hello, my daughter (age 6) has been complaining about dizziness and headaches. today I randomly decided to take her blood sugar levels (she is not diabetic). it read 12.8. after she ate it went to 6.7 then at an emergency doctor's appointment it read 5.5 and no traces of ketones in her urine. she is scheduled for a blood test at the hospital soon to determine if she is type one or not at all. has anyone had a reading that high and wrong? not sure if the machine is wrong or not.
