Nutritional testing looks deeper than routine blood work to show how your body actually uses key vitamins, minerals, and nutrients. In functional and integrative medicine, advanced panels such as the Organic Acids Test (OAT), Genova Metabolomix+, and Genova NutrEval measure dozens of metabolic markers in urine and blood to uncover hidden deficiencies.
By analyzing nutrient metabolism at the cellular level, these tests reveal imbalances that can affect energy, mood, digestion, and immunity. This functional approach helps identify root causes behind symptoms that typical lab tests may miss.
A urine-based test that measures 70+ organic acids to assess gut health, mitochondrial function, and nutrient balance. It can detect yeast or bacterial overgrowth, oxidative stress, and vitamin or mineral deficiencies providing insights to improve energy, mood, and digestion.
An easy, at-home test using first-morning urine (and optional blood spot) to evaluate antioxidants, B-vitamins, minerals, amino acids, and fatty acids. It identifies hidden deficiencies and helps design personalized nutrition plans especially for those with persistent fatigue or chronic issues.
A comprehensive profile combining blood and urine samples to assess over 125 nutritional and metabolic markers. It highlights functional imbalances related to energy production, detoxification, oxidative stress, and toxin exposure.

Nutritional tests are valuable for anyone with chronic or unexplained symptoms. You may be a candidate if you experience:
Studies and expert guidance confirm that functional nutritional testing often benefits people with mood disorders, chronic fatigue, digestive disorders, cardiovascular concerns, obesity, autoimmunity or frequent infections.
Functional nutrient testing offers several advantages:
By pinpointing exactly what your body needs, nutritional testing empowers lasting, root-cause healing rather than symptom management alone.
Nutritional panels can uncover a wide range of issues, such as:
In essence, these tests map your biochemical landscape. They can identify problems like malabsorption, chronic inflammation, or metabolic bottlenecks

1. What exactly does an Organic Acids Test (OAT) show?
The OAT analyzes organic acids in your urine – metabolic “fingerprints” from how your body processes nutrients. It can indicate yeast overgrowth, mitochondrial dysfunction, oxidative stress and more. This helps your provider identify what nutrients (like B-vitamins or antioxidants) your cells need.
2. How do I know if I need vitamin/nutrient testing?
If you have chronic symptoms (fatigue, brain fog, digestive issues, hormonal irregularities, etc.) that persist despite normal routine labs, nutritional testing may provide answers. It’s also useful if you have conditions known to be influenced by nutrition, such as autoimmune disorders or metabolic syndrome. Athletes and those on restricted diets can benefit too.
3. How should I prepare for these tests?
Most require a first-morning void urine after an overnight fast. Avoid certain foods/supplements 48 hours prior (for example, OAT instructions list avoiding apples, grapes, echinacea, ribose, etc.). Follow your provider’s specific prep guidelines. Drinking a normal amount of water is fine; just don’t over-hydrate right before.
4. How long until I get results?
Typically about 1–2 weeks. For example, Genova Diagnostics notes about a 14-day turnaround for NutrEval. You’ll review findings with your practitioner and discuss next steps.
5. Are these tests covered by insurance?
Coverage varies. Many functional tests (OAT, NutrEval, Metabolomix+) are considered “specialty labs” and may not be covered by insurance. However, they are often eligible for HSA/FSA use. Check with your provider and insurance.
6. My blood tests are normal, but I still feel off. Why?
Standard tests measure nutrient levels in blood at one moment, which can miss functional deficiencies. Nutritional testing measures metabolites and cellular markers, revealing hidden insufficiencies that routine labs don’t catch. You can have adequate serum levels yet still lack what your cells need.
7. Can children take these tests?
Generally, nutritional testing panels like these are not recommended for children under 2 years old. Above that age, pediatric doses and interpretation can be used. Always consult a qualified pediatric integrative provider.
8. How do I get Nutritional Testing in Michigan?
Integrative Wellness Centers in Michigan offer these advanced nutritional tests. We can order panels (OAT, Metabolomix+, NutrEval) as needed. Once results arrive, our providers will explain the findings and create a personalized nutrition plan. Get your testing now!
9. What if I’m already taking supplements?
Tell your practitioner all supplements/medications before testing. Some providers recommend stopping vitamin supplements 24–48 hours before collection to prevent skewing results. However, do not stop any critical medications without consulting your doctor.
No more guessing, no more dead ends, no more endless referrals.
