Venipuncture is a medical procedure used to access a vein for various purposes, such as drawing blood or administering medications. It typically involves using a sterile needle to puncture the skin and enter a vein, usually in the arm. This procedure is commonly performed by healthcare professionals, including nurses and phlebotomists. The process begins with identifying a suitable vein, often in the antecubital fossa, and cleaning the area to prevent infection. After inserting the needle, blood can be collected into vials or tubes for laboratory testing. Proper technique and safety measures are essential to minimize discomfort and complications.
