When your blood glucose test result
is above 240 mg/dL or reads h1,
"Ç" will appear on
the meter display. This message
does not mean that the system
detected ketones but that testing
with a ketone test strip may be
advisable. Consult your health care
professional about when and how
Example
to test for ketones.
NOTE: Do Not use a ketone strip with the OneTouch
Ultra Meter.
