Here's a second non-diabetic who tracks their glucose with the same non-invasive device and started analyzing it.

The Freestyle Libre requires a prescription (why?) — is there another similar system that does not?

No. In the US, all similar products require a prescription. This is by far the best available option (no fingerstick calibration, longest-lasting sensor, easy mobile app, etc.). Basically, get this one. It’s $80 including 1 month of sensors. I believe the thinking is that people need a professional to discuss results with. I understand that perspective, but I don’t agree with it, and I definitely don’t agree that hav…

Dexcom has a similar sensor on the market that’s approved for insulin dosing decisions. I don’t know if any of the other continuous monitors have that particular feature which might be important to those who take fast insulins.

It seems to still be invasive: https://www.freestylelibre.us/support/faq.html#faqTabstab-3

> The sensor is applied to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a small (5mm) filament is inserted just under the skin, and held in place with a small adhesive pad.

'Inserted just under the skin' means it's still invasive, but that sounds nicer than regular needle-sticks so perhaps 'less-invasive' would be a more accurate description.

When I lived in Canada I used to occasionally see infomercials about blood sugar monitors that didn't require pricking fingers - are those considered to be any good or is it some kind of infomercial scam? If they are considered to be mostly accurate, why can't that technology be used instead of having a 5mm needle in your body, which probably feels uncomfortable, particularly for the elderly.

Per the people I know who have tried it, including the author of this post, it's totally painless. One can debate whether or not a filament you can't feel is invasive, but for all practical purposes it's the same as no filament.

For clarity: the measurement you pasted is the length of the filament. The width/thickness is ridiculously tiny. Basically, this product has the same UX as a nicotine patch.

I wear a FreeStyle Libre every day, AMA. It's very good for T1s, of course.

It's reliable enough - the biggest downfall is that it's around 15 minutes behind real-time, ie, what you can measure with blood. Sometimes it can feel 'stuck' too, and change rapidly between a short amount of time.

The second model, which I am waiting to try, includes Bluetooth alerts if a trend high or low is detected. This may make it even more useful.

Dexcom G5 and G6 are the best available CGM systems for type 1 diabetics. What they add over the libre is a Bluetooth transmitter over the sensor, giving values to your phone every five minutes. Used together with xDrip and AndroidAPS it can easily safe the life of a person using insulin and not waking up to a hypoglycemia, me included. Or work as a part of a closed loop system.

The problem with Dexcom is the price. A sensor should be replaced every week and costs 80€, the transmitter turns off after three months and costs between 300-400€. If you understand what you're doing, you can easily extend the sensor lifetime to 3-5 weeks and transmitter to 6-8 months.

My take to this is, every T1 deserves a Dexcom system from the insurance. It easily saves your life and makes the control much easier.

Thanks for clarifying.

As a side note, I think this requirement is completely bogus. You should be able to get any "read-only" medical device you want, anytime you want, especially in a country where there is no universal healthcare. I see a contradiction where on one hand the authorities say: we have to protect you so that you don't harm yourself and on the other the same authorities say: your health is your responsibility and we want nothing to do with it.
