Confusing blood sugar results- Not diabetic

Im a 19 y/o female, who is very active, healthy and has a BMI of 19. As part of a college project I bought a glucose meter and tested my blood glucose. My results surprised me a little. My fasting glucose was 6.1 on 3 separate occasions. A 90 minute post meal test was 9.9, however a 2 hour post meal result was 6.0. I have tested the meter with the test solutions and the results were in range. Im a little confused about these results, I have no other symptoms. Your views are greatly appreciated :) thanks in advance!

Hi

This is a question often asked

The problem with test meters is that they are mass produced and readings can vary from meter to meter. They do not have to be 100% accurate and the meter you are using could be giving an error on the high side. Hospital test meters cost multi millions of pounds and have to be checked for calibration and accuracy around four times every day

I hope this helps

Blood Glucose Meter Accuracy

Expired test strips are a common cause of false readings

Blood glucose meters in the UK should meet the standards set by the International Organization for Standardization (ISO).

However, there are a number of factors which could affect the accuracy of a blood glucose result.

ISO guidelines state that blood glucose meters should provide results which fall between the upper and lower error bounds, given in the table below, 95% of the time:

  • Within ± 0.83 mmol/L of laboratory results at concentrations of under 4.2 mmol/L
  • Within ± 20% of laboratory results at concentrations of 4.2 mmol/L or more
 
However - lots of us are using the meters for day-by-day checking of blood glucose!

Lots of T2 diabetics have no symptoms and the diagnosis can come as part of being checked out for all sorts of medical conditions. You could go to your GP with the results and see what's said there.

Meter reading accuracy is proportional to the error factor. If the meter has an error of 20% then it could be overreading by 1.0
Even using the test solution does not correlate or coroberate the meter readings

I agree with previous posters "if in doubt check it out with your G.P".

Thank you for the replies! Are you saying that my results are normal and i shouldn't worry? or should i go to the GP to get it checked?
