FFS So Abbott’s Libre 3 app, for continuous glucose monitoring, allows itself to be installed on a variety of devices and iOS versions. But should you have issues with it they point you at a doc saying it’s not supported on all devices and OS versions. So be on an insecure OS release (18.0!) or we don’t support you. FAIL

When might they get around to upgrading and fixing their app? No ETA. Critical alerts, DENIED!

I have ended my experiment using a Dexcom Stelo alongside a Libre 3 Plus. I have learned all that I think I care to learn.

The Stelo is removed and no longer contributing to annoyingly inaccurate data.

It lasted longer than 10 days without getting noisy, which was one of the big things I wanted to learn. This means G7 shouldn’t be a big problem. This is important as I will be switching to the G7 when I get my Mobi pump.

I’ve decided Dexcom Stelo is not a good product.

Freestyle Libre 3 Plus is also a 15 day sensor that doesn’t allow calibration. But in my experience, Libre tends to not require calibration as it tends to follow BG fairly well.

This Stelo has been persistently 20-50 mg/dL over Libre 3 and BG.

If this is a common problem, this makes figuring out if the regimen is doing its job way more difficult.

And Libre 3 Plus is cheaper.

So I’ve been running a Libre 3 Plus and Dexcom Stelo on myself for several days. I have Shuggah connected to the Stelo and sending the data to Nightscout while there is a separate “sidecar” service handling the Libre data going into Nightscout. Basically, I can follow the data all in one place within Nightscout even if it’s not really designed for that.

The Stelo is consistently reading higher than the Libre. The range at which it tends to be higher can be just a few mg/dL to as high as 40 mg/dL. Dexcom does a bit more smoothing so rate of change can be slightly slower.

More interesting: who is more accurate? The last 2 blood checks have shown the Libre to be within a few mg/dL.

Neither of these can be calibrated.

I have to switch to G7 (what the Stelo is based on) when I start on a pump, which I believe does allow for calibration.

Disclaimer: Stelo is not meant to be used by people using insulin. I am basing my dosing decisions on my Libre 3 Plus.

Super interesting data and observations! Will be interesting to see how they behave towards the end of their 15 days, as Dexcom’s G7 has struggled to stay consistent for its 10 day life, based on users of that system.

LibreLinkUp US is back!

And yeah, I had a hard drop during the dog walk. Fun stuff.

The Libre 3 app exaggerates the drop a bit, though. Because it has a non-adjustable time view. And it smooths out how low I went.

This is why I prefer using other apps to view my data and get alerts.

Continued thread

The Libre 3 app doesn’t have a rapid fall alert. Just high, low, urgent low, and signal loss. I experience hypos below 80mg/dl. But I can feel them sooner if there’s a rapid drop. Part of it is the drop itself, part of it is CGM lag.

I couldn’t get ahead of this hypo because I use a third party app consuming LLU to help me with this.

I really hate this feeling.

Welp. That sensor failed out. I suspect it couldn't figure out my glucose situation and thought itself to be faulty.

To be honest, after 3 consecutive bad sites, I might just go the rest of the week without a CGM. I'll just have to be mindful about my BG via finger sticks to avoid going hypo, and pay attention to my body.

Today is new sensor day and it's the third one in a row that was a mild bleeder. The last 2 read low. The first one never came up so I removed it. The last one ended up being pretty good.

This one is reading low again. So…another waiting a day to see what happens.

To be clear: This is not a faulty sensor issue. They are not designed to read from blood. This is just really bad luck.

I just learned Abbott has released the Freestyle Libre 3 Plus system.

The Libre 2 Plus had a couple of changes to make it compatible for AID systems. The Libre 3 was supposed to be ready for this, but apparently one more change was, ultimately, needed, likely brought from the Libre 2 Plus.

Reduction in interference from ascorbic acid.

I actually didn’t know this was a problem for AID systems.

I requested my doc to switch me over.

So when a sensor acts particularly wonky, Shuggah (the app I use for diabetes management) has a bad time. The only way to fix it, I've found, is to reinstall it, which causes all the historical data in the app to be lost.

I can't dissociate the old sensor either. It's just...broken until reinstalled.

Why can't things...just...work?

New replacement sensor is starting out the same as the previous: reading way low. While I'm at 190mg/dl (blood glucose reading), it's reading 110mg/dl.

I shall give this it's day and see how it's going tomorrow.

Abbott recently had a recall of 3 lots of Libre 3 sensors. These are not part of the recall. Also the recalled sensors were reading excessively high values, not low.

Seems Abbott might be having a bad time right now.

Yesterday’s new CGM was a bust. It kept reading low, occasionally coming up and falling back down. So I replaced it this morning.

It was a light bleeder when it was inserted so I anticipated a day 1 issue, but it never resolved, and is actually causing problems. So it’s a failed sensor.

There’s a knot where the filament inserted. So probably not a faulty sensor, just a bad site.

Now to wait for the new one. Again.

This new sensor has been annoying today. It read okay initially, but has otherwise been reading low. Not like bottomed out low like a sensor that isn’t able to read, but much lower than my actual BG.

Going to give it until tomorrow to get its act together before I yeet it.
