When Manual Testing May Be Needed
Sometimes there are inaccuracies in the CGM. In particular, this can happen:
- During rapid changes in blood glucose, such as after eating, taking insulin, or exercising.
- With severe dehydration and excessive loss of water.
For this reason, the Libre reader also has a blood glucose meter in the system. This allows you to perform a finger prick and a blood test if you need to verify the accuracy of the CGM reading.
Other cases where fingerprint analysis is necessary:
- If you are using the FreeStyle Libre 14 Day System and have symptoms of too high or too low blood sugar
- When FreeStyle Libre warns you that it cannot determine where your glucose is changing
If you are using the original FreeStyle Libre and you detect too high or too low blood sugar, set a reminder on the reader to re-scan the sensor soon .
How Does A Flash Glucose Monitor And Cgm Work
Flash glucose monitors and continuous glucose monitors let you check your blood sugar levels without you having to prick your fingers.
You wear a small sensor on your body day and night that reads your blood sugar levels so you can see the information on your mobile, or other device. If someone helps you look after your diabetes, their mobile can be linked up too.
With a CGM and the latest flash glucose monitor , you can also set an alarm to sound if your blood sugar levels go too low or too high.
This can also be set up to sound on someone elses mobile, for example, a parent or carers.
One of the other main benefits of a flash glucose monitor and CGM is being able to review what your blood sugar levels do every minute of the day and night. With the charts and graphs, you can start to see and understand how food, activity, and other things affect your blood sugar levels.
“It’s a real mental health break knowing what your blood sugar levels are doing at any one time.” Matt

Why Flash Glucose Monitoring System
The Freestyle Libre 2 system is one of the only glucose monitoring devices to measure glucose levels every minute. When combined with the 14-day sensor, nearly unmatched levels of accuracy in a wearable CGM are provided. This means that a total of 1,440 readings per day ensure the user is always aware and in control. An optional audible alarm notifies the user through the Libre 2 reader. With a simple swipe of the device real-time measurements and trends are viewable.

Flash Sensors And Cgm Sensors
With a flash glucose monitor, sensors should be worn on the arms only. And we recommend that they arent placed over areas with tattoos as this could impact your results. With a CGM, you can wear the sensor on different parts of the body, such as your abdomen.
The sensors dont normally need to be taken off. You can usually wear them in the bath, shower and during sports. But some people do have problems with them falling off. There are adhesives you can buy to keep them in place.
You cannot remove a sensor for a while once it has come off you need to replace it with a new one.
How often you have to change the sensor will depend on the type of model youre using and the manufacturers instructions. Youll usually need to change it at least once every 14 days.
Its quick and painless to put on a sensor. You insert them just under the skin using an applicator.
How Often Should The Sensor Be Scanned
After a one-hour start-up period, you can instantly get your blood glucose reading by scanning the sensor with your reader or smartphone app.
You can scan as many times as you like, but to collect all the data, it is recommended to scan the sensor at least once every eight hours.
Research from Abbott, the maker of FreeStyle Libre, has shown that people using the sensor scan the sensor more often than they check their blood sugar with a prick, giving them more accurate readings.

Driving And Checking Your Blood Sugars Using A Cgm Or Flash
You can use a flash glucose monitor or CGM to check your sugar levels when driving, but you must confirm your levels with a finger-prick test if:
- your blood sugar level is 4 mmol/l or below
- you have symptoms of a hypo
- your monitor gives a reading thats not consistent with the symptoms youre getting for example, if you feel like youre having a hypo but the reading doesnt show this.

Using The Freestyle Librelink Iphone App
Prior to applying your first sensor, you should download the free LibreLink app for your iPhone. There are a few things you will do during setup of the app, including setting up a free account on the Web. This allows your data to be downloaded and printed later, or you can simply show your phone to your doctor on your next visit. Among other things, you can see graphs of how your glucose levels are doing, view a log book of recent scans, and add notes about meals you have eaten, etc. I have not played with adding notes to the app.
After you have applied a sensor, you will activate the button in the app that allows you to scan a new sensor and go through the process of scanning as though you were taking a glucose reading. It takes one hour for the sensor to be available for actual scanning. The sensor may be less accurate during the first 24 hours of use, but I have found that things settle down more quickly than this. There are times when I have found the reading from the sensor to only be one point off from the results I get with a finger stick and my Prodigy meter.
The log book is very straightforward and lets you review results from scans you have made on any given day.
I have not asked my sighted wife to view graphs of my blood glucose trends, but I plan to do that in the near future in preparation for showing these reports to my doctor. I have not had the FreeStyle Libre system long enough to be able to present these results to my physician.
Establish A Routine For How Often And When You Should Test Your Blood Sugar
Work with your doctor to plan your routine. They may suggest checking it while youre fasting, before and after meals, or before bedtime. Each persons situation is different, so its important to decide on an arrangement that will work for you.
When youve set that schedule, make checking your blood part of your daily routine. Build it into your day. Many meters have alarms you can set to help you to remember to test. When testing becomes a part of your day, youll be less likely to forget.

Tips To Make Glucose Monitoring Easier
Whether youre using a traditional finger-prick monitor or a CGM for your diabetes management, here are some tips to make checking your glucose easier:
- Always wash your hands with soap and water before checking your glucose for a more accurate result. Do not use hand sanitizer before doing finger sticks.
- If inserting a sensor into your skin for a CGM, be sure to wash the area of skin with soap and water and allow it to dry first.
- Change any sensors by the recommended manufacturer time for example, every 14 days for the FreeStyle Libre and every 10 days for the Dexcom G6.
- If using finger strips, you may experience less pain by using the side of your fingertip closer to your fingernail.
- Even if youre using a CGM, you may consider having a traditional meter on hand to double-check your glucose readings. This is in case you experience symptoms of high or low blood sugar despite a normal reading.

The Freestyle Libre Saves Your Fingertips
Traditional CGMs require the user to calibrate the sensor once or twice a day via finger stick. Patients are also advised to verify readings using a finger stick before administering insulin based on their CGMs reading.
This new system represents a leap in technology, in that it does not require regular finger sticks for calibration, as most other CGMs do. The device is factory-calibrated and doesnt require daily re-calibration. Nor does it require a confirmatory finger stick prior to every insulin injection. This makes it unique in the glucose monitoring industry.

Those with Type 1 or Type 2 diabetes must monitor their blood sugar and keep it in check. It’s a huge priority, and while no one loves pricking their fingers all day and testing their blood, it needs to be done. Traditional blood glucose monitors can be a pain, but there is another option. Continuous glucose monitoring systems, aka CGM devices, are much more convenient and can be worn and used for long periods of time. This makes checking your blood sugar a breeze compared to other methods.
“Continuous glucose monitors offer more intensive monitoring of a diabetic patient’s sugar levels,” said Dr. Rebecca Fenichel, an endocrinologist at Westmed Medical Group. “They are particularly well suited to patients who have to check multiple times a day, or to patients who want to get more frequent feedback during the day.”
For this article, we’ve consulted doctors, including Fenichel, and researched the most popular monitors to curate the best continuous glucose monitors on the market for 2022.

The Freestyle Libre Increases Glycemic Control
Studies show that people using this system tend to check their sugars far more often than those who rely on finger sticks to assess their glucose levels. The average during trials was 15 times a day. This frequent testing allows patients to detect trends and to gain a better understanding of how various foods, physical activities, and medications affect their blood sugar.
In the clinical studies Abbott has conducted, people using the FreeStyle Libre experienced greater diabetes control. They spent more time at their desired glucose range and less time either high or low. Larissa Zimberoff said that her A1C dropped to 7.0% after wearing her FreeStyle Libre.
Cost Of Buying A Freestyle Libre
The cost of Freestyle Libre or Freestyle Libre 2 sensors are around £50 every 2 weeks. If you have a compatible smartphone you can just and use your phone to scan the sensor to see the readings. But if you dont, you can buy a small device called a reader, for around £50 and this is a one-off purchase. Speak to your healthcare professional about where you can buy a reader from they can be available direct from the manufacturer , from a pharmacy or online but this can change.

Notes For Buying Online
When browsing for glucose monitors online, youll notice that some versions, such as the Rite Aid TrueMetrix, are available for purchase over the counter, while CGMs, such as the FreeStyle Libre or Dexcom G6, are not.
This is because youll need a doctors prescription to get a CGM system. However, you dont need a prescription for the basic fingerstick meters weve included on our list. With a prescription, you may be able to buy a CGM from a medical supply store online.
If you do decide to purchase a glucose monitor or meter online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately. You might also consider setting up these accessories on an auto-ship basis so you dont run out.
What The Skeptics Say
Some industry experts whove watched this field for many years still insist that it will never happen.
Its the easiest slide-deck pitch to make, but it never seems to go anywhere, said JDRF CEO Dr. Aaron Kowalski, who has been knee-deep in the world of emerging diabetes technology for decades. There are major technology challenges that are so big, and you have to wonder if there is even a need anymore with what we have in diabetes technology today.
Noninvasive still has a lot of challenges, said Dr. Barry Ginsberg, who runs Diabetes Technology Consultants in New Jersey and is considered a premier expert on noninvasive diabetes tech after analyzing this trend for more than a decade. He predicts the market will be dominated by products that are simply less invasive and smaller than what we have now, such as the Dexcom G7 model expected in 2022.
Semiretired industry consultant John L. Smith is another of the foremost experts on this front, author of the seminal paper The Pursuit of Noninvasive Glucose: Hunting the Deceitful Turkey article first published in 2006 and last updated in a 2020-seventh edition.
He writes that one of the most disturbing aspects in this field has been the perennial announcements by young companies that believe theyve reached a solution for PWDs to no longer have to prick their fingers. Without exception, Smith says these announcements have been premature and are meant to generate hype, raising false hopes.
