The trouble with testing urine for sugar is the "Renal threshold". this is individual and is the level at which excess glucose is not recovered from the blood by the kidneys and "Spills over". there are diabetics with high renal threshold, who have VERY high BGs, but nothing showing in the urine and NON diabetics who have exceptionally low renal threshold and who show glucose in the urine all the time. I have met people with both conditions. If you show diabetes type symptoms, a urine test is a very inadequate test. A finger stick test would show more and even that isn't truly diagnostic. The only 100% certain diagnostic tool is a glucose tolerance test.
