  • Radial
  • An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , but sometimes the femoral artery in the groin or another site is used. (wikipedia.org)
  • Blood is most commonly drawn from the radial artery because it is easily accessible, can be compressed to control bleeding, and has less risk for occlusion. (wikipedia.org)
