Dexcom One + wildly different readings to actual levels

[timbo_dolman]

I found a Decom one+ quite accurate when calibrated against fingerprick tests. What I would say is when you first insert the sensor to give it 36 hours for its stabilise as it can give spurious readings, for example my sensor went from 6.8 to 2.3 and back up to 11.8 all in 24 hours, but then it stabilised to where I expected it to be.
