Laboratory and metabolic investigations

Area of Science:

• Biochemistry and Genetics
• Clinical Diagnostics
• Mitochondrial Medicine

Background:

• Mitochondrial disorders present with significant clinical variability and overlap with other genetic conditions, complicating diagnosis.
• Relying solely on abnormal metabolic markers is insufficient, as mitochondrial disease can occur with normal results.
• Existing diagnostic guidelines vary, necessitating a standardized approach.

Conclusions:

• The consensus guidelines provide a structured approach to metabolic investigations for suspected mitochondrial disease.
• A combined strategy utilizing clinical assessment, targeted metabolic profiling, and genetic testing is crucial for accurate diagnosis.
• The guidelines emphasize a genetic-first approach, reserving invasive procedures for non-diagnostic genetic testing.
