What Does This Mean For You

In meters, readings greater than 4.2 mmol/l, must have an accuracy of +-15 per cent for 99 per cent of readings.

However, lets translate this to real life with a couple of examples:

  • Your blood glucose meter reading of 10.0mmol/l really may range from 11.5 to 8.5mmol/l for 99 per cent of readings
  • Your blood glucose meter reading of 4.2mmol/l really may range from 4.8 to 3.6 mmol/l for 99 per cent of readings.
  • This also suggests that in the same blood drop if you used two different meters, readings may differ by up to 30 per cent. Many blood glucose meters have much better accuracy than this minimum standard, and therefore are accurate enough for you to base your decisions.

    Buying Guide For The Best Blood Glucose Meter

    So those were some of the suggestions for the best accurate glucose meters. Now the question is how to pick the right one for yourself? Well, to make it easy for you, here are some of the things that you need to take in consideration:

    One of the most important parts is the result delivery time. There are quite a lot of meters that offer you results in just a few seconds. But some of the best glucometer too take some time.

    What Is Considered Accurate For A Blood Glucose Monitor

    First of all, it is important to understand that in Canada, blood glucose monitors are licensed medical devices that are reviewed and approved by Health Canada. This means that before a blood glucose monitor can be used in Canada, the monitor and test strips must go through a rigorous review by Health Canada to ensure that they meet a number of requirements.

    When looking at accuracy of blood glucose monitors, the most important information a company must provide is a consensus error grid. What does that mean? Basically, the blood glucose result from the monitor is compared with a sample taken from the blood that is analyzed immediately at a lab. The values should be as close as possible and must be within a 15% range. If the blood glucose meter result is 15% higher or 15% lower than the blood sample, it is considered accurate. Obviously, the higher the number the bigger the difference could be. For example, if your glucose reading was 10 mmol/L, then the meter would be accurate if it was 8.5 to 11.5 mmol/L. However, when blood glucose is lower, the difference would be less. If your blood glucose reading was 4 mmol/L, then the monitor would be accurate if the result was between 3.4 and 4.6 mmol/L. This is the accuracy that all blood glucose monitors must demonstrate, in keeping with the International Organization for Standardization, an international body that promotes worldwide standards for a number of devices, products and materials.

    Inclusion And Exclusion Criteria

    Inclusion criteria for the current systematic review were as follows: studies conducted in critically ill adult patients, studies in which the accuracy of glucose monitoring was assessed by using ABGs and/or glucose meters, studies in which Glu-lab values were used as reference values, and articles presenting an appropriate summary of statistics. We excluded nonhuman studies, non-English-language articles, and pediatric studies.

    Testing Technique And Site

    Meter Accuracy: Checking Your Blood Sugar With Confidence

    Make sure youre following the directions of your meter. Traditionally, fingertips are the primary place to test your blood sugar. Alternative testing sites such as on the palm, upper arm, forearm, thigh, and calf are used, typically in clinical settings, instead of fingers due to the many nerve endings on fingers, including the pain from testing and the resulting calloused fingers. But, it isnt advised to use an alternate site unless you have a device thats designed for it. However, using an alternate site may not always produce accurate results, especially if your blood sugar is rising or falling fast. Research shows that glucose readings differ depending on if you get your blood sample from the capillaries in your fingers or another part of your body.

    Another note about the technique make sure you have enough blood in your test strip. Having too little blood will cause an error or false reading. You can adjust the settings on your lancet to make sure youre drawing enough blood. Finally, make sure youre fully inserting the test strip into your meter.

    Compare With Recent Lab Results

    If you have noticed inconsistent or irregular results, be sure to bring your glucose monitor with you to your next appointment . Have your doctor take a sample and run their own tests, then immediately test your blood sugar on the spot to compare it to their well-controlled results. Physicians say that results +/- 15% of a lab reading are considered accurate.

    How You Prepare Before Pricking Your Finger

    Especially among children , studies have found people with diabetes rarely wash their hands prior to glucose testing. Even if you werent recently touching food something that could easily lead to an inaccurate reading other things on your hands could potentially affect the accuracy. Hand lotion, ink from a newspaper, hair product, make-up, sweat, and even water after washing your hands if you dont dry them thoroughly.

    Proper blood sugar checking technique for greatest accuracy:

    • Wash your hands or use an alcohol swab on that finger
    • Be sure your test strips are within their expiration date
    • Use control solution to verify your strips and meter are reading within range
    • Avoiding touching the end of the strip where blood will be applied
    • Be sure to apply enough blood to completely fill the test strip
    • Avoid testing in extremely hot or cold temperatures
    • Be sure to completely close the test strip container to prevent humidity and other environmental factors from negatively impacting all of your strips

    In real life diabetes management with type 1 diabetes or type 2 diabetes, its not always possible to control all of these variables. But keep in mind that if youre checking your blood sugar at the top of a mountain in New Mexico and your entire diabetes kit feels hot to the touch, your results may not be as accurate. The same goes for checking in the middle of a ski trip to Vermont when its 10 degrees outside!

But in some cases, it might require about 0.4 to 0.5 microliters of blood. And the thing with the blood glucose meters that requires more blood may force you to run a test all over again. Because it did not extract the needed blood volume in the first attempt.

    How Does Your Glucose Meter Work

    Weve come a long way from the days when urine strips only displayed a result when your glucose levels were high enough to spill over into your urine. But how accurate are todays blood glucose meters?

    When you place your blood on a strip, the glucose in that sample reacts with the chemicals in the strip setting up a small electrical current, which the meter reads. The more glucose that is in the sample the higher the current and the higher the reading.

    When you consider the delicate components in the strip, such as the size of the strip and blood sample and the size of the meter, it is a wonder of technology that readings can be as accurate as they are.

    Most Common Factors That Affect Glucose Meter Accuracy

    People with diabetes are familiar with the feeling that comes if they skip lunch . But thats not the only thing affecting blood glucose readings. Because our glucose level is affected by many other factors, such as the multiple components that make up your blood,blood glucose meter technology has improved to lessen the impact of these. Even so, these are the most common reasons we see inaccuracies in readings:

    General Accuracy And Variance Criteria

    Blood glucose test results are used by people with diabetes to make critical decisions about their treatment therefore, it is important that the results are accurate so that nutritional and drug dosing errors are better avoided, explains the FDAs guidance document.

    For any glucose meter seeking FDA-approval, studies should demonstrate that 95 percent of all blood sugar level results are within 15 to 20 percent of the blood lab value.

    The acceptable 5 percent of results that are greater than a 20 percent variance should be explained in detail by the manufacturer to justify why the errors occurred. Reasons might include an extremely large number of tests or patients using the device incorrectly by not washing their hands before testing, etc.

    Factors Associated With Error Of Blood

    In six studies, risk factors for inaccuracy of glucose measurements were determined . Patient’s factors , except for age, were not significantly related to inaccuracy. Young age was significantly associated with increased risk of nonagreement for Gluco-C in one study . No laboratory data were associated with inaccuracy.

    Table 5 Risk factors for inaccuracy of glucose monitoring

    For Gluco-C, low perfusion index , use of a vasopressor and presence of edema were significantly associated with inaccuracy. For Gluco-A, use of a vasopressor , low peripheral perfusion, and low mean arterial pressure were associated with inaccuracy.

    Smart Accurate Mg/dL Blood Glucose Meter With Bottled Stripes And ...

    Our diabetes educator helps you understand your blood glucose meter.

    My patients frequently come to me with questions concerning their blood glucose testing equipment. A commonly asked question is Why do my testing results vary meter to meter? The answer simplified is that meters are tested for accuracy and must adhere to Self-Testing Blood Glucose Monitoring System ISO standard and US guidance, and can only vary by 15 percent compared to reference method. The variation allowance confused a lot of patients. This can be especially alarming when using a new product that doesnt seem to match up to a blood glucose meter you have been using.

    The ISO, International Standards Organization, has guidelines that meter companies must meet and the FDA in the US as well. Currently, all measured blood glucose meter values must be within 15 percent of the true lab value of blood glucose 95 percent of the time and within 20 percent of the lab value 99 percent of the time

    Although this can be confusing, a blood glucose value that is a lab value of 100mg/dl could conceivably show up on a meter as 80-120mg/dl and still be considered accurate.

    Fortunately, Dario has undergone considerable testing and meets and/or exceeds ISO standards by being within 20 percent 99% of the time.

    So, dont forget: Choose one meter to test to ensure regularity and reliability and to reduce confusion. Choose Dario.
