Glucose Meter

A glucose meter, also referred to as a glucometer, is a medical device for determining the approximate concentration of glucose in the blood. If you have diabetes, you'll likely need a blood glucose meter to measure and display the amount of sugar (glucose) in your blood. Exercise, food, medications, stress and other factors affect your blood glucose level. Using a blood glucose meter can help you better manage your diabetes by tracking any fluctuations in your blood glucose level. Many types of blood glucose meters are available, from basic models to more-advanced meters with multiple features and options.

• Blood glucose monitoring
• Diabetes management
• Home blood glucose testing

A glucose meter is a medical diagnostic device that measures the concentration of glucose in a blood sample. To use most blood glucose meters, you first insert a test strip into the device. Then with a special needle, you poke a clean fingertip to get a drop of blood. You carefully touch the test strip to the blood and wait for a blood glucose reading to appear on the screen. When used and stored properly, blood glucose meters are generally accurate in how they measure glucose.

A glucose meter measures blood glucose concentration through electrochemical or photometric reactions on a test strip and displays the result on a digital screen.

Frequency depends on the user's diabetes management needs. Generally, testing is recommended multiple times daily. Follow your doctor's advice on testing frequency.

Insert a test strip into the meter. Use a lancet to prick the fingertip to get a small drop of blood. Touch the blood to the designated area on the test strip. The glucose reading will appear on the screen within a few seconds. Read the device instruction manual before use.

Failure to test at scheduled times may result in unreliable results. It is recommended to follow a regular testing schedule.

When used properly, there are generally no side effects. Slight pain or discomfort may occur at the fingertip puncture site.

• Store test strips properly (away from moisture and heat)
• Calibrate the meter regularly
• Do not use expired test strips
• Wash and dry hands thoroughly before testing
• Check meter accuracy with control solution

• Do not use devices with optical or electronic defects
• Do not use expired test strips

Some medications such as acetaminophen, vitamin C, and dopamine may affect glucose test results. Inform your doctor about medications you are taking before testing.

Timing and type of food intake are important for accurate test results. Testing is recommended at specific times (e.g., before meals or 2 hours after meals).

Glucose meter use is safe during pregnancy. May be used regularly for monitoring gestational diabetes.

Glucose meter use is safe during lactation.

Pediatric patients should use meters with smaller lancets and smaller blood sample requirements. Consult a doctor before use in children.

Elderly patients should use meters with large displays and easy-to-use buttons.

Kidney or liver problems may affect glucose test results. Regular consultation with a doctor is recommended.

Overdose of insulin or medications may cause hypoglycemia. If abnormal results are obtained, consult a doctor immediately.

Store the test strip container and meter in a cool, dry place at 4°C-30°C. Keep away from direct sunlight and moisture. Refer to the test strip package insert for storage and operating conditions.
