Important Information About AST: Sites other than your fingertip may have
fewer nerve endings so obtaining a blood sample from these sites may be
less painful. The technique for alternate site testing is different from fingertip
testing. Blood glucose testing results from sites other than your fingertip could
be significantly different. Physiological differences in circulation between the
fingertip and palm may result in differences in blood glucose measurements
between these sites. Differences in glucose concentrations may be observed
after eating, taking insulin medication, or exercise and are typically shown
more quickly in the fingertip than in the palm. Consult with your diabetes
healthcare professional prior to testing from a site other than your fingertips.
