than 600 mg/dL and indicates severe

If “HI” is displayed again on retesting, please contact your
healthcare professional immediately.

than 20 mg/dL and indicates severe
hypoglycemia (very low glucose
levels). If “Lo” is displayed again
on retesting, please contact your
healthcare professional immediately.

on, symbol also appears.
