What does venipuncture mean?
Venipuncture is the medical practice of puncturing a vein, usually to draw blood for a laboratory test or to introduce a substance such as medication or fluid. The term is chiefly used in clinical and healthcare contexts, and it names either the procedure or, occasionally, the puncture site itself. During a venipuncture, a trained professional identifies an appropriate vein and inserts a needle, often with the help of a tourniquet; the process may be routine or more complicated in people with difficult-to-access veins. The word conveys technical precision rather than the older, broader sense of bloodletting associated with “phlebotomy.” It is useful in medical records, instructions, and reports because it identifies the specific act of entering a vein, distinguishing it from an injection into muscle or skin. Although often informally called a blood draw, venipuncture is more exact, particularly when the method of needle placement matters.
