Your blood sugar is a separate matter from urine glucose levels. This is
unnecessary unless you already ARE a diabetic in which case you've got
bigger problems than a 3rd class medical.

Typically glucose does not "spill" into the urine unless your blood
glucose exceeds 200-250. Normal is in the 80-100 range, and its not
uncommon to find diabetics on tight control who keep their sugar under 120.

ANY detectable glucose in the urine means your blood glucose is too
high. Your blood glucose wont get THAT high regardless of your intake
unless you have ineffective glucose production or utilization.

I would bet your doc can tell you are fasting when you take your test.
When you dont consume glucose, you burn fat, which causes ketones to be
produced. Ketones are READILY excreted in urine, and are also tested for
on pretty much any urinalysis or urine dip/screening.

That's why I never eat or drink anything other than water before the
test. After a meal your blood suger will read higher. It would really
be crappy to fail that little test and spend 6 months trying to prove
to the FAA that you are not diabetic.
