iHealth Align - Manual (Page 14)

Food, medication, illness, stress, and exercise can affect blood glucose levels. Capillary blood
from the fingertips reflects these changes faster than capillary blood from other sites. AST should
be used only during steady-state times when blood glucose levels are not changing rapidly.
You may perform Alternate Site Testing in the following instances:
• In a pre-meal or fasting state (two hours or more after the last meal).
• Two hours or more after taking insulin.
• Two hours or more after exercising.
You should NOT perform AST if:
IMPORTANT INFORMATION ABOUT CONTROL SOLUTION TESTS
The control solution contains a known amount of glucose that reacts with test strips and is used
to check that your meter and test strips are working together properly. The result of the control
solution test should be within the range printed on the test strip vial label.
Materials needed to perform a control solution test:
• iHealth Align Gluco-Monitoring System (BG1)
• iHealth Blood Glucose Test Strip（AGS1000I）
• iHealth Control Solution (Level I, Level II, or Level III)
Perform a control solution test when:
• First receiving or purchasing the meter.
• Checking the meter and test strips (which should be done at least once a week).
• Using a new vial of test strips.
• You suspect the meter and/or test strips are not working properly.
• Your blood glucose test results are not consistent with your expectations, or you think the
results are not accurate.
• Practicing the testing process.
• After the test strips are exposed to extreme conditions.
• The meter has been dropped or damaged.
Out-of-Range Results
Results falling outside the specified range may be caused by:
• Error in performing the test.
• Expired or contaminated control solution.
• Expired or contaminated test strip.
• Meter malfunction.
If you continue to get control solution test results that fall outside of the range printed on the vial,
the meter may not be working properly. Discontinue use and call iHealth Labs Customer Service
at 1-855-816-7705 for assistance.
To purchase additional control solution, call iHealth Labs Customer Service.
NOTE:
• Do not use expired control solution.
• The control solution range printed on the test strip vial is for control solution use only. It is not a
recommended range for your blood glucose level.
