Maximise your nutrition and improve your health

Nutrition is powerful! A few simple tweaks can make a big difference in your body and how you feel. Nutritional testing can help you identify your unique nutritional needs.

Nutrition is important for every body system. Poor nutrition contributes to many chronic diseases. If you struggle with any of the following conditions or are curious about your nutritional status, nutritional testing may be able to help identify the root cause of your ailments:

  • Depression
  • Heart disease
  • Obesity and Type 2 Diabetes
  • Fatigue
  • Weight issues
  • General dietary guidance
  • Malnutrition (often observed in the elderly)
  • Maldigestion/Malabsorption related to the gut
  • Athletic performance
  • Physical trauma/healing

Genova’s nutritional testing provides a more complete assessment compared to what standard labs offer. Personalised recommendations for amino acids, fatty acids, vitamins, minerals, digestive support, and other nutrients are provided. Testing can also reveal toxic exposures and measure your body’s ability to neutralise those toxins.

The benefits of nutritional balance include healthy weight, mental wellness, disease prevention, and increased energy – if you are ready to feel your best, talk with your healthcare practitioner today about nutritional testing.

The Metabolomix+ can be collected completely in the comfort of your own home. It requires a urine sample and if your practitioner orders add-on testing, a bloodspot finger stick, and cheek swab. We have many resources to help make your testing experience a success. Review the Test Preparation tab to learn more about the collection process.


Important Prep Before Patient Takes Test

Certain medications, supplements, and/or foods may impact test results. Please note that the reference ranges were established based on patients who were taking no medications or supplements. In some instances it is unknown what potential impact a medication may have on test results.

Genova never recommends that patients discontinue medically necessary medications or supplements in order to complete testing.

There may be times when a patient may stay on a medication or dietary supplement during testing in order to evaluate its effectiveness. The recommendation to discontinue any substance is intended to establish a baseline finding. While there are no rigid rules on time frames for discontinuing supplements to establish a baseline, some clinicians choose to discontinue 4 days prior to testing. If you choose to discontinue a medication, a good rule of thumb is to take the biological half-life of the drug times 5 to allow for ‘clearance’ before testing. With certain medications, the drug itself may have cleared the body, but the effect of the medication may be longer lasting. Below you will find a list detailing the potential interference or influence of certain substances on the biomarkers.


Dietary Factor Possible Impact on Results
Artificial sweeteners and MSG Artificial sweeteners and MSG are composed of amino acids which can directly impact measured amino acid levels
Eat your usual diet; avoid over-consuming any single food, extreme diets, or engaging in a rigourous activity (i.e. marathon) Extreme diets and activity may impact certain organic acid biomarkers related to the citric acid cycle, neurotransmitter metabolites, dysbiosis markers, or amino acids
Phenol and flavonoid containing compounds in fruits, vegetables, chocolate, and tea can result in elevation of certain bacterial and fungal dysiosis markers on the organic acids profile
Bananas, pineapple, kiwi, plums, avacado, walnuts, and pecans can result in an elevation of the serotonin metabolite 5-HIAA measured on the organic acids profile
Seafood Seafood containing heavy metals such as mercury and arsenic can result in a transient elevation
Six 8-ounce glasses of fluid Creatinine concentration is influenced by fluid intake
Fasting, water allowed only Reference ranges were set based on an overnight-fasted population. Overnight fasting minimises influence of a single meal and provides a “steady diet” sample

Medications and supplements may impact results. The discontinuation of any medication is at the discretion of the clinician, only if medically appropriate.

Medications and Supplements Possible Impact on Results
Valproic acid Direct assay interferent for organic acid xanthurenic acid
Acetaminophen Direct assay interferent for multiple organic acids
Berberine HCl Direct assay interferent for organic acids IAA and 5-HIAA
Antibiotics, antifungals, probiotics, digestive enzymes, acid blocking medications May indirectly influence urinary organic acid markers of malabsorption/dysbiosis

Amino acid levels may be impacted by aminoglycoside antibiotics

Amphetamines, centrally acting medications, antidepressants, Anti-Parkinsonian medications May influence urinary organic acid markers of neurotransmitter metabolism1,2
HMG-CoA-reductase inhibitors (statins) and red yeast rice May indirectly increase urinary organic acid B-methylglutaric acid levels
N-Acetyl Cysteine (NAC) Direct assay interferent for cholesterol and triglycerides add-on tests; may lead to falsely low results
Oral contraceptives, estrogen therapy May increase the organic acid quinolinic acid excretion both from altered tryptophan metabolism directly, as well as the indirect functional vitamin B6 insufficiency3
Quercetin May elevate the organic acid homovanillic acid4
Steroids May lower inflammatory neurotransmitter metabolite quinolinic acid, an organic acid
Diuretics May impact creatinine concentration, thus affecting all urinary biomarker measurements
Fibrates May influence fatty acid levels
In some animal studies, fibrates also impact cellular energy metabolites on the organic acids profile
Kreb’s cycle and amino chelated supplements (i.e. citrate, malate, succinate, glycinate, threonate, and orotate forms of supplements [magnesium citrate], alpha ketoglutarate, and others) May result in elevations of corresponding Kreb’s cycle markers and amino acids
Provocation/chelating agents (i.e. DMPS, DMSA, EDTA, etc.) Reference ranges are based on a non-provoked, non-chelated patient population
Vitamin C May increase urinary excretion of organic acid oxalic acid or lead

Dietary Influences on urinary organic acids:4-16

Urinary Metabolite Common Dietary Sources
Indoleacetic acid High tryptophan intake, green/black tea
Phenylacetic acid Wine/grapes
Dihydroxyphenylpropionic acid Whole-grains, chocolate, coffee, green/black tea, olives/olive oil, citrus fruits (animal studies)
3-Hydroxyphenylacetic acid &
4-hydroxyphenlyacetic acid
Wine/grapes, cranberries, green/black tea, berries, orange juice, grape seed extract
Benzoic acid/Hippuric acid Orange juice, elderberry, huckleberry, food preservative, berries, other flavonoids
Citramalic acid Apples, cranberries, sugar beets
Tartaric acid Wine/grapes, chocolate, food additive/preservative
Malic acid Fruits (apples, pears), vegetables, throat lozenges, syrups, beverages with food preservatives and additives
Homovanillic acid Flavanols including tomatoes, onions and tea
5-hydroxyindolacetic acid Bananas, plantains, kiwi, pineapple, nuts, and tomatoes
Diabetic Patients

Urine glucose is a direct interferent to the lipid peroxides assay. Patients with uncontrolled diabetes and elevated urine glucose may receive a result of ‘not reportable, NR’ for lipid peroxides. Sodium-Glucose Cotransporter-2 (SGLT2) Inhibitors lower blood sugar by disposing of excess glucose via urine.

Urinary Creatinine Levels and Kidney Function

The urine biomarkers are ratioed to urinary creatinine. The urine biomarkers include organic acids, urine amino acids and urine oxidative stress markers. If urinary creatinine is out of range, it can impact the levels of reported urine analytes which are used for nutrient recommendations. The collection instructions recommend not to drink more than six, 8-ounce glasses of liquid (48 ounces) 24 hours prior to sample collection because it can dilute the urine impacting the reported urine analytes. Below are considerations for altered urinary creatinine:

  • Elevated Creatinine: High muscle mass, heavy exercise or increased physical activity, increased protein intake, significant dehydration, and increased renal clearance.
  • Low Creatinine: Poor renal clearance or dysfunction, low muscle mass (i.e. physical inactivity or muscle wasting disease), diluted urine (use of diuretics), malnutrition/protein insufficiency, and hypothyroidism.


We do not recommend urine testing in a patient with known kidney dysfunction, defined by abnormal serum testing.

Paediatric Patients

Testing is not available for children under 2 years old and samples will be discarded. Appropriate reference ranges have not been established for this population. We do not recommend squeezing liquid out of a diaper for sample collection, as this can result in altered concentrations of creatinine and biomarkers. A pediatric urine bag that can be taped to the body is available upon request for appropriate sample collection. While this is not a catheter procedure, instructions for catheterised patients can be followed below with regards to collecting and pooling all urine samples from the child’s bedtime to early morning awakening.

Urinary Catheters

It is unknown whether having a catheter placed will affect the results, or whether there will be any interference or decreased viability of the sample owing to this procedure. It is imperative to collect all urine samples from bedtime until early morning awakening. The bladder should be voided before bed. If the patient urinates during the night, the contents of the bag should be emptied into a clean container and refrigerated as soon as possible. This must be done each time urine is collected during the night. This may be inconvenient for the patient but would ensure a more viable sample. Finally, collect the first urine upon waking for the day, and combine that sample with all samples collected during the night. Ensure the combined sample is well mixed before transferring into the labeled tubes.

Pregnant Patients

The reference ranges were not designed for a pregnant population. However, it may be useful to evaluate functional nutritional needs to optimise health during pregnancy, for both the mother and fetus. In pregnancy, the demand for various nutrients increases dramatically. The recommendations offered may reflect that increased nutritional burden. However, because the reference ranges were not established for this patient population, the implementation of nutrient recommendations or botanicals should be in accordance with standard pregnancy recommendations and precautions.
