no longer circulate. Distended veins are easier to palpate and access.

What is the main reason for testing software before releasing it?
