Warnings, Precautions, and Limitations
• Before testing, always make sure the meter is at operating temperature
between 50-104°F (10-40°C).
• If the meter has been exposed to extreme temperatures, move the
meter to an area within an operating range, and allow the meter and
test strips to warm up or cool down slowly (20 minutes) until the
temperature warning symbol goes away.
• Before testing, it is important to wash hands with soap and warm water.
Dry hands thoroughly. If you use alcohol wipes to cleanse fingers, make
sure the area is dry before lancing finger. Unwashed hands or residual
alcohol may lead to inaccurate readings.
• Never make significant changes to your diabetes control program or ignore
physical symptoms without consulting with your healthcare professional.
• Patients undergoing oxygen therapy may yield false results.
• Severe dehydration (excessive water loss) may cause false low results. If
you believe you are suffering from dehydration, consult your healthcare
professional right away.
• Extremes in hematocrit may affect test results. Hematocrit levels less than
30% may cause falsely high readings. Hematocrit levels greater than 55%
may cause falsely low readings.
