There are a few ways you can improve blood flow and make blood sugar testing easier: Warm your fingers by washing with warm, soapy water, then rinse and dry completely. Let your arm hang down at your side to increase blood flow to the fingertips. Grasp finger just below the joint closest to the fingertip and massage gently toward tip of finger, then squeeze for 3 seconds. Use an Accu-Chek lancing device set to the right penetration depth for your skin type. Refer to your user guide for additional information.
