Urinalysis with GLU 2+, PRO 1+, KET 3+ in the context of hyperglycemia and acidosis most strongly suggests which condition?

Glucosuria with ketonuria in the setting of high blood glucose and metabolic acidosis points to diabetic ketoacidosis. When insulin is deficient, the body cannot use glucose effectively, so blood glucose rises and the kidneys spill glucose into the urine, causing osmotic diuresis and dehydration. At the same time, lack of insulin triggers rapid lipolysis, producing ketone bodies that accumulate and drive acidosis. The presence of ketones in the urine confirms active ketogenesis, which is a hallmark of DKA rather than just high glucose. While acute kidney injury, urinary tract infection, or sepsis can cause abnormal urine findings or systemic illness, they do not typically present with the combination of significant glucosuria and ketonuria accompanied by metabolic acidosis. The pattern described is most characteristic of diabetic ketoacidosis.
