Warnings/Limitations
•
Review all product information before use .
•
Physiologic differences between the interstitial fluid and capillary blood
may result in differences in glucose readings . Differences in glucose
readings between interstitial fluid and capillary blood may be observed
during times of rapid change in blood glucose, such as after eating,
dosing insulin, or exercising .
•
Severe dehydration and excessive water loss may cause inaccurate
results .
•
Do not reuse Sensors . The Sensor and Sensor Applicator are designed
for single use . Reuse may result in no glucose readings and infection .
Not suitable for re-sterilization . Further exposure to irradiation may
cause inaccurate results .
•
Interfering Substances: Taking ascorbic acid (vitamin C) while wearing
the Sensor may falsely raise Sensor glucose readings . Taking salicylic
acid (used in some pain relievers such as aspirin and some skin care
products) may slightly lower Sensor glucose readings . The level of
inaccuracy depends on the amount of the interfering substance active
in the body . Test results did not indicate interference for methyldopa
(used in some drugs to treat high blood pressure) or tolbutamide
(infrequently used in some drugs to treat diabetes in the US) at
maximum circulating levels . However, concentrations of potential
interferents in interstitial fluid are unknown compared to circulating
blood .
