Wildly inaccurate BG readings

science

#21

So based on this I would imagine my readings are just within the margin of error. Though the keto mojo is not shown. I’m seeing 10-15 points which I think is just within the accuracy.

I’m thinking on reading showing on the lower side and one on the higher would give the margin.

It is just a little surprising to see a 66 which is about 10 lower then 'normal ’ fasting bg

Thanks for the info

Like you say, the Keto Mojo isn’t in the list, but 10 or 15 isn’t points isn’t unusual out of 100. At the time, I was using a meter that would give me readings that far apart. Coming from a world where most measurements are within 2%, it makes me nuts.

Somewhere on the forums, I’ve seen discussions comparing the Abbott glucose/ketone meter and people comparing it to the Mojo There’s no equivalent paper for ketone meters that I know of.

Are your test strips properly calibrated?
Are they still in date?
Is it possible the batch is bad (do you have a different batch you can try?)
Did someone (who shall remain nameless, lol) drop the meter on the floor?

P.S.–Good luck figuring it out, Erin. :bacon:

I pay about $75/month for the sensors for the 14-day US version. The Sweden version I got was about $65/month with the exchange rate, and the Swedish version is over the counter (no prescription) and does not need calibration, unlike the US version, which requires calibration using pinprick sensors.

I’d like to see one that does glucose, ketones, insulin, and glucagon.

The 14-day one doesn’t need calibration. It even says so on the website.

Interesting. Mine asks me to use a pinprick stick and actually seems to be wildly inaccurate at first, as in 20 points off, unlike the European version, which was rock solid.

I’ll revisit this once I get another supply of them, which will be soon.

Mine says to do that too, but its only for the first 12 hours or so, as its getting used to my body. Its not required to do finger sticks. They just don’t want you to rely on the sensor for decisions. Mine have been about 5-10 off, or less. But also, they say that there could be a discrepancy anyway, based on the differences in how ISF and BG are measured.

I’ll show you what I mean. Here’s the first time I put the sensor in:

I guarantee that value is way higher than the real reading, as evidenced by the next few days:

So, I’ve been using the pinpricks just to see if I can get the readings closer to reality.

The European model was not like this. I never once looked at it (unless the seal around the sensor went bad) and said, “What the heck?”. But with the US model, the first half day or so is totally out of alignment with reality.

I guess this is even more clear when you look at the rest of the days of that week:

The later days are really what my blood sugar is, considering I’m basically eating meat and eggs, with minor veggies, and maybe some dairy, sometimes.
