Symptoms of Low or High Blood Glucose

WARNING
The meter is designed to provide a numerical value for blood glucose in the range of 20–600 mg/dL. If
you receive a numerical value below 20 mg/dL or above 600 mg/dL and it does not match how you
feel, contact the ACCU-CHEK Customer Care Service Center toll-free at 1-800-858-8072.
Being aware of the symptoms of low or high blood glucose can help you understand your test results and
decide what to do if they seem unusual.
Low blood glucose (hypoglycemia): Symptoms of hypoglycemia may include, but are not limited to, anxiety,
shakiness, sweating, headache, increased hunger, dizziness, pale skin color, sudden change in mood or
irritability, fatigue, di culty concentrating, clumsiness, palpitations, and/or confusion.
High blood glucose (hyperglycemia): Symptoms of hyperglycemia may include, but are not limited to,
increased thirst, frequent urination, blurred vision, drowsiness, and/or unexplained weight loss.
If you are experiencing any of these symptoms, or other unusual symptoms, test your blood glucose from
the fingertip. If your blood glucose result is displayed as LO or HI, follow your healthcare professional's
instructions or contact your healthcare professional immediately. If your blood glucose result does not match
how you feel, follow the steps under Chapter 4, Unusual Blood Glucose Results.

Comparing Your Meter Result to a Laboratory Result

A common question is how the blood glucose results on the meter compare to the laboratory results. Your
blood glucose can change quickly, especially after eating, taking medication, or physical activity. If you test
yourself in the morning, then go to your healthcare professional's o ce for a blood glucose test, your test
results will probably not match, even if you are fasting. This is typically not a problem with the meter, it just
means that time has elapsed and your blood glucose level has changed.
Although you always apply fresh capillary whole blood to the test strip, the system has been calibrated to
deliver plasma-like values for easier comparison to laboratory results.
If you want to compare your meter result to the laboratory result, you must be fasting. Take the meter to
your healthcare professional's o ce and test yourself by fingerstick within 5 minutes of having blood drawn
from your arm by a healthcare professional. Keep in mind that the laboratory uses di erent technology than
the meter and that blood glucose meters for self-testing generally read somewhat lower than the laboratory
result.
