Venipuncture
The procedure of puncturing a vein with a needle to collect blood samples or establish intravenous access. A routine clinical task performed by phlebotomists and nurses, it supports diagnostic testing and pre-operative preparation across care settings.
What is venipuncture?
Venipuncture is the procedure of puncturing a vein with a needle, most often to collect a blood sample but also to establish an intravenous line. It is one of the most frequently performed clinical tasks and is carried out by phlebotomists, nurses, and other trained staff.
Performed correctly, venipuncture provides the blood specimens that diagnostic laboratory testing relies on, as well as a route for IV access when needed.
Why does venipuncture matter across care settings?
Venipuncture supports the diagnostic testing that informs nearly every area of clinical decision-making, from routine screening to disease monitoring. The quality of the draw directly affects the reliability of the results.
It also plays a role in preoperative preparation, supplying the lab work clinicians review before a procedure and supporting the establishment of IV access. As a routine task across clinics and surgical centers, it is a small but pervasive part of patient care.
