  • There are three types of Ketones beta-hydroxybutyrate (BOHB), acetone (Ac) and acetoacetate (AcAc).
  • AcAc is measured in the urine
    • Easy and cheap
    • Not accurate (semi-quantative) but image analysis (KetoAnalysis) helps
    • Urine levels may not reflect blood levels of AcAc
      • Kidney function
      • Time delay
    • Hydration levels change measured values
    • False positives (trace level) from pigmented urine
    • False positives from vitamin C, medication, etc.
    • Levels of AcAc can be quite different to BOHB levels
  • BOHB is measured in the blood
    • Slightly painful
    • Expensive
    • Accurate
    • Recommend meter and sources.
  • Acetone can be measured in the breath
    • Not readily available – experimental
    • Unclear what the cost will be
    • Overcomes problem of kidney filtration seen with Urine AcAc measurement
    • Some delay between blood ketone changes
    • Levels of Acetone and AcAc can be quite different to BOHB levels
