"E-4" Result
What It Means:
There may be a problem with the test strip.
What to Do:
Monitor your blood β-Ketone again with a
new test strip. If E-4 shows on the display
window again, contact your healthcare
professional immediately.
Important:
It is recommended that you repeat the blood β-Ketone
test with a new test strip when:
• HI appears in the display window.
• Your result is unusually high.
• You question your result.
• You obtain a 0.0 mmol/L blood β-Ketone result BUT your
blood glucose is higher than 16.7 mmol/L (300 mg/dL).
Important: A result that is incorrect may have a serious
medical outcome. Consult your healthcare professional
before changing your diabetes medication programme.

CHAPTER 6
Doing A Control
Solution Test
Why Do A Control Solution Test?
The control solution test tells you that your meter and test
strips are working correctly. A control solution test is similar
to when you monitor your blood
glucose or blood β-Ketone, except you
use an Optium or MediSense Control
Solution. You do not use a drop of
blood in a control solution test.
When Is Doing A Control Solution
Test Recommended?
• When you question your results.
• To make sure that your meter and
test strips are working properly.
