CDI offers products and services that aid the diagnosis of small intestinal bacterial overgrowth (SIBO) and irritable bowel syndrome (IBS).

Founded in 2015 in Salem, Mass., and operating out of its CLIA-certified laboratory and as an FDA-registered, ISO 13485-certified medical device manufacturer, Commonwealth Diagnostics International (CDI) helps providers identify and diagnose common sources of digestive distress and functional gastrointestinal ailments. CDI’s expansive portfolio of non-invasive at-home hydrogen and methane breath tests supports the diagnosis and treatment of Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO), as well as fructose malabsorption, lactose malabsorption, and sucrose malabsorption. Focused on patient-centric principles, CDI breath tests are easy-to-use, quick, and safe for patients and support meaningful GI health outcomes by helping steer each practitioner’s approach to dietary modification, homeopathic remedies, nutritional supplementation, immune support, high-quality probiotics, and additional testing.

A Simple Water Rinse Can Improve Early Readings

Did You Know? A quick water rinse before each sample helps reduce oral fermentation effects on early hydrogen values—supporting cleaner baselines and more interpretable curves. It’s one of several small steps that boost accuracy.

Precision You Don’t See: How We Prevent Instrument Drift

Lesson from the Lab: Subtle analyzer drift can skew gas values. CDI combats this with NIST-traceable calibrations, built-in drift checks, and automatic re-runs on flagged samples to ensure reproducibility.

Result: High-fidelity curves you can trust—first time and every time.

🌟 Functional Friday Recap — Modern Gastro Podcast, Ep. 2 🌟
Theme: Moving beyond “guess-and-check” to evidence-based, patient-centered GI care

🎥 Clip highlight:
“Patients come to a doctor hoping for a clean diagnosis and a single prescription… but we’re often still defaulting to a guess-and-check model in today’s practice. That conversation is a challenge—though there’s real hope for the future.”
Why this matters: Too many patients with functional GI symptoms feel stuck—bounced between tests, trials, and temporary fixes. In Episode 2, host Craig S. Strasnick digs into how we shift from trial-and-error to standardized, validated care pathways that actually change outcomes.
What we unpack in Ep. 2
Replace guesswork with validated diagnostics: Hydrogen + methane breath testing (aligned to North American Consensus & ACG guidance) narrows the differential for SIBO, IMO, and carb malabsorption—and informs targeted therapy.

Name the gap, build trust: Being honest about uncertainty builds credibility. Clear expectations + transparent plans = better adherence and fewer repeat visits.

Treat the system, not just the symptom: Add GI dietitians (low-FODMAP done right, staged reintroduction), GI behavioral therapies (gut-directed hypnosis, CBT, breathing), and motility-focused care when indicated.

Tighten the workflow: Precise patient prep, 15–20 min sampling over 2.5–3 hrs, methane measurement, CO₂ correction, and rapid reporting turn data into decisions—fast.

Practical takeaways for providers
Use hydrogen + methane (not hydrogen-only) tests to avoid missed IMO.

Prioritize patient education + kit registration to boost compliance and reduce retests.

Embed dietitian + GI psychology referrals into your default pathway for IBS/SIBO-like presentations.

Document timing, prep, and meds to protect interpretability and reproducibility.

Why Breath Testing is Just the Beginning
🎙️ Modern Gastro Podcast Ep 1 | The Gut‑Brain Link & GI Health

Breath tests are powerful diagnostic tools for SIBO, IMO, and carbohydrate malabsorption.
But here’s the thing: They tell you WHAT is happening, not WHY it’s happening.

In this episode, host Craig Strasnick explores how pairing breath testing with behavioral and dietetic interventions creates a whole‑patient model of care.

🔍 Key insights:

A positive SIBO test without motility evaluation is like finding a leak but ignoring the pipe.

Gut‑brain therapies can break the cycle of recurrent symptoms by calming the nervous system.

Dietary strategies work better when the brain‑gut conversation is balanced.

📋 Provider takeaway:
Start with evidence‑based diagnostics. Then integrate psychological and nutritional interventions for a truly functional GI care plan.

The Future of Functional GI Care
🎙️ Modern Gastro Podcast Ep 1 | Craig Strasnick on Gut‑Brain Integration

Functional GI disorders like IBS and SIBO often get trapped in a test–treat–repeat cycle.
Why? Because too often, we’re treating the symptom, not the system.

In this episode, Craig breaks down how the future of functional GI care depends on:
1️⃣ Accurate diagnostics (hydrogen & methane breath testing)
2️⃣ Multidisciplinary care teams (GI providers, dietitians, psychologists)
3️⃣ Patient‑centered planning that addresses both physiology and behavior

💡 Key moment from the episode:

“We can’t just rely on tests and medications. We have to restore healthy communication between the gut and brain.”

📈 Impact for providers:
Patients who receive integrated care see fewer recurrences, better symptom management, and improved quality of life.

🚫 Myth: “Bloating = SIBO.”
🔍 Truth: Bloating is common—and non-specific. While SIBO/IMO can cause bloating, so can IBS, food intolerances (lactose/fructose), bile acid malabsorption, pancreatic insufficiency, gut motility disorders, pelvic floor dysfunction, and even stress via the gut-brain axis.

What this means:
Don’t jump to SIBO. Use symptoms to guide testing—not to replace it.

Context matters. Timing of symptoms, stool patterns, diet, meds, and surgical history help narrow the differential.

Test the right way. Hydrogen and methane breath testing differentiates small-bowel fermentation from other causes when performed with guideline-aligned prep, sampling intervals, and validated analytics.

How CDI helps:
Hydrogen + Methane analysis to avoid missed methane-dominant cases (IMO)

Guideline-aligned protocols (North American Consensus, ACG) with 15–20 min sampling over ~2.5–3 hrs

High-precision GC methods with CO₂ correction and proven sample stability

Clear, actionable reports your provider can use to tailor care

👉 Bottom line: Bloating ≠ automatic SIBO. Get evidence, not guesses.
