Finding a Vein


Choosing the Right Limb

    • Do

    • Use the nondominant arm if possible
    • Try to use the AC fossa where possible
    • Don't

    • Absolutely do not use the same arm as an AV fistula
    • Don’t use the same arm as a past lymph node dissection or mastectomy
    • Don’t use a limb affected by stroke
    • Don’t insert a needle through a burn, oedema, haematoma or infected tissue
    • If testing coags, do not take from the same limb as a heparin infusion
    • If an infusion is running, either stop the infusion prior to taking the sample or use another limb
