Digestive Health Testing

Standard testing often does not assess functional gut issues. We use advanced stool analysis, breath testing and blood panels to investigate the underlying contributors to your digestive symptoms.

Why Standard Gut Testing Falls Short

If you've been told you have IBS, you've likely been given a diagnosis of exclusion, meaning they ruled out the serious stuff and stopped looking. IBS is a description of symptoms, not a root cause. Bloating, pain, constipation, diarrhea, these all have underlying drivers that the right testing can identify.

Standard digestive testing typically includes a colonoscopy (to rule out IBD or cancer) and maybe a celiac blood test. While important, these tests miss the functional issues that cause the majority of chronic digestive complaints: bacterial overgrowth, dysbiosis, food sensitivities, enzyme deficiency and intestinal permeability.

What Standard Testing Misses

Small intestinal bacterial overgrowth (SIBO)

Present in up to 50% of IBS patients, rarely tested

Gut microbiome imbalances

Dysbiosis, parasites and opportunistic organisms

Food sensitivities (IgG)

Delayed reactions that are impossible to identify by symptoms alone

Digestive enzyme deficiency

Low pancreatic elastase means poor breakdown of food

Digestive Health Testing Options

We select the tests most relevant to your symptoms and history, not a one-size-fits-all panel.

GI-MAP

GI-MAP Stool Analysis

The gold standard in comprehensive stool testing. Uses DNA-based PCR technology to identify bacteria, parasites, fungi, viruses and digestive markers with high accuracy.

Method: qPCR DNA analysis
Reveals: Pathogens, dysbiosis, inflammation, digestion
IgG

Food Sensitivity (IgG)

IgG food sensitivity testing identifies delayed immune reactions to foods. Unlike food allergies (IgE), these reactions can occur 24–72 hours after eating, making them nearly impossible to identify through elimination alone.

Tests: 120–200+ foods
Best for: Bloating, skin issues, migraines, fatigue
SIBO

SIBO Breath Test

A take-home breath test that detects bacterial overgrowth in the small intestine. Measures hydrogen and methane gases produced by bacteria after a lactulose challenge.

Method: Lactulose breath test (at home)
Types detected: Hydrogen, methane, hydrogen sulfide
tTG

Celiac Screening

Blood testing for celiac disease including tissue transglutaminase (tTG-IgA) and deamidated gliadin peptides. An estimated 1 in 100 Canadians have celiac, but most are undiagnosed.

Key markers: tTG-IgA, DGP-IgG, Total IgA
Note: Must be eating gluten for accurate results
Zon

Intestinal Permeability

"Leaky gut" markers including zonulin, a protein that regulates tight junctions between intestinal cells. Elevated levels indicate increased permeability linked to autoimmunity and inflammation.

Key marker: Zonulin
Associated with: Autoimmune risk, food reactions
PE-1

Pancreatic Elastase

Measures your pancreas's ability to produce digestive enzymes. Low levels mean you're not breaking down food properly, leading to bloating, gas and nutrient malabsorption.

Normal: >200 µg/g stool
Insufficient: <200 µg/g (enzyme support needed)

Your Gut Affects Far More Than Digestion

The gut is often called the "second brain", and for good reason. It houses 70% of your immune system, produces 95% of your serotonin and communicates directly with your brain through the vagus nerve.

This means that gut dysfunction doesn't just cause bloating and stomach pain. It can drive anxiety, depression, skin conditions, autoimmune disease, hormonal imbalances and chronic fatigue. Many patients come to us for non-digestive symptoms and discover their gut was the missing piece all along.

Finding and fixing the root cause of gut dysfunction, whether it's SIBO, dysbiosis, food sensitivities or intestinal permeability, can have profound effects on your overall health.

Conditions Linked to Gut Health

  • Anxiety, depression and brain fog (gut-brain axis)
  • Eczema, acne and psoriasis (gut-skin axis)
  • Autoimmune conditions (Hashimoto's, RA, celiac)
  • Hormonal imbalances (estrogen recirculation)
  • Chronic fatigue and low energy (nutrient malabsorption)
  • Frequent infections (immune system compromise)

Signs You May Benefit from Digestive Testing

Digestive Symptoms

  • Chronic bloating or gas
  • Constipation, diarrhea or alternating both
  • Abdominal pain or cramping
  • Acid reflux or heartburn
  • Nausea after eating
  • Undigested food in stool

Related Symptoms

  • Skin issues (eczema, acne, rashes)
  • Brain fog and fatigue after meals
  • Anxiety or mood changes
  • Joint pain or body aches
  • Frequent colds or infections
  • IBS diagnosis without clear answers

Digestive Health Testing Access in Nova Scotia

Gastroenterology wait times in Nova Scotia can stretch to 12 months or more, and when you do get seen, the focus is typically on ruling out serious pathology, not identifying functional causes. If your scope comes back "clear," you're often told to manage symptoms with fiber and stress reduction.

  • Comprehensive stool analysis (like GI-MAP) is not available through MSI
  • SIBO breath testing is rarely offered through conventional channels
  • Food sensitivity testing (IgG) is not recognized or available in standard care
  • Functional gut markers like zonulin and pancreatic elastase are not routinely tested

Through our practice, you can access advanced digestive health testing without a gastroenterology referral. We identify the underlying drivers of your symptoms and create targeted treatment plans to restore gut health, not just suppress symptoms.

Getting Started

Digestive health testing is tailored to your symptoms. We'll discuss your history and recommend the most appropriate tests during your initial consultation. Most extended health insurance plans cover naturopathic consultations.

Frequently Asked Questions

What's the difference between food allergies and food sensitivities?

Food allergies (IgE) cause immediate reactions, think hives, swelling or anaphylaxis. Food sensitivities (IgG) cause delayed reactions that can take 24–72 hours to appear, making them nearly impossible to identify without testing. Symptoms include bloating, headaches, fatigue, skin issues and joint pain.

What is SIBO and how is it tested?

SIBO (Small Intestinal Bacterial Overgrowth) occurs when bacteria that normally live in the large intestine migrate into the small intestine. It causes bloating, gas, pain and altered bowel habits. Testing involves a take-home breath test where you drink a lactulose solution and collect breath samples over 2–3 hours. The test measures hydrogen and methane gases produced by the bacteria.

Is the GI-MAP stool test different from a regular stool test?

Yes, significantly. Standard stool tests ordered through MSI use culture-based methods that miss most organisms. The GI-MAP uses quantitative PCR (DNA-based) technology, which is far more sensitive and accurate. It tests for over 30 pathogens, parasites and opportunistic organisms, plus markers for digestion, inflammation and immune function, all from a single stool sample collected at home.

Do I need a referral for digestive health testing?

No. You don't need a gastroenterologist or family doctor referral. As a naturopathic doctor, I can order all of these tests directly. Many patients come to us specifically because they've been waiting months for a GI specialist or have been told their standard testing is "normal."

Can gut health really affect mood and anxiety?

Absolutely. Your gut produces approximately 95% of your body's serotonin and communicates directly with your brain through the vagus nerve (the gut-brain axis). Gut dysbiosis, intestinal permeability and inflammation have all been linked to anxiety, depression and cognitive issues. Many patients report significant mood improvements after addressing gut imbalances.
