Your Gut, Your Foundation for Wellness

Biomarker Testing for Gut Health at InSyght Health

The gut is central to your overall health. It doesn’t just digest food—it supports your immune system, hormone balance, and even your mood. When the gut is out of balance, you may experience symptoms like bloating, fatigue, food sensitivities, or brain fog.

Additional Reading

From Digestion to Immunity

What Is Gut Health Testing?

Our comprehensive biomarker panels evaluate how your digestive system is functioning and how it may be influencing other parts of your health.

These tests can detect imbalances in the gut microbiome, food sensitivities, bacterial or yeast overgrowth, and markers of inflammation. Because the gut plays a central role in nutrient absorption and immune balance, uncovering these patterns provides valuable insight into conditions ranging from fatigue to autoimmune disease.

What Is the Gut Health Testing Process Like?

Simple Tests, Powerful Insights

Gut health testing varies by test type:

  • Comprehensive Stool Analysis – Collects a small stool sample using an at-home kit to evaluate digestion, beneficial vs. harmful bacteria, and inflammation markers.
  • Microbiome Testing – Uses stool samples to map bacterial diversity and balance in the gut.
  • Intestinal Permeability Testing – Blood or urine testing that evaluates for “leaky gut” markers, which may allow unwanted particles into the bloodstream.

At InSyght Health, we provide two tiers of membership to help you understand and address your gut health, overall wellness, and longevity with precision and convenience. Once your samples have been collected, they are sent to certified labs, and results are uploaded to your secure InSyght Health dashboard with clear explanations and guidance.

Finding Your Triggers

Food Sensitivity

A healthy gut often hinges on understanding your individual immune response to food. Our Food Sensitivity Testing provides a precise, data-driven starting point for that understanding. This simple, non-invasive process involves a single blood draw to measure your immune system's reaction—specifically IgG and IgA antibodies—to a comprehensive panel of common foods. Unlike acute allergies, these sensitivities can cause delayed and chronic issues like inflammation, digestive distress, and persistent fatigue. By identifying your hidden triggers, we can craft a personalized plan to calm your immune response and support lasting gut repair.

Diagnostic Clarity

Celiac Disease

For patients struggling with chronic digestive symptoms, obtaining a definitive diagnosis for Celiac Disease is a critical step toward healing. Celiac is an autoimmune disorder where consuming gluten damages the small intestine. Our testing protocols provide the diagnostic clarity needed to confirm or rule out this condition. We use specific blood panels to look for key antibodies (e.g., tTG-IgA, EMA-IgA) that indicate an autoimmune reaction to gluten. If these tests are positive, we will provide guidance on next steps, including genetic testing or endoscopy recommendations, to ensure you receive the precise care required for this diagnosis.

What Conditions Does Gut Health Testing Address?

From Bloatingto Brain Fog

Gut testing can help you find lasting relief from:

  • Chronic bloating, gas, or abdominal pain
  • Diarrhea, constipation, or alternating bowel patterns
  • Food sensitivities or intolerances
  • Fatigue or brain fog linked to digestion
  • Unexplained nutrient deficiencies
  • Autoimmune conditions or chronic inflammation
  • Skin issues like acne, eczema, or rashes

By identifying hidden imbalances, testing helps guide the next steps in care—whether through nutrition, supplementation, or targeted therapies.

Clarity That Supports Long-Term Wellness

What Are the Benefits of Gut Health Testing?

Gut health testing provides more than answers to digestive symptoms—it helps you understand the root causes of issues affecting your entire body. Benefits include:

  • Identifying food triggers and intolerances
  • Detecting bacterial or yeast overgrowth (like SIBO or Candida)
  • Understanding microbiome diversity and resilience
  • Measuring inflammation and gut barrier function
  • Connecting gut health with energy, mood, and immunity

These insights allow for more personalized, targeted recommendations that go beyond trial and error.

Biomarker Testing for Gut Health

Frequently Asked Questions

Can gut testing really identify food sensitivities?

Yes. Blood-based antibody testing (IgG/IgA) helps identify potential food triggers that may cause inflammation or digestive symptoms.

How do I know if I have small intestinal bacterial overgrowth (SIBO)?

A breath test that measures hydrogen and methane gases after drinking a sugar solution can identify bacterial overgrowth in the small intestine.

Is gut testing invasive?

No. Most tests use simple stool, blood, or breath samples collected at home or during a quick clinic visit.

How accurate are gut health tests?

When performed through certified labs, these tests are highly reliable. They provide functional insights your provider can interpret alongside your symptoms.

How long does it take to get results?

Most gut health test results are available in 1–3 weeks, depending on the panel.

Can gut health affect immunity?

Yes. Around 70% of the immune system is housed in the gut, so imbalances can influence inflammation, infection risk, and autoimmune conditions.

Do I need to prepare for testing?

Preparation varies by test type. Some may require fasting or avoiding certain foods. Your provider will guide you.
