Basic Blood Glucose Meters

At its simplest, a glucometer is a hand-held instrument with a digital screen that’s used with disposable test strips treated with chemicals that react to glucose. Some glucose meters come with a lancing devicean instrument that uses a spring-loaded needle to create a tiny puncture in the skin, from which a blood sample is obtained. Lancing devices and lancets can be purchased separately, however, and the size of the lancet can be adjusted depending on personal comfort.

To get a blood glucose measurement, a person draws a blood sample and carefully touches it to a test strip that’s been inserted into the device. The test strip absorbs the blood, and then an electronic circuit detects the glucose on the strip, displaying it as a number on the screen, usually within seconds.

Most meters run on batteries and have at least a minimal amount of memory for storing results. With very few exceptions, most also have the capability to download and store results to a computer.

But there are other features to consider, such as:

Minimed 670g System An Advanced Blood Sugar Monitor System

The developer of this MiniMed 670G System is again Medtronic MiniMed, Inc.

What makes this CGM system so special is that its the first hybrid closed-loop system approved by the FDA.

The hybrid closed-loop system possibly frees the individual from some of the everyday chores required for the stability of the blood glucose levels.

Or it might help the user in sleeping through nighttime by cutting the need for waking and testing glucose or taking medicine.

Nonetheless, consult your healthcare provider to know if this system is appropriate for you or not.

Noticeably, this CGM system is capable of monitoring glucose and adjusting the delivery of basal or long-acting insulin automatically on the basis of glucose reading of the user.

Besides, it comprises a continuous glucose monitor for measurement of the glucose levels of the user for more than 7 days. Additionally, an insulin pump is also there delivering insulin to the user as well as a glucose meter for the calibration of the CGM.

More interestingly, this CGM system is capable of decreasing or stopping the delivery of insulin after detecting a fall in glucose levels of the user. Or rise in the glucose levels without his/her input.

Substances On The Skin

Substances that you had touched or put on your skin may end up contaminating your blood sample causing the results to show an error.

Since most glucometers utilize a very small or micro-sized sample of blood, not washing your hands or touching anything that contains sugar could affect your reading.

Also, if you have washed your hands just before the testing and havent dried them completely, the water droplets left on your fingers may create a diluting effect on the blood sample causing errors in the reading.

You can avoid these errors by washing your hands and drying them thoroughly before every test.

How Accurate Are Blood Glucose Meters

If you have Type 1 or Type 2 diabetes, then you know how important it is to check your blood sugar, whether thats with a CGM or the manual BGM . And when you are on one end of the spectrum, or just not convinced by your CGM number, you test with a blood glucose meter, right? But what if your BGM were inaccurate as well? Just how accurate is the quintessential diabetes management tool?

An independent study by the Diabetes Technology Society of 18 popular FDA-approved blood glucose monitoring systems released last month found that only six tested meters recorded BGLs as consistently and dependably as laboratory tests.

The six highest-functioning monitors reported results within 15 percent of laboratory tests taken for comparison 95 percent of the time. The other 12 meters were only on the mark between 71 and 92 percent of the time. While the deviation on the meters was sometimes minor, minor mistakes can eventually lead to big complications.

The study used BGMs bought in retail locations and tested 1,035 people in three different laboratory locations. It was conducted by a team of researchers led by David C. Klonoff, MD, of the Diabetes Research Institute at San Mateo, Calif.-based Mills-Peninsula Medical Center and funded by Abbott Laboratories.

The study was not isolated to people with T1D. Among those who participated in testing the BGMs, 370 people had T1D, while the others had T2D, pre-diabetes, or did not have diabetes at all.

High blood sugar is an ever-increasing global health problem caused due to unhealthy lifestyle. To keep it in check, glucose meters are something that we usually use. Blood glucose or blood sugar is typically measured in milligrams per deciliter, or you can say mg/dL. Doctors usually use the best glucose meter for diabetes and perform two blood sugar tests basically on two separate occasions.

And two readings of the 126 mg/dL or greater confirm the presence of the chronic, incurable disease in your body. Also, a fasting blood sugar level between 100 to 125 mg/dL is a clear sign of prediabetes. And in healthy individuals, sugar is something that offers vital energy to the cells.

But if you have diabetes, then elevated blood sugar can act as slow poison. And high blood sugar makes it difficult for your body to function properly.

However, in short, if you have diabetes and you are concerned about your blood sugar levels, then a blood glucose meter will allow you to check blood sugar levels easily. But when it comes to purchasing one, there are quite a lot of options that are available out there.

And to help you out, I am going to share a list of some of the best blood glucose meters for you. So lets just go ahead and have a look at them:

Testing Technique And Site

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.

I ve summarized the list of best glucose meters for all the lazy diabetics out there like me. However, I recommend you to read the full article and sort it out by yourselves.

What’s Inside

Types Of Glucose Meters

There are two types of glucose metersstandard and continuous. Our ranking only analyzed standard glucose meters, which can be a good fit for people who dont require frequent testing or insulin injections. These types of meters measure current blood glucose by using a finger stick blood sample placed on a test strip and inserted into the device.

Meanwhile, continuous glucose monitors work by wearing a sensor placed under the skin that measures glucose levels in real time. People who might benefit from a CGM include those with type 1 diabetes, people who require tight blood sugar control or dont experience warning signs of low blood glucose and those who have frequent high or low levels. CGMs dont require as many finger sticks, and as of July 2021, Medicare permanently eliminated the requirement of a four-time daily finger stick to qualify for CGM coverage.

Talk to your doctor about which type of glucose meter is best for you and your needs.

Amount Of Blood In Your Test Strip

Its possible to have too much or not enough blood in the test strip sample area, which can lead to inaccurate results or an error reading.

Accuracy Tip: Your meter should state the required blood sample size, like 0.5 microliters, so you have an understanding of how much blood is needed for testing. Avoid squeezing directly around the lanced area when forming a blood drop. You can also experiment with different size lancets to find one that produces the amount you need.

Meter Accuracy Versus Approval Date And Cost

There was a positive correlation between meter accuracy and FDA decision date . A more recent approval date correlated with lower MARD . There was no significant correlation between the cost of strips and the accuracy of the glucose meters .

Relationship between MARD and retail strip price. Meters with MARDs < 10: 1. Contour Next 2. Nova Xpress 3. OneTouch VerioIQ 4. Accu-Chek Nano 5. FreeStyle Freedom Lite 6. Accu-Chek Aviva Plus 7. FreeStyle Lite 8. Nova Nova Max.

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.
