Your blood glucose may be extremely high or a meter or a test strip error has occurred.
• If your test result matches how you feel, contact your healthcare professional immediately.
• If your test result does not match how you feel, repeat the blood glucose test. See
Chapter 4, Unusual Blood Glucose Results.
Not enough blood or control solution was drawn into the test strip for measurement or was
applied after the test had started. Discard the test strip and repeat the test.
The code key is from an expired lot of test strips. Make sure the code key number matches
the code number on the test strip container. Make sure the time and date in the meter are
correct.

Maintenance and Troubleshooting

• If the E‑3 code still appears for your blood glucose test, your blood glucose result
may be extremely high and above the system's reading range. Contact your
healthcare professional immediately.
• If the second test result does not match how you feel, perform a control test with the
control solution and a new test strip.
• If the control result is within the acceptable range, review the proper testing
procedure and repeat the blood glucose test with a new test strip.
• If the control result is not within the acceptable range, see Chapter 2,
Understanding Out‑of‑Range Control Results.
