Metabolomix+

Metabolomix+ : A Non-Invasive Personalized Assessment

The Metabolomix+ is a unique combination of nutritional tests that provides an analysis of key nutritional biomarkers. A first morning void (FMV) urine collection, with optional add-on bloodspot finger stick and buccal swab, the Metabolomix+ nutritional test is a non-invasive, patient-friendly way to assess the functional need for antioxidants, B-vitamins, minerals, digestive support, fatty acids, and amino acids. Insights gained from the Metabolomix+ nutritional test allows clinicians to target nutritional therapies to the precise needs of their patients.

Additional markers are available for an even greater overview of a patient's nutritional status with easy to add modules based on a patient's unique needs.

What is a functional nutritional assessment?

Marked accumulation of organic acids in urine can signal a metabolic inhibition or block. The metabolic block may be due to a nutrient deficiency, an inherited enzyme deficit, toxic build-up, or drug effect.

Enzymes that are responsible for metabolizing organic acids are vitamin and mineral dependent. With this, elevations in organic acids can reflect a functional need for these nutrients on a cellular and biochemical level, even despite normal serum levels.1-5 Recommendations for nutrient supplementation based on elevated organic acid results are generated using a literature-based proprietary algorithm.

Traditionally, urinary organic acid assessment has been used in neonatal/pediatric medicine to identify genetic inborn errors of metabolism, with severity depending on the degree and type of error.* In many cases of genetic inborn errors, the enzymatic defect may be compensated for by high doses of specific vitamin and mineral cofactors and/or dietary interventions. Intervention with higher-dose nutrient cofactors may also be effective in cases of decreased enzyme activity due to causes other than frank inborn errors.

* Genova's organic acid testing is not intended for the diagnosis of neonatal inborn errors of metabolism.

Which patients might benefit from functional nutritional testing?

Common clinical indications for testing include:

  • Mood Disorders6,7
  • Mitochondrial Dysfunction8
  • Fatigue9
  • Chronic Stress10
  • Inflammation11

Several diseases are associated with abnormal organic acid, amino acid, and fatty acid levels such as depression, anxiety, cardiovascular disease, neurocognitive decline, diabetes, cancer, anorexia, and many others.12-15

About the Metabolomix+ Profile

The Metabolomix+ Profile report allows for easy interpretation and clinically actionable results. It includes a Suggested Supplement Schedule that provides personalized recommendations based on test results. The Interpretation-At-A-Glance section of the report provides facts related to nutrient function, causes and complications of their deficiencies, and dietary sources.

The Metabolomix+ Profile report categorizes results into several metabolic areas:

    Genova's Methodology

    Urinary organic and amino acids are measured via GCMS, LC/MS/MS and alkaline picrate. Fatty acids are measured via GCMS. Urinary oxidative stress markers are measured using colorimetric, thiobarbituric acid reactive substances (TBARS) and LC/MS/MS. Nutrient and toxic elements are measured using ICP-MS and Kinetic (Jaffe). Reference ranges are age and gender specific and are based on a questionnaire-qualified healthy cohort. Testing is not performed in patients under 2 years old.
