The act, practice, or medical procedure of opening or puncturing a vein to withdraw blood.

Usually refers to blood collection for diagnostic testing or donation, but can also be a therapeutic treatment for conditions like hemochromatosis.

The story behind the word. The word comes directly from ancient Greek medical traditions where 'cutting a vein' was believed to cure illnesses by releasing excess blood. Today, we no longer cut veins to balance humors, but the name remains for the precise, sterile science of drawing blood.
