Hi @GsMom. Welcome to the forum
I’ve been using the G6 since December, and I used the G5 for a couple years before that.
When looking for a discrepancy, was there any reason his bg level should’ve been rising or falling? In general, I expect the G6 to be about 15 minutes behind because it’s measuring changes in interstitial fluid - not the actual bg value. There’s a lag. If you’re checking for a discrepancy, it’s best to wait until he’s been relatively flat on the G6 app for awhile and there’s no reason to expect his bg level should be rising or falling.
Did you test his bg level twice? Not all meters are created equal, and even the best meters can be off by as much as 10%. If I notice a discrepancy between my meter and G6, I always test twice before calibrating the G6.
Also, I believe the G6 is more prone to discrepancies the further out of range a bg value is. I only calibrate and check for discrepancies when I’m in range and flat.
Generally, I would not consider a 20 point discrepancy 7 days in to be THAT far off. I would calibrate it, and then test again 5-6 hours later to see where it’s running. I prefer that my sensor value be within 10 mg/dl, but I’ll settle for 15 mg/dl. There are plenty of small discrepancies that occur even when testing on my meter twice within seconds. At some point, I just have to accept that our measurement tools aren’t perfect and just work with what I have as best I can.
As for the bluetooth problems. Does he have any other devices connected via bluetooth? Those connectivity problems sound very frustrating. Hopefully Dexcom will have some suggestions on how to resolve those.
Also, my sincere apologies for the diagnosis. It sounds like you’ve already learned so much! This forum has been tremendously helpful for me, and I hope it’s helpful to you too. There are a lot of great parents on here going through similar experiences.
