ALTERNATE SITE TESTING (AST)
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 results from sites other than your
fingertip could be significantly different due to blood glucose levels changing rapidly
after a meal, insulin, or exercise.
Consult with your diabetes healthcare professional prior to testing from a site other
than your fingertips.
Results obtained from sites other than the fingertip may differ significantly as is the
case with all blood glucose monitoring systems. Rapidly changing results are likely
to occur after eating. Insulin dosing and physical activity are shown in the fingertip
more quickly than in alternate sites.
