If this confirms how you feel, contact your
healthcare professional immediately. If it does not
confirm how you feel, repeat the test and see
Chapter 2, Testing Your Blood Glucose. If this still
does not confirm how you feel, perform a control
test with your control solution and a new test strip.
If the control result is within the acceptable range,
review the proper testing procedure and repeat your
blood glucose test with a new test strip. If the E-53
error still appears for your blood glucose test, your
blood glucose test result may be extremely high and
above the system’s reading range.
Contact your
healthcare professional immediately.
If the
control test result is not within the acceptable
range, see Chapter 3, Control Testing.
