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:
COMPONENTS
Organic Acids
- Malabsorption and Dysbiosis
- Cellular Energy and Mitochondrial Metabolites
- Neurotransmitter Metabolites
- Vitamin Markers
- Toxin and Detoxification Markers
- Tyrosine Metabolism
Amino Acids
- Nutritionally Essential Amino Acids
- Nonessential Protein Amino Acids
- Intermediary Metabolites
- Dietary Peptide Related Markers
Oxidative Stress Markers
+ COMPONENTS
Essential and Metabolic Fatty Acids - Bloodspot (if selected as add-on profile)
- Omega 3 Fatty Acids
- Omega 6 Fatty Acids
- Omega 9 Fatty Acids
- Saturated Fatty Acids
- Monounsaturated Fatty Acids
- Delta-6 Desaturase Activity
- Cardiovascular Risk
Nutrient and Toxic Elements (if selected as add-on profile)
Genomics (if one or more of the following SNPs are selected as add-ons)
- APO E (C112R + R158C)
- MTHFR Combined (A1298C + C677T)
- TNF-α
- COMT (V158M)
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.
