meter %

[borderter]

Tested bloods tonight after very light lunch and active afternoon was 7.7 on my meter but retested with expert meter and 5.2 which was what I felt it should be
Having noticed higher than expected readings a lot lately contacted roche who said it was within 15% but are sending a replacement anyway as base insulin on readings so didnt feel confident with this level of discrepency so is this within 15% as it boggles my brain trying to work it out

I do not think that it is in the 15% range. At the most generous, the medium of 5.2 and 7.7 is around 6.4. 15% off of 7.7 is 6.55. And 15% off of 6.4 is 5.44. That is the most generous I can get and puts both meters outside of 15% range. There are a lot of other variables though as I am sure you already know but still seems to me to be outside of the 15% range.
