Accuracy In Blood Glucose Monitoring

How Accurate are Blood Sugar Monitors?

In 2013, the International Organisation for Standardization published revised quality standards for blood glucose meters in order to improve accuracy and consistency of results. Following the transition period, the UK adopted this standard as EN ISO 15197:2015.

ISO 15197 has four significant improvements on the previous standard .

  • Increased accuracy for glucose meter systems, in particular for glucose values equal to or greater than 5.5 mmol/L
  • Manufacturers of glucose meter systems must ensure their technology enables accuracy to improve from ±20% to ±15%
  • The current standard covers 99% of results, as opposed to 95% under the old one
  • For the first time, the standard provides formal acceptance criteria for accuracy as regards testing by patients as well as assessment of potential interfering substances

What does ±15% mean in practice? For example, when a laboratory test would say 6.0 mmol/L, a blood glucose meter that meets the ISO standard could show anywhere between 5.1 mmol/L and 7.0 mmols/L and still be called accurate.

Choosing A More Accurate Glucose Meter

Accurate blood glucose measurement is a vital tool to manage diabetes and provide critical guidance for your doctor. This means its crucial to understand the factors that can affect your blood glucose levels and your blood glucose meter.

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.

  • Although only current-generation BGMS were tested, more than 20% did not meet ISO 15197 accuracy criteria with their tested reagent system lot.

  • Considerable variation in measurement accuracy was found even among BGMS that meet these criteria.

  • Regular post-market surveillance of all available BGMS is necessary to allow patients with diabetes and healthcare professionals selecting a BGMS that is best possible for diabetes therapy.

How might these results change the focus of research or clinical practice?

  • These results should be taken into account by patients and healthcare professionals when choosing a BGMS for therapy or when making therapy decisions.

While insurance and Medicare do cover CGMs, these monitors are more expensive overall. Depending on your insurance, they may offer coverage for one type of CGM but not another. Its important to check these details with your provider ahead of time.

If you dont have insurance, you can check with your doctor or pharmacist for discounts on your CGM and accessories. Its also possible to get coupons directly from the manufacturer to help offset the costs.

How To Choose An Accurate Meter

Independent testing, like the study done by the Diabetes Technology Society, is helpful to compare the performance of top commercially available glucose meters. This study tested meters and test strips which were independently purchased from stores across the country, and representative of what a consumer would purchase.

After testing the products over 300 times at three different clinical sites, the results showed that over 66% of the top meters on the market today didnt pass the rigorous study.

A surprising number of name brand meters did not pass all studies. Check the list below to see the 12 meters that failed one or more study.

The following devices passed the test and received the Diabetes Technology Societys Seal of Approval:

CGMs can help people with diabetes monitor and maintain their blood glucose levels. While they do not involve finger pricking, they may be useful for calibrating the device.

Earlobe, breath, and other noninvasive devices may be beneficial for monitoring blood glucose levels, especially in children with the same condition and those who have cystic fibrosis. However, they are not FDA-approved, and some may need further testing to determine their safety and accuracy.

How Accurate Is The Average Fda

When it comes to FDA-approved glucose meters, a meter must meet certain blood glucose meter accuracy standards similar to those set by the International Organization for Standardization , but its important to know that accuracy does not mean an exact measurement.

Every glucose meter and blood glucose monitoring system available for sale in the United States today is approved by the Food and Drug Administration and is required to be within 15 percent of lab value glucose readings 95 percent of the time, and within 20 percent of âlab results 99 percent of the time .

Diathrives meter is within 15 percent of lab value 99 percent of the time!

Take a look at how the blood glucose value on your glucose meter is actually giving you a number within a range rather than an exact number.

To assess the variance in any blood sugar reading of your own, simply multiply the number on your glucose meter by 0.15. Then subtract and add that result to the number on your meter to determine the full range of your actual glucose level.


211 mg/dL x .15 32

211 â 32 = 179 mg/dL

211 + 32 = 243 mg/dL

Could checking again with the same meter help narrow the results to give more accurate readings? Maybe. But realistically, using two or three strips every time you check your blood sugar is not a practical long-term plan. If youre looking at an extremely high number, checking again might provide a bit more assurance in your calculated correction dose of insulin.

How Are These Tests Different

Meter Accuracy: Checking Your Blood Sugar With Confidence

Personal meters measure your blood glucose using a sample from your fingertip , and then analyze the whole blood, including red blood cells and all.

In a lab test performed by clinical staff, the sample is typically drawn from a vein in your arm and processed to remove red blood cells, so only the plasma is tested.

Virtually all home glucose meters factor in the difference of using a whole blood sample while providing a test result that is considered plasma equivalent.

For the other BGMs, > 2% of readings were > 20% from the reference value, with the exception of LifeScan OneTouch Verio, which had 1.3% of readings > 20% from the reference value.
