Ketones

Ketones are compounds produced when your body breaks down fat for energy, typically during fasting, intense exercise, or low-carbohydrate diets. A urine ketone test detects these compounds in your urine. Elevated ketones may indicate ketosis (a normal metabolic state during certain diets), diabetic ketoacidosis (a serious condition in diabetes), starvation, or metabolic disorders. Trace amounts are usually not concerning, but significant elevation warrants medical evaluation.
