Are blood glucose levels at fasting 13-14 hours not as reliable as 8-12 hours?

I decided to check my blood sugar and it was at 100 mg/dl and I think i was fasting around 12-14 hours when I checked it, so it got me thinking it probably was alot higher than at 8 hours, so should i discard this result and do it again after 8 hours? i have an appointment with my endocrinologist next week i am just a bit nervous. thank you.

In my world, the result is the result, so no results should be discarded.

I'm not sure what you are trying to achieve. Are you seeing the Endo for your diabetes? your details don't seem to give me a clue as to what sort of diabetes you have, if any.

No i don't have it but my friend told me to make an appointment in case to see the result and ask to do A1C if possible, i made the appointment because 100 is considered prediabetic as well

Different countries have differing diagnostic thresholds, especially for prediabetes. As your friend has alluded, an A1c test might be a better indicator of what's going on. There are so many factors that can influence blood glucose scores - especially fasting levels.

Personally, I found my fasting levels least informative, in working out my condition. I found pre and post eating more informative, alongside my A1c tests.

I did a lab test and this was the result at 10 hour fasting, now kinda worried since the reference range in their lab is different, shoud l i be worried?

Your finger prick tests are taken from your fingertips, usually, taking capillary blood, whereas labs are usually testing venous blood, taken from a vein.

Lab tests are usually considered to be more accurate.

If YOU have concerns, you really need to speak with a professional, not some stranger on the internet who could be an axe murderer. (I'm not, but I would say that :playful:.)

Oh no i meant the reference range it set at 70-110 in the lab, isn't that weird? since everywhere on the internet it's always been 70-100 that's why I was confused.

The ranges can also vary, from lab to lab, and from time to time.

To set the ranges, they use a known solution to analyse. If they know that fluid is, say, 100, but the lab returnes them at 110, they would either undertake adjustments to their machine, or adjust the range .

All tests, all machines, all have allowable tolerances.

If you start getting into the minutae of all these things, you'll have no life left to do the good stuff.
