Pyruvate Dehydrogenase Complex Deficiency Assessment

Assesses pyruvate dehydrogenase complex (PDHc) deficiency severity using plasma lactate/pyruvate ratio, CSF lactate, brain MRI findings, and ketogenic diet adequacy monitoring.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assesses pyruvate dehydrogenase complex (PDHc) deficiency severity using plasma lactate/pyruvate ratio, CSF lactate, brain MRI findings, and ketogenic diet adequacy monitoring

Each component has a specific meaning:

  • Plasma lactate/pyruvate ratio — The plasma lactate/pyruvate ratio recorded for the scenario being assessed.
  • CSF lactate — The csf lactate recorded for the scenario being assessed.
  • Brain MRI findings — The brain mri findings recorded for the scenario being assessed.
  • Ketogenic diet adequacy monitoring — The ketogenic diet adequacy monitoring recorded for the scenario being assessed.

Note: Interpret the pdhc deficiency result against the thresholds and context described above.

How to Use

Enter the plasma lactate/pyruvate ratio, CSF lactate, brain MRI findings, ketogenic diet adequacy monitoring for the scenario you are assessing. Assesses pyruvate dehydrogenase complex (PDHc) deficiency severity using plasma lactate/pyruvate ratio, CSF lactate, brain MRI findings, and ketogenic diet adequacy monitoring. Use the pdhc deficiency result to inform your calculation.
