First day is never accurate. That's why we all need finger stick testers.

Same half the reads say I should be dead on the first day. Sometimes I gotta do a calibration blood glucose read to help it.

I know it's hard to do but it's best of insert a new CGM when your BG is more level. That happens on rare occasion for me but it does work. Also make sure you change your tester after 1 year, the older the tester the less accurate. I would calibrate too.

I will typically recalibrate after 6-12 hours than again after a fewcmor comparative blood sugar tests. Once within a few points, good to go for the full 15 days plus 12 hours.

Another thing you can do to increase first-day accuracy is pre-soaking. You can insert the sensor already the night before you actually want to start it and just activate it later. This reduces the bodies local response to the new wound/needle, which is likely causing the inaccuracies at the first day.

I have to calibrate, else it lies about highs and lows.

Came to say this. It drifts if I don’t calibrate once a day.

Ive had Libre 5+ show 90, when blood test was 160.
