I have been using FreeStyle Libre for about one week and here are my first impressions.
For those who do not know this innovation from Abbott yet, here is the product description.
In a few words, you wear a 14 day-small sensor on the back of the upper arm. The sensor captures glucose readings day and night. Scanning the sensor with the FreeStyle Libre reader gets the current glucose reading and a trend arrow that shows where the glucose is heading.
No more lancets, test strips and finger pricks.
I have had a very positive feeling using the FreeStyle Libre for a week.
I agree with what most of users say about it. Read for example the interesting and detailed testimony of Mike on his blog
The reader is indeed very easy and intuitive to use.
One button gives access to the scan function and to different reading options such as graphs of glucose history…
The sensor was harmless to applyl and since then I have forgotten that I am wearing it.
The major positive aspects :
Things to improve
– Low with FreeStyle Libre whereas my regular finger meter showed 110 mg/dl.
– 70 with FreeStyle Libre whereas the blood glucose meter showed 150
However the difference between the results then decreased fast. From the second day and since then the difference has been between 5 and 10 %.
Last scan 2 minutes ago : 84 mg/dl with the FreeStyle Libre and 92 mg/dl with the blood glucose meter.
The big difference at the beginning was maybe because the system needed some “time” to work properly. When I installed the sensor, a small quantity of blood went out from the middle of the sensor. It may have influenced the results for a while…
Eventually, from the second day, I have considered the results as trustworthy. Let’s see if it works that good till the end of the test.
It was very easy to use the FreeSytle Libre during moments when using a regular finger meter would have been more complicated.
It’s important to know the glucose level, but for rock climbing, to know where the glucose level is heading, it’s very useful.
– For example I prefered waiting a little while before climbing a route whereas my glucose rate was “ok” around 120 mg/dl. Indeed The arrow was indicating a fast decrease. So I ate something and waited a few minutes for the trend to stabilize before climbing.
– And generally speaking, the trend arrows helped me many times taking the decision to eat glucose or not.
For example 60mg/dl with an arrow showing an Increase, I prefered waiting before eating something. Another scan a few minutes later confirmed me that I did not need something to eat.
On the contrary 80 mg/dl with a fast decrease, I anticipated the hypoglycemia that was about to occur and I ate something.
Since I have applyed the sensor, it has not moved. Even if it touched several times the rock While I was climbing, the sensor did not move. I guess it can resist pretty well to knocking and scratching.
While climbing, a device that enables to have the reader nearby and ready to use. And at the same time that would prevent the reader to fall. A strap attached to the reader for example.
I really like the FreeStyle Libre. I am usually not a fan of sensors and catheters (pumps) that we need to wear all the time. However for a week now I have had forgotten the presence of the sensor on my arm. And how convenient it is !!!!! A great innovation. I still need to discover the different options of the FreeStyle Libre, for example the software, and will write an article about them.
I will also speak about my experience of the FreeStyle Libre while Kitesurfing.
