That looks like possibly an incorrect test maybe something on your finger or lancet that has corrupted the reading if I get a number as high as that I always ensure I recheck after washing hands and changing lancet which may help I also had an accu check Xpert but the DSN really didn't like it I still use it as a meter as I like the size of it but I am now on a pump and can't believe the difference hba1c has dropped from 77 to 50 in 4 months
Good luck with the pump
