Which glucose monitor is the most accurate

I have been using the Advocate Redi Code meter for years. It is a reliable way of measuring your blood glucose levels on a daily basis. This compact machine provides the readings in a clear and audible voice and the numbers are bold and easily read. I highly recommend it.” – From Advocate’s site. 

Advocate Redi-Code+ Speaking Blood Glucose Meter is a reliable option for those who are looking for both safe and accurate monitoring of blood glucose levels. One of its defining features is that it has the ability to speak, which can be beneficial for users who have sight impairments. The meter can speak in both English and Spanish. 

Some other great features of Advocate Redi-Code+ include fast results in five seconds and six daily alarm reminders to help ensure that users are remembering to check their blood sugar levels when appropriate. Users will also appreciate the big-screen display which makes results clear and easy to read, as well as pre and post-meal testing.

Freestyle Libre

Which glucose monitor is the most accurate

When it comes to glucose meters, not all of them need to involve sticking your finger to draw blood. This isn’t a big deal for many folks, as they’ve simply gotten quickly used to it. However, for some people with diabetes, the idea of sticking your finger multiple times a day is rather dreadful. For this reason, continuous blood glucose monitoring systems like Freestyle Libre were made.

Freestyle Libre allows the user to insert a thin sensor under their skin (not nearly as painful as it sounds), allowing you to wear it all day. Not only does this provide the added benefit of not needing to prick your finger throughout the day, but it also monitors all day long so that you can gain a better understanding of your glucose levels as they fluctuate throughout the day. However, you do have to manually scan the sensor to actually see a reading.

Dexcom G6

Which glucose monitor is the most accurate

While Freestyle Libre involves manually scanning the sensor to get a glucose reading, the Dexcom G6 uses a similar sensor but automatically keeps tabs on your glucose levels throughout the day. While users have to once again be comfortable with inserting the sensor under their skin, they can gain valuable insight into how their dietary choices and activity levels impact glucose.

In addition to automatic glucose monitoring, the Dexcom G6 is also smartphone and Apple Watch compatible. Therefore, users can either have their reading sent wirelessly to the Dexcom handheld device, or they can pair with their smartphone or Apple Watch through Dexcom’s app. In a world that is becoming more and more technologically advanced, compatibility is something everyone wants in their devices—from laptops to speakers to glucose meters.

ReliOn Prime

Which glucose monitor is the most accurate

If you’re looking for a cheaper glucose meter solution that still gets the job done, ReliOn Prime is one of the most affordable options on the market today. For less than $18, you can get the meter along with 50 strips. Keep in mind, the meter and the strips must be bought separately.

The ReliOn can store up to 250 blood sugar readings, which is a surprisingly high amount for a meter at this price point. However, the meter does not have a smartphone or app pairing capabilities. Of course, that comes as no surprise, but it is important to note in case you are curious about understanding your glucose levels over the long term. For this reason, the meter makes for a great option if you are traveling. 

Care Touch Diabetes Testing Kit

Which glucose monitor is the most accurate

Care Touch offers users a fast result through an inexpensive meter. Also, its test strips are reasonably priced. Although it is far from the most technologically advanced meter you’ll find on the market, it does offer data annotation. For example, you can add details like “post-meal” or “post-workout.” By doing so, you can get a better understanding of how your day-to-day activities affect your glucose levels.

The meter is also extremely easy to use, and you can purchase a complete kit, which includes the monitor along with 100 test strips, a lancing device, 30 lancets, and a carrying bag plus a battery.

Accu Chek Aviva Plus Meter

Easy to handle and extremely accurate, the Accu Chek Aviva Plus is an exceptional glucose meter. In fact, the Accu Chek Aviva Plus Meter is so spot-on with its levels, it has won awards because of its accuracy. The meter also allows you to download test results to your computer. This feature is great for those who want to keep track of their blood sugar levels over a long period of time and identify trends. While this meter is a little pricey, it is a great option for those who need a new meter that produces consistent results day in and day out.

Most Accurate Blood Glucose Meters

Glucose meter accuracy has long been a hot topic of discussion. In a previous blog, “Is my meter accurate,” we discuss some of the technical details of meter accuracy. However, to us with diabetes, the accuracy of our meter becomes very personal.

According to the Diabetes Technology Society surveillance study in 2017, only 6 of the 18 meters passed the accepted standard of accuracy. Industry focus on accuracy resulted in the FDA issuing new guidance in October 2016. Meters cleared by the FDA before this guidance were not required to meet this guidance to continue to be sold. Even meters released after 2016 were allowed to bypass the requirement if they were substantially the same as previously cleared meters. New meters released after 2016 are required to meet the tighter 2016 guidance. 

The Importance of Meter Accuracy

Accurate readings of your blood glucose are obviously very important because you need to know how much insulin you need or if you need to eat a snack before your blood sugar gets too low or too high. But there are other reasons why meter accuracy is so important.

  • You gather reliable data that you can trust to manage your diabetes appropriately and compare past and current numbers to make adjustments to your care plan.
  • You can better anticipate lab results when you go for your regular checkups and blood work.
  • Know what foods affect your blood sugar and how you can combat any adverse changes in glucose levels
  • Accurately dose your insulin or other medications based on accurate test results.

Factors That Can Affect Accuracy in a Glucose Meter

Even the most accurate glucose meter in the world needs to follow specific rules and protocols to ensure near 100% accuracy. Many things can affect how well your glucose test comes out. The key is to follow the blood glucose meter instructions, but also consider the following:

Testing Technique

The way you test can severely affect the results. This means you should always follow the instructions and avoid using alternate sites on the body (outside of your finger) unless otherwise directed, and always make sure you have enough blood on the test strip to get a reading. Using the wrong technique consistently could mean months of inaccurate blood glucose levels, and thus poor diabetes management, which could be very dangerous.

Clean Testing Site

It can be really easy to want to get lazy because you constantly have to check your blood sugar levels, but taking the time to clean and sterilize the testing site and to wash your hands can be the difference between a correct and incorrect test result. Any amount of dirt or grease on your hands or near the testing site can affect the outcome.

Temperature and Environment

Your meter needs to be stored in proper conditions—super high or super low temperatures as well as higher altitudes can diminish the glucose meter accuracy.

Glucose Meter Quality

Yes, the quality of the meter matters! When it comes to managing your diabetes, don’t go cheap. Your glucose meter should also meet all of the standards we mentioned above.

Testing Strips Quality

This is an important one to follow: always purchase testing strips that are compatible with your glucose meter, are not expired, and are of a quality brand and manufacturer. Sometimes you may think buying bulk testing strips will save you money in the long run, but often they can expire or be of poor quality, and in the end, you’ll pay the price with your health.

Calibrating the Meter

Follow your instructions to set up and calibrate your meter when you get it. Calibration ensures the readings are accurate based on your environment and your specific needs.

Altering Medications

If you take other medications or supplements, always check with your doctor to ensure they won’t affect your accurate results. Oddly enough, acetaminophen and ascorbic acid (vitamin C) can show falsified results (often lower than normal).

The Most Accurate Meters

Because accuracy is so important, we look at meters that have proven accuracy in industry data. These blood glucose meters have been tested against the industry standards via the surveillance program. Based on those results, here is our list of the most accurate meters available on the market today.

Bayer Contour Next—100%

  • The Diabetes Technology Society Surveillance Program results showed that 100% of the Contour Next results were within the required 15% window.

Pops Rebel—100%

  • Data presented at the Diabetes Technology Society by Dr. Baily of AMCR demonstrated that 100% of the Pops Rebel results were within the required 15% window.

Roche Accu-Chek Viva Plus—98%

  • The Diabetes Technology Society Surveillance Program results showed that 98% of the Contour Next results were within the required 15% window.

Walmart ReliOn—97%

  • The Diabetes Technology Society Surveillance Program results showed that 97% of the Contour Next results were within the required 15% window.

CVS Advanced—97%

  • The Diabetes Technology Society Surveillance Program results showed that 97% of the Contour Next results were within the required 15% window.

FreeStyle Lite—96%

  • The Diabetes Technology Society Surveillance Program results showed that 96% of the Contour Next results were within the required 15% window.

Roche Accu-chek SmartView—95%

  • The Diabetes Technology Society Surveillance Program results showed that 95% of the Contour Next results were within the required 15% window.

The Importance of a Good Blood Glucose Meter

It’s important to make sure that you use a good blood glucose or blood sugar meter. Roughly 1 in 10 people throughout the US will struggle with diabetes. That number is likely to rise according to experts. With a high-quality blood sugar metering system, you’ll be able to help them improve their quality of life and overall health.

Which continuous glucose monitor is the most accurate?

A quick look at the best home glucose monitors and meters.
Best overall for new users: Care Touch Blood Glucose Monitoring System..
Best for blood-free readings: FreeStyle Libre..
Most accurate continuous glucose monitor (CGM): Dexcom G6..
Longest lasting CGM sensor: Eversense..

Which is better Accu

The Accu-chek Advantage is capable of estimating both capillary and venous blood glucose to the same level of accuracy. The Onetouch Horizon and Sensocard are however incapable of efficiently estimating venous blood glucose.

How do I know if my glucose meter is accurate?

Check your blood sugar level with your meter at the same time that blood is drawn for lab tests, being sure to use a fingerstick sample, not blood from the blood draw. Then compare your meter's reading with the lab results. Results that are within 15% of the lab reading are considered accurate.

Which is more accurate FreeStyle Libre or glucometer?

The gold standard for accuracy is a blood draw measurement and both finger sticks and CGMs have error margins (MARD) to that standard. Finger sticks tend to be in the range of 5-10% MARD, while the Libre has a MARD of about 9.7% over 14 days, and the Dexcom G6 has a MARD of 9% over 10 days.
