Blood sugar spike while low-carbing?

[Stardew]

I'd really appreciate if someone could help me understand what happened, and why.

I'm newly-diagnosed, probably type 2, and have been eating to my meter. I realised I can tolerate very few carbs, so I'm on about day 3 of drastically-reduced carbs. I have a typical type 2 history (gestational diabetes, pre-diabetes on and off).

I'm testing frequently and I've been very steady all day at around 6.3. I didn't eat at tea time as I was out doing the food shop (ok, I was reading all the labels of everything in Tesco and enjoying the peace and quiet away from my kids).

After doing the shop, I had a snack - a long seafood stick for 6.8g carbs and a Fulfil bar for 11g carbs but 9.2g polyols, so really 1.8g as I understand polyols aren't absorbed.

I tested about an hour later, before dinner, and got a reading of 10.6.

It seems a very large jump for the small amount of carbs I had. I've not experienced that before and it's thrown me as I thought I was doing well.

I'm on 30mg slow release gliclazide and dapagliflozin.

Any thoughts?

Did you retest in case you had something on your finger?

I agree with Antje, my first thought would be a contaminated reading. After that, I would look at other possible causes è.g. Stubbing a toe or banging my funny bone, telephone call from the boss etc. I would then recheck the labels on those snacks

Some of us react to some Polyols, just as if they were sugar. try testing them again, the only way to find out.

Thanks all, I think it must have been a contaminated sample as I checked and double-checked the labels.

I had the same thing today and tested before and after, and got 5.8 for both.
