How often you test is best decided by you and your healthcare professional. It may vary according to your age, the type of diabetes you have, any medication you are using, whether you are ill, and any physical or emotional changes in your life. Because a variety of factors impact blood glucose levels, target ranges are different for different people. Your health care professionals can help you set realistic target levels for your own diabetes management. Wash your hands with soap and warm water, and dry them thoroughly.
Warm water stimulates the flow of blood to the fingers.
Hanging your arm down at your side for 10-15 seconds before the finger stick will also help. If you use alcohol to clean your finger, make sure it dries before pricking your finger. Choose a different spot on the side of a finger each time you test. Repeated punctures in the same spot can make your finger sore and callused. Avoid pricking your fingertips.
