Tee2 accuracy

Hi @Sydneyhorn

Sounds like you’ve made a good start. There are a few things to consider about blood glucose readings.

Firstly all meters have an error range of roughly 10-15%, and even testing the same drop of blood with two different strips can produce different readings for this reason. If you get a reading which is a long way off from what you expect (either low or high) the advice is to throughly wash and dry your hands and test again in case anything has contaminated your hands.

Secondly, blood glucose levels can be affected by so many things - food, exercise, stress, illness, lack of sleep and so on. For this reason, they fluctuate constantly and you’re unlikely to get the same readings at the same time every day, especially when first diagnosed and just settling into a routine of management.

You might also want to check out ‘dawn phenomenon’ which explains more about morning readings and why they might vary.

I’d therefore say that the readings you mention are all perfectly plausible.

Are you also testing immediately before you eat, so you can see the impact of your meals?

Hi @Sydneyhorn

As said, a great start

Numbers looking GOOD

Both @catinahat & @Goonergal making great points

Well done you for doing all the right things


I thought the best use of the meter for me was to spot trends. Particularly that morning one.

I too had drops like that, rather unexpected, then the next days would be higher again,

But week by week the average dropped, so the odd one out became the highs, then by the next few weeks, the pattern returns until I got from average 8's down to the 5's on a daily basis each morning

Much like a temperature chart , with highs & lows..it helped me track my averages as the seasons changed, sort of.

As for food, we want the difference between pre food and then 2 hours later
( which is where we'd expect our BG levels to be coming down, IF we didn't have T2D, I believe)

However I have seen & read that some foods may have a quicker spike or even an extended one, So we COULD miss that 2 hour window spike, for some foods

but it is generally 2 hours & test, that seems standard

So it was a useful tool for me daily, but it also helped reassure me, I was on the right track, as I whittled down the bad food list for that weeks / months chart as I matched towards a better HBA1c.

Sounds like you are headed very much in the tight direction.

Good luck on your journey
