If the SG readings do not match symptoms, use a BG meter reading to confirm the SG value. If SG
readings continue to be different than symptoms, consult the healthcare professional about how to
use SG readings to help manage diabetes.
When to use BG meter readings
In the following conditions, use the BG meter readings to make treatment decisions.
• The medication taken contains paracetamol or acetaminophen.
Wait to use the SG reading to make treatment decisions until no longer taking medication.
Medication that contains paracetamol or acetaminophen used to reduce fevers or treat cold and
flu symptoms, can falsely raise SG readings.
• The most recent SG reading is unavailable.
If a new sensor is inserted or the Sensor updating message is displayed the SG reading will be
unavailable. Check the BG value with a BG meter reading, and use the BG reading to make
treatment decisions until sensor readings are available.
• Symptoms do not match the SG value.
Check the BG value with a BG meter reading before using the SG value to make treatment
decisions.
Enter the BG meter reading into the app immediately after checking BG. Review the BG meter
instructions for guidance on how to check the BG.
CAUTION: Only use blood from fingertips to check BG levels. Do not use any other part
of the body to obtain blood to test BG.
– Always make sure hands are clean before testing BG.
– Avoid use of an old BG reading or reuse of BG readings from previous calibrations.
– If for some reason calibration is unsuccessful, wait at least 15 minutes before attempting
another calibration.
Note: The Guardian app contains a feature which provides alerts prior to SG levels reaching a set
high or low limit. SG readings can vary from actual BG readings, therefore there may be situations
when alerts are displayed and BG levels have not reached the set high or low limit. Consult the
healthcare professional for actions and adjustments to alerts. There may also be situations when
BG levels have reached the set high or low limit without any alerts displayed on the Guardian app.
If there are symptoms of high or low BG levels, check the BG value immediately. Consult the
healthcare professional for actions and adjustments for high or low BG levels.
