faculty village in anchorage ak 2How accurate is this test? The accuracy of this test depends on many factors including:

  • the quality of your meter
  • the quality of your test strips
    • Always use new test strips that are authorized for sale in the United States. The FDA has issued a safety communication warning about the risks of using previously owned test strips or test strips that are not authorized for sale in the United States
  • how well you perform the test. For example, you should wash and dry your hands before testing and closely follow the instructions for operating your meter.
  • your hematocrit (the amount of red blood cells in the blood). If you are severely dehydrated or anemic, your test results may be less accurate. Your health care provider can tell you if your hematocrit is low or high, and can discuss with you how it may affect your glucose testing.
  • interfering substances (Some substances, such as Vitamin C, Tylenol, and uric acid, may interfere with your glucose testing). Check the instructions for your meter and test strips to find out what substances may affect the testing accuracy.
  • altitude, temperature, and humidity (High altitude, low and high temperatures, and humidity can cause unpredictable effects on glucose results). Check the meter manual and test strip package insert for more information.
  • store and handle the meter and strips according to manufacturer''s web site. If you have an urgent problem, always contact your health care provider or a local emergency room for advice.

    faculty village in anchorage ak 2How do you choose a Glucose Meter? There are many different types of meters available for purchase that differ in several ways, including:

    • accuracy
    • amount of blood needed for each test
    • how easy it is to use
    • pain associated with using the product
    • testing speed
    • overall size
    • ability to store test results in memory
    • likelihood of interferences
    • ability to transmit data to a computer
    • cost of the meter
    • cost of the test strips used
    • doctor''s performance? There are three ways to make sure your meter works properly:

      1. Use liquid control solutions:
        • every time you open a new container of test strips
        • occasionally as you use the container of test strips
        • if you drop the meter
        • whenever you get unusual results
        To test a liquid control solution, you test a drop of these solutions just like you test a drop of your blood. The value you get should match the value written on the test strip vial label.
      2. Use electronic checks. Every time you turn on your meter, it does an electronic check. If it detects a problem it will give you an error code. Look in your meter''s manual, or contact your health care provider.
      3. Compare your meter with a blood glucose test performed in a laboratory. Take your meter with you to your next appointment with your health care provider. Ask your provider to watch your testing technique to make sure you are using the meter correctly. Ask your health care provider to have your blood tested with a laboratory method. If the values you obtain on your glucose meter match the laboratory values, then your meter is working well and you are using good technique.

      What should you do if your meter malfunctions? If your meter malfunctions, you should tell your health care provider and contact the company that made your meter and strips.

      Can you test blood glucose from sites other than your fingers? Some meters allow you to test blood from sites other than the fingertip. Examples of such alternative sampling sites are your palm, upper arm, forearm, thigh, or calf. Alternative site testing (AST) should not be performed at times when your blood glucose may be changing rapidly, as these alternative sampling sites may provide inaccurate results at those times. You should use only blood from your fingertip to test if any of the following applies:

      • you have just taken insulin
      • you think your blood sugar is low
      • you are not aware of symptoms when you become hypoglycemic
      • the results do not agree with the way you feel
      • you have just eaten
      • you have just exercised
      • you are ill
      • you are under stress

      Also, you should never use results from an alternative sampling site to calibrate a continuous glucose monitor (CGM), or in insulin dosing calculations.
