Ketones (Urine)
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
In a Complete Urine Examination, the presence of ketones (ketonuria) indicates that the body is using fat for energy instead of glucose. This occurs when insulin levels are insufficient or when carbohydrate intake is severely restricted. It is a critical marker for diagnosing Diabetic Ketoacidosis (DKA), monitoring weight loss, or assessing metabolic stress during pregnancy and acute illness.

Why Context Matters
False positives can occur with highly pigmented urine or medications containing sulfhydryl groups (e.g., Captopril, Levodopa). Dehydration can also artificially concentrate ketone levels, leading to overestimation of metabolic severity.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
