• Evaluates fatigue, regression, muscle weakness, or multi-system issues that don’t fit a single diagnosis.
• Conducted by a metabolic specialist or neurologist, often including blood, urine, and sometimes muscle or genetic testing.
• Key Outcome: Report detailing enzyme activity levels, mitochondrial markers, and recommended diet or medication plans.
