how would a 21 hour fast affect a blood glucose test?
At 4:30 in the afternoon my husband had a blood glucose test after a 21 hour fast and working all day in construction, it was 6.2. Does this indicate he is diabetic?
Didn’t your doctor explain the results? If not, I think you better get a experts opinion.
That said, here’s my non-expert opinion; its a bit high considering but not diabetic high. I expect a normal fasting result to be more like a 4 or low 5 but if it was diabetes then it would be much higher. Possibly indicates pre-diabetes or diabetes that has been caught early. I think you should ask for a GTT to be sure as you can’t really diagnose off a fasting test.

A 6.2 after a 21 how fast is a bit too high . it should have been more like 5.1 or even 4.8.
But this COULD be normal for your husband (a 21 hour fast and working construction is NOT a healthy habit, by the way . . . .). that is why diabetes is NEVER diagnosed with ONLY ONE glucose reading. Diabetes is diagnosed this way:
"If any two FASTING blood glucose readings are above 6.0, then Diabetes Mellitus should be considered."
In the above, the doctor should THEN perform the Glucose Tolerance Test in his office to provide a complete confirmation.
