Refer to the following cautions whenever your test results are lower or
higher than what you expect.
①
Low glucose results
If your test result is lower than 2.2 mmol/L(40 mg/dL),
Lo will appear on the meter display screen. This
reading indicates severe hypoglycemia (low blood
glucose).
•
Lo Reading with Symptoms
If you have a Lo reading and have symptoms such as weakness,
sweating, nervousness, headache or confusion, then follow your
doctor’s recommendation to treat hypoglycemia.
•
Lo Reading without Symptoms
If you get a Lo reading, but have no symptoms of low blood glucose,
then retest with a new test strip on your fingers. If you still get a Lo
mmol/L
reading, follow your doctor’s recommendation to treat hypoglycemia.
