Hello,
I was suspecting that my readings from a Contour Next were too high compared to typical lab results.
Quick history, diagnosed T2 in early January 2023, got a surprise 11.4 in blood sugars and A1C even worse at 10.5 / IFCC 91, with estimated average of 14.1 mmol/L. A radical dietary change followed (no meds). Progress (samples every Saturday since):
Lab Results:
I went to the lab yesterday, took my own machine and asked the nurse to let me use a drop from the vein to compare lab results to my device. She agreed to let me use a spill from when she pulled out the needle from the vein, to get a quick sample into my machine before she applied pressure to the vein as usual.
And using the same blood from the vein showed these results:
Contour Next: 6.7 mmol/L
Laboratory: 4.8 mmol/L
I was suspecting the device (new one with first batch of strips). I'm new to diabetes too... Manufacturer claims 98% of readings will fall within +/- 0.6mmol/L, compared to lab and 100% will fall into +/- 0.8 mmol/L, but this was 1.9mmol/L.
This is my chart of my 28 readings from Contour Next (RED dots mean morning /fasting):
So I am looking for answers, I was trying to learn patterns to regulate my diet, which according to LAb is going awesome (with strict diet). But judging from the chart above, I could have been on the hypo side if we discount the 1.8 mmol difference (just 1 time I know). What should I make of this?
Note, I have lost 16 Kgs in 2 months, diet keto style (max 1200 calories a day), 2 meals a day, less than 10 grams of net carbs a day.
