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.
