Blood drawing techniques

Blood drawing, or venipuncture, involves inserting a needle into a vein, usually in the arm, to collect a blood sample. The process begins with cleaning the area to prevent infection, then applying a tourniquet to make the vein more visible. A skilled technician inserts a sterile needle into the vein, collects the blood into vials, then removes the needle and applies pressure to stop bleeding. Proper technique ensures minimal discomfort and accurate results, emphasizing patient safety, hygiene, and comfort throughout the procedure.
