Positioning the hand for venipuncture

Place the patient's hand slightly downward, with the top of the hand toward the phlebotomist. Fingers of the patient's hand are wrapped around the phlebotomist's hand to anchor the vein.

Vein puncture avoidance

Do not puncture veins where they branch (junctions) or the underside of the wrist, fingers, or top of the wrist, to prevent striking nerves, tendons or arteries.

Patient identification method

Use at least two unique identifiers to confirm patient identity: first and last name and an additional identifier, e.g., date of birth, medical record number.

Patient arm position

Support the patient's arm on a firm surface; the arm should be held in a downward position before venipuncture.
