How is a urinalysis test related to type 1 diabetes?

Sugar runs thru you. The term diabetes mellitus translated means: sugar runs thru you. In years before labs the doc could smell the sweet odor on a diametics breath & verify their suspicion by touching a dab of their urine to their tongue. If your sugar lever is up it spills into the pee and a urinalysis can pick it up.
Was used to.. Monitor diabetes control in past, but not patients do fingerstick sugar testing urines though are still used to check for 'ketones' by the patient, a warning that sugar is very poorly controlled, may have 'ketoacidosis, need to go to emergency room!
