A NATUROPATHIC APPROACH TO
FUNCTIONAL MEDICAL TESTING
Hormone Testing, Stool Testing, SIBO Breath Testing & Food Intolerance Assessment
Functional Medical Tests
Virtual appointments for functional medical testing in Ontario.
At Sequence Wellness, we use evidence-informed laboratory testing to help identify the root causes of fatigue, digestive symptoms, hormonal changes, skin conditions, and chronic inflammation. Testing is never the starting point, but when used appropriately, it provides the clarity needed to create a personalized, highly effective treatment plan.
All testing is carried out by our licensed naturopathic doctors and is available to patients anywhere in Ontario, using local-to-you Lifelabs and Dynacare locations, and/or convenient at-home kits.
Why Functional Testing Matters
Many patients come to us after being told:
“Your bloodwork looks normal.”
“There’s nothing wrong with you.”
“It’s just stress / IBS / hormones.”
Yet they continue to experience symptoms that significantly impact quality of life.
Functional testing helps uncover patterns that standard bloodwork may overlook, including:
- Microbiome imbalances
- Digestive enzyme issues
- Chronic inflammation
- Nutrient deficiencies
- Hormone fluctuations
- Food intolerances
- Motility problems
- Hidden infections
- Gut permeability markers
Testing is always individualized—and only recommended when it will meaningfully guide treatment.
Types of Testing We Offer
Below is an overview of the most common functional tests used at Sequence Wellness.
Hormone Testing
Hormone testing may include:
- Estradiol
- Progesterone
- Testosterone
- DHEA
- LH / FSH
- Prolactin
- SHBG
- Cortisol (serum or salivary rhythm testing)
- AMH
Testing helps us understand symptoms related to:
- Perimenopause
- Menopause
- PMS / PMDD
- Cycle irregularities
- Hormonal acne
- Low libido
- Sleep disturbances
- Fatigue
- Mood swings
- Hair and skin changes
When is hormone testing helpful?
- When symptoms are unclear or fluctuating
- When considering bioidentical menopausal hormone therapy (BHRT)
- When thyroid or adrenal patterns may be involved
Thyroid & Metabolic Testing
Thyroid imbalances are common contributors to fatigue, mood changes, weight shifts, hair loss, and digestive symptoms.
Testing may include:
- TSH
- Free T4
- Free T3
- Anti-TPO antibodies
- Anti-thyroglobulin antibodies
- Thyroid-related nutrient levels (iron, B12, vitamin D)
We also evaluate metabolic markers, such as:
- Fasting glucose
- Insulin
- HbA1c
- Lipid profile
Digestive & Stool Testing
Comprehensive stool analysis helps identify:
- Bacterial imbalances
- Parasites
- Yeast / fungi
- Inflammation
- Gut immune function (secretory IgA)
- Digestive enzymes
- Bile acids
- Short-chain fatty acids
- Occult blood
At Sequence Wellness, we commonly use:
- GI-MAP®
- CDSA panels
Stool testing is particularly helpful for:
- IBS
- IBD (co-managed)
- Chronic bloating
- Loose stools or constipation
- Skin conditions (acne, eczema, psoriasis)
- Unexplained fatigue or inflammation
- Recurrent digestive infections
SIBO Breath Testing
Used to diagnose:
- Hydrogen-dominant SIBO
- Methane-dominant SIBO (IMO)
- Hydrogen-sulfide SIBO (when available)
Testing options include:
- Lactulose breath test
- Glucose breath test
- FoodMarble™ at-home monitoring
SIBO testing is recommended when patients experience:
- Bloating shortly after meals
- Excessive gas
- Constipation or diarrhea
- IBS symptoms
- Rosacea associated with gut symptoms
- Unexplained abdominal discomfort
Food Intolerance & Immune-Based Testing
We use several approaches depending on symptoms:
a. Lactose / fructose intolerance testing
Via serum glucose or breath analysis.
b. IgG food sensitivity testing
- Useful in select cases, including:
- Migraines
- Eczema / psoriasis
- Joint pain
- Chronic fatigue
- Autoimmune conditions
- Digestive symptoms with unclear triggers
c. Guided elimination diets
Often the gold standard, especially when done with practitioner support.
Nutrient Status Testing
Symptoms like fatigue, hair thinning, low mood, and poor immunity may be related to nutrient levels.
We often test:
- Iron / ferritin
- Vitamin B12
- Folate
- Vitamin D
- Magnesium (RBC)
- Zinc
- Omega-3 index
Patients are often surprised by how much better they feel once deficiencies are addressed.
Additional Testing (When Clinically Indicated)
Depending on your symptoms, we may also evaluate:
- CRP / inflammatory markers
- Liver enzymes
- Sex hormone binding globulin
- Prolactin
- Autoimmune markers
- H. pylori (stool or breath test)

FAQ
Do you offer virtual appointments?
Yes! Most of our appointments are virtual. However, we will soon be returning to the office, and will be able to accommodate some in-person appointments in Ottawa, Mississauga, and Toronto.
Do you offer in-person appointments?
Yes! Most of our appointments are virtual, but we offer in-person appointments in Ottawa, Mississauga, and Toronto (Distillery District).
How lab testing works if I live outside Ottawa
There is no obstacle to getting lab testing if you live outside of Ottawa (or one of our other in-person locations – Mississauga and Toronto). We rely on Lifelabs and Dynacare for lab specimen collection, and they have locations across Ontario. GTA patients can access over 150 Dynacare collection sites for instance.
What about physical exams?
As we do mainly hormonal health, digestion and burnout, most of the relevant objective information comes from lab testing. In addition, most of our patients have already seen their medical doctor who has performed a physical exam with no relevant findings. There are some circumstances when physical exams are warranted, and in these cases we ask the patient to come into one of our offices (Ottawa, Mississauga or Toronto – east), or we refer to another practitioner local to them (their family doctor, nurse practitioner or another ND).
