Mitochondrial Metabolites, Plasma
Use
This test is useful for monitoring patients with mitochondrial disorders, organic acidurias, and ketone body disorders. Mitochondrial metabolites occur as physiologic intermediates in various metabolic pathways. Disorders involving these pathways may result in abnormal accumulation of metabolites. This test aids in evaluating abnormal plasma concentrations of metabolites linked to mitochondrial diseases, organic acidurias, and ketone metabolism deficiencies. It should be used as part of a broader diagnostic workup for these conditions.
Special Instructions
Not provided.
Limitations
The test is intended to complement other diagnostic evaluations and should not be used in isolation for diagnosis. An interpretive report based on pattern recognition is provided, but individual quantitative results alone do not conclusively establish a diagnosis. Independent biochemical or genetic analyses are recommended to confirm diagnoses. Some metabolites may interfere with the quantitation of others, and such interferences will be noted in the report.
