Monitoring Blood
β-Ketone
"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 300 mg/dL (16.7 mmol/L).
IMPORTANT: A result that is incorrect may have a serious
medical outcome. Consult your healthcare professional
before changing your diabetes medication program.
