Food sensitivity testing identifies foods that may trigger adverse reactions in your body, such as bloating or fatigue.
Diagnostic testing is a cornerstone of naturopathic medicine and an essential part of personalized health care at 8 Wellness. Our naturopathic doctors use both conventional and functional diagnostic testing to better understand what is happening inside your body and to identify underlying imbalances that may be contributing to your symptoms.
Rather than guessing or relying solely on symptoms, diagnostic testing allows us to create targeted, evidence-informed treatment plans that address the root cause of health concerns, not just the surface-level presentation.
We offer diagnostic testing for patients in our Oakville clinic as well as virtual patients across Ontario.
Why Diagnostic Testing Matters
Many symptoms, such as fatigue, digestive issues, hormone imbalances, mood changes, or unexplained inflammation, can have multiple possible causes. Diagnostic testing helps narrow down why symptoms are occurring by providing objective information about your internal health.
Testing may help us assess:
- Nutrient deficiencies or excesses
- Hormone imbalances
- Blood sugar and metabolic health
- Digestive and gut microbiome function
- Inflammation and immune activity
- Stress response and adrenal function
This information allows your naturopathic doctor to recommend more precise nutrition, supplementation, and lifestyle strategies tailored specifically to you.
Who Can Benefit From Diagnostic Testing?
Diagnostic testing may be appropriate if you are experiencing:
- Chronic or recurring digestive symptoms
- Low energy, fatigue, or burnout
- Hormonal symptoms such as PMS, irregular cycles, or menopause concerns
- Difficulty losing weight or blood sugar issues
- Skin concerns like acne, eczema, or rashes
- Brain fog, mood changes, or sleep disturbances
- Recurrent infections or immune concerns
Testing can also be valuable for individuals who feel generally well but want a proactive and preventative approach to long-term health.

Types of Diagnostic Testing We Offer
At 8 Wellness, testing is always individualized. Below are the most common types of diagnostic testing we use in clinical practice.
Blood Testing
Blood testing provides insight into many foundational aspects of health. Depending on your needs, blood work may assess:
- Iron and ferritin levels
- Vitamin B12 and folate
- Vitamin D
- Magnesium
- Omega 3’s
- Cholesterol and lipid markers
- Blood glucose and insulin markers
- Thyroid function
- Liver function
- Kidney function
- Cortisol (stress hormone)
- Inflammatory markers (CRP, ESR)
Blood work requisitions can be taken to local laboratories such as LifeLabs or Dynacare, making testing accessible for Oakville and surrounding communities.
Food Sensitivity Testing
Food sensitivities develop over time and contribute to a variety of concerns, like inflammation, fatigue, joint pain, digestive issues, and brain fog. The RMA FST IgG Food Sensitivity test can help identify potential food sensitivities and take the guesswork out of your diet. We offer the following panels:
- Basic food sensitivity panels
- Vegetarian panels
- Enhanced or expanded panels
- Candida-related panels
Results are used to guide dietary adjustments that support healing while maintaining nutritional balance.
Hormone Testing
Hormones play a significant role in energy, mood, weight, sleep, stress resilience, and reproductive health. Hormone testing may assess:
- Cortisol and adrenal stress patterns
- Estrogen, progesterone, and testosterone
- DHEA
- Melatonin
We often use saliva, urine, or dried urine hormone testing (such as DUTCH testing) to evaluate hormone patterns throughout the day rather than relying on a single snapshot.

Digestive & Gut Health Testing
Gut health influences digestion, immunity, inflammation, and even mental health. Stool testing may assess:
- Beneficial and pathogenic bacteria
- Yeast, viruses, parasites, and infections
- H.Pylori
- Digestive enzyme activity
- Inflammation markers
- Leaky gut
- Gluten sensitivity
- Gut immune function
These tests are particularly helpful for conditions and symptoms such as IBS, IBD, GERD, bloating, gas, constipation, diarrhea, reflux, and food reactions. We offer GI MAP, GI360, GI Advanced, and the Comprehensive stool analysis with parasitology. These stool tests look at harmful bacteria, health-promoting bacteria, and your overall gut integrity.
Urine Testing
Urine-based testing provides valuable insight into metabolic and biochemical processes in the body. These tests may assess:
- Organic acids (nutrient metabolism and mitochondrial function)
- Cortisol rhythm and stress response
- Neurotransmitter metabolites
- Detoxification pathways
Urine testing is often helpful for fatigue, mood concerns, chronic stress, and complex or unexplained symptoms.
Specialty & Functional Testing
In certain cases, additional specialty testing may be recommended, including:
- Environmental toxin exposure
- Heavy metal testing
- Advanced cardiometabolic markers
- Other functional assessments based on clinical need
These tests are used selectively and only when they provide meaningful guidance for care.
How the Diagnostic Testing Process Works
1. Initial Consultation
You’ll meet with a naturopathic doctor in Oakville or virtually to review your health history, symptoms, and goals.
2. Personalized Test Selection
Only relevant tests are recommended — no unnecessary labs.
3. Sample Collection
Testing may involve blood, urine, stool, saliva, or at-home collection kits, depending on the test.
4. Results Review
Your doctor will review results in detail and explain what they mean in clear, understandable language.
5. Individualized Treatment Plan
Results guide targeted recommendations for nutrition, supplements, lifestyle changes, and follow-up care.
Functional vs. Conventional Testing
We use both conventional and functional testing to gain a complete picture of health.
- Conventional testing evaluates standard medical markers and reference ranges.
- Functional testing looks at optimal ranges, patterns, and how systems are working together.
This combined approach allows us to identify imbalances earlier and create more personalized treatment strategies.
