Hi
@Davkay70, Welcome to the site !!
Again just to clarify: what type of diabetes have you been diagnosed with ??
Now from my experience as a Tye 1 diabetic, not as professional advice or opinion:
Finger prick blood test readings can vary:
# If there is any sticky lolly residue, which might contain glucose on one's fingers, that will give a falsely high reading.
So washed hands, fingers, dried off before testing.
# glucose meters have an error rate which means that compared to a set standard their results might be
+ or - a certain percentage. The standard for new machines is supposed to be +/- 5 % but in the past some machines
have been +/- 12 to 15 %..
Even so if your machine was reading 13 mmol/l from your son's drop of blood at an error rate of 15% that is about
11 to 15 mmol/l which is still looks outside the normal range..
(I am using the blood sugar levels (BSLs) quoted on the Home page of this site , under the Living with Diabetes heading,
fat left)
# Of course the timing of the test in relation to food is important:
You will see under Type 1 diabetes, BSLs levels that there is a fasting test levels, on waking up, before any food etc
and another one at least 90 minutes after food.
Sometimes a BSL reading taken 45 to 80minutes after a meal can be higher for various reasons and is not used for testing
except for during pregnancy.
But please record any such results from your son and mention those to your GP too just to be sure.
Please be mindful that finger pricks do hurt, but I hope that gives you some background about testing.
Of course you need to discuss what you are doing and what results you obtain with your GP.
And be mindful not to become too distracted and not look after your own diabetes !!
Best Wishes
