I did a Glucose test my self this morning, using two different brand of meter, in the morning before breakfast.
But different brand meter produce different reading (both are newly brought).
Which reading should I trust ?

Note: brand name are purposely hidden.

Hardly a significant difference. Carry on.

Also, you might want to read the manual more closely on finger site preparation, test strip storage conditions, device maintenance, etc.

But if the reading is 5.4, I should start worry already,
because "For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting."(note below)
Reading of 5.4 indicating I am at the border line to become diabetes.
while reading 5.1 indicating I am safe.

Both are fine, the difference is acceptable.

Sometimes 2 consecutive testings with the same meter might show different reading as well. Try to monitor few days to get an average reading.

Obviously, diabetes is not just diagnosed with a single finger prick blood glucose test. Even the prediabetes definition for all intent and purposes takes the same diabetes workup.

Just go to your regular doctor and share your concerns about your diabetes risk.

Dude even if u test 2 times on the same machine it may have different result.

If u really wants high accuracy u should go for blood test. you can claim it under company healthcare benefit

Thats a capillary glucose test. Less precise compare to venous glucose test (the one that been sent to lab).

And of course, different branding has slightly different reading.

Some other reference may also give until 5.5~5.8 before considered diabetes.

It is not a magical number,
like 5.4, no diabetes, viola
5.5 then you are declared as diabetes.
Not like that.

Those number are man-made recommendation, some may give reference 5.5, some may also give 5.6.
If one test is 5.1, another 5.4, I would say, there is nothing to worry.

It is just a reference range, as long as it stay within the range, a 0.1 is not significant number to be worried upon, but it is always good to control blood glucose disregard whether one is diabetes or not.

If really want to have accurate number, go for Hba1c test. This is the most accurate number to know the glucose level.

Please, please, people. Consult your regular doctor on your diabetes risk.

No amount of internet information for the average person is enough to just diagnose diabetes. Not even a single HbA1c blood test result that you got from your doctor. Just look at the professional healthcare guidelines for the Diagnostic criteria for diabetes to see what even doctors have to be cognizant of.

For doctors, the all-important history-taking precedes even pricking a finger.

It's good to be mindful of your health, (in fact, starting a health/symptom diary's the best way to start managing your health) but be aware to not base your planning without input from a professional.
