5. Check if the result is in range
Each vial of test strips has both
OneTouch Verio® Level 3 (Mid)
and OneTouch Verio® Level 4
(High) Control Solution ranges
printed on its label.
Compare the result displayed
on the meter to either the
OneTouch Verio® Level 3 (Mid)
and OneTouch Verio® Level 4
(High) Control Solution range
printed on the test strip vial,
depending on the type of
control solution you used.
Out-of-range results may be due to:
• Not following the instructions detailed on pages 49–53.
• Control solution is contaminated, expired, or past its
discard date.
• Test strip or test strip vial is damaged, expired, or past
its discard date.
• Meter, test strips and/or control solution were not all at
the same temperature when the control solution test
was performed.
• A problem with the meter.
• Dirt or contamination in the small well on the top of
the control solution cap (see Step 2).
