Urine Acetone (Ketone) is a test that measures the presence of ketones, specifically acetone, in the urine. Ketones are produced when the body breaks down fat for energy, typically during periods of fasting, prolonged exercise, or carbohydrate deficiency. Elevated ketone levels can indicate conditions like diabetic ketoacidosis (DKA), uncontrolled diabetes, fasting, or a low-carbohydrate diet. This test is commonly used to monitor patients with diabetes or to assess metabolic conditions.
