Ketones
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Urine ketones are a product of fat metabolism, occurring when the body utilizes fat rather than glucose for energy. In the context of a Urine Routine panel, the presence of ketones (ketonuria) is a critical marker for metabolic derangement. It is most commonly associated with Diabetic Ketoacidosis (DKA), a life-threatening complication of diabetes. It also serves as an indicator of starvation, carbohydrate-restricted diets, or metabolic disorders in pediatric patients. Measuring acetoacetate and acetone levels helps clinicians differentiate between simple hyperglycemia and true ketoacidosis.

Why Context Matters
False positives can occur due to highly concentrated urine, dehydration, or the presence of certain medications such as levodopa, captopril, or sulfhydryl-containing drugs. A second opinion or blood-based Beta-hydroxybutyrate test may be necessary if clinical symptoms do not align with urine results.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
