LO and HI Readings
Important: Low or high blood glucose readings can indicate a potentially
serious medical condition. The FreeStyle® Lite Meter displays results from
20 to 500 mg/dL.
If your test result is lower than 20 mg/dL, LO will appear on the meter
display screen. This reading indicates severe hypoglycemia (low blood
glucose).
LO Reading
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
reading, follow your doctor's recommendation to treat hypoglycemia.
If your test is above 500 mg/dL, HI will appear on the display screen.
This indicates severe hyperglycemia (high blood glucose).
HI Reading
HI Reading without Symptoms
If you get a HI reading, but have no symptoms of high blood glucose,
then retest with a new test strip. If you still get a HI reading, follow
your doctor's recommendation to treat hyperglycemia.
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.
HI Reading with Symptoms
If you feel symptoms such as fatigue, thirst, excess
urination, or blurry vision, then follow your
doctor's recommendation to treat hyperglycemia.
