again with a new test strip. If
E-4 shows on the display

immediately.
Important: It is recommended
that you repeat the blood
ß-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

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.
