Please Read the Following:
[1] Severe dehydration and excessive water loss may yield
inaccurate results. If you believe you are suffering from severe
dehydration, consult your healthcare professional immediately.
[2] Results below 70 mg/dL may mean low blood glucose levels
(hypoglycemia).
[3] Results over 240 mg/dL may mean high blood glucose
levels (hyperglycemia). Checking ketones may be advisable.
[4] If you get results below 70 mg/dL or above 240 mg/dL and
do not have symptoms of hypoglycemia or hyperglycemia, re-
peat the test. If you have symptoms, or continue to get results

forearm are alternate, but less
accurate, test sites. Only select soft
and fleshy areas to lance. Avoid
lancing any bony areas, obvious
veins and moles. Physiological
differences in circulation between
the fingertip, palm (at the base
of the thumb), and forearm
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.
Changes in blood glucose may be detected in
the fingertips before the palm (at the base of the
thumb) and forearm.
It is recommended that you use a ngertip sample if:
[1] You are testing for hypoglycemia or if you suffer from
hypoglycemia unawareness,
[2] You are testing your blood glucose within 2 hours of
eating, taking insulin, diabetes pills, exercise, or
[3] Your blood glucose results obtained from the palm (at the
base of the thumb) or forearm are not consistent with the way
you feel.
CAUTION: Please read all the instructions provided in this
owner’s guide and practice the testing procedures before
using the WaveSense Presto Blood Glucose Monitoring
System. Blood glucose monitoring should be done under
the guidance of a healthcare professional.
The WaveSense Presto System should be used:
[1] For measuring blood glucose levels from fresh capillary
whole blood samples taken from the fingertips, palms (at the
base of the thumb), or forearms.
[2] With WaveSense Presto Test Strips and WaveSense Control
Solution only. Use with other unapproved test strips or
control solution will void the manufacturer’s warranty and
will lead to inaccurate results.
[3] Outside of the body (i.e., in vitro diagnostic use only).
Do not use the WaveSense Presto System for:
[1] The diagnosis of diabetes.
[2] Testing the glucose levels of neonates.
[3] Testing glucose levels of arterial or venous blood.
[4] Testing glucose from sites other than the fingertip, palm
(at the base of the thumb), or forearm.
Possible test sites:
The WaveSense Presto System requires only 0.5 μL of blood to
perform a glucose test. For the best results, test glucose from
the tips of any finger. The palm (at the base of the thumb) and
