that little drop of blood is going to be used by your meter to give a reading that reflects the glucose/sugar in your body, so those test
strips and
meters are VERY sensitive to ANY presence of
glucose... so, if you have ANY residual sugar on your skin, the reading might be inaccurately high... if you have ANY residual water or oil or lotion on your skin, the reading might be inaccurately low...
Regardless, more importantly... how have your morning readings been?
