No. Urine is collected over hours in the bladder. If a patient with diabetes has no sugar in the urine that means that blood sugar control from over a few to several hours back was likely not very high. However, it doesn't say anything for the current situation.
Sugar in urine. Not normal. Suggests diabetes.

Peads endo consult. Your child needs to be in follow up of well trained pediatric endocrinologist. Without knowing more specific details I could not give you more information. There could be several causes for low calcium in this age group and this needs to be worked up and he should be receiving appropriate calcium supplementation and may also require Calcitriol (active form of vitamin d) based on the diagnosis.
Low threshhold. Ordinarily the kidney does not spill sugar into the urine until the blood level reaches about 180. However, if this kidney threshhold happens to be set at a much lower level, the sugar will begin to spill at a much lower level. This goes by the scientific name of renal glycosuria and has no relation to diabetes.
Timing. Urine is collected over hours in the bladder. If a patient with diabetes has sugar in the urine that means that blood sugar control from over a few to several hours back was likely high at some point. However, it doesn't say anything for the current situation where blood sugar can certainly be low.
It's possible. Hi. Odd question. It's possible to have a serum glucose over 200 with none in the urine, but the higher above 200 the serum glucose gets, the less likely none shows up in the urine. It has to do with the tubular threshold for glucose, which does show a bell-shaped curve distribution.
3yr old male lethargic, unresponsive. Blood sugar 43, after eating peanut butter and jelly sandwich, apple juice blood sugar up yo 208. Sugar in urine?
Evaluate at hospital. A 3 year old who is truly lethargic and unresponsive should be evaluated at a hospital (such as a children's hospital), arriving there by ambulance. Doctors there will do various tests to see whether or not blood sugar levels are the cause of the symptoms.
