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.

Cost uncertainty shouldn’t be the reason a clinically useful breath test never gets ordered.

CDI’s coverage model is designed to keep financial conversations concrete:
✔️Accepts Medicare, Medicare Advantage, and Tricare with no balance billing
✔️Submits claims to all commercial insurers
✔️Uses a clearly defined maximum out‑of‑pocket cost per test—among the lowest in the industry—so patients know the ceiling before they say yes

For practices, that means you can frame breath testing as a predictable investment, not a financial unknown.

For patients, it means fewer surprise bills and fewer stalled workups because no one was sure what coverage would look like.

From a clinic’s point of view, at‑home testing only works if the lab partner actually supports your patients.

As Teri put it:
“Staff always returned patient's calls, answered questions, were very patient and professional.”

That kind of support matters. It means fewer families calling your front desk with basic kit questions and fewer tests abandoned because someone got stuck halfway through.

CDI backs its at‑home HMBT with live phone support, email assistance, and patient‑facing resources so your team doesn’t have to absorb every prep or logistics question.

In many practices, completion isn’t the real finish line for breath testing. Care action is.

The Breath Testing Done Right pathway treats “completion to care action” as its own step:
▪️Does your team know, in one place, which tests are complete and ready to review?
▪️Do reports make it obvious whether the pattern is supported or not, or do you have to reverse‑engineer it?
▪️Is there a clear plan for how quickly completed tests should lead to follow‑up visits or telehealth touchpoints?

When those answers are fuzzy, even a clinically sound and operationally efficient testing program can underperform. Completed tests quietly pile up without changing care.

Looking at this “last mile”, explicitly who owns it, how quickly it should happen, and how tools like MyGI Gateway and structured reports support it is one of the fastest ways to improve the real‑world value of HMBT.

10/28/2026

The hardest part of a breath testing program often isn’t getting kits out. It’s making sure completed tests reliably turn into care action.

CDI’s program is built around that “completion to care” link:
◽MyGI Gateway shows which tests are completed and ready for review
◽Reports flag patterns as supported or not supported rather than leaving you with just curves
◽Turnaround within 1 business day of sample receipt keeps results relevant to upcoming visits

That means fewer missed opportunities where a patient completed testing but never got a follow‑up decision, and fewer visits stalled because the result isn’t in front of the clinician.

If your team is good at ordering kits but less confident about what happens after they come back, this is where to look first.

10/26/2026

From a practice perspective, a breath test only matters if it turns into a clear next step, quickly.

Here’s how one GI group described working with CDI:
“Our team was impressed by how quickly results came back and how clearly they were laid out. We weren’t just getting numbers; we were getting patterns labeled as supported or not supported so we knew who needed treatment, who needed repeat testing, and who needed a different workup. It made follow‑up visits much more straightforward.”

Fast turnaround + clear interpretation means less time hunting for results and more time having concrete conversations with patients.

CDI designs its HMBT reports and workflows to support that: 1‑business‑day turnaround from sample receipt, supported/not supported patterning, and MyGI Gateway visibility so providers know when a test is ready to act on.

Live from NASPGHAN in San Diego.

If you’re here this week, come by the CDI booth to talk about pediatric breath testing that families can actually complete at home.

We’re here to dig into:
✔️Pediatric HMBT for SIBO, IMO, and carbohydrate malabsorption
✔️Age‑appropriate prep, clear instructions, and real support for families
✔️How MyGI Gateway helps peds teams see which kits are out, back, and resulted
✔️Emerging gut–brain conversations, including ADHD and chronic symptom overlap

If you’re thinking about how to make peds SIBO/IMO evaluation more practical for both families and clinics, we’d love to talk.

Parents of kids with ADHD often show up in GI clinic describing sleep issues, appetite swings, belly pain, bloating, or irregular stools and wondering how much is “gut” and how much is “brain.”

A recent Beyond the Gut discussion looks at ADHD and the peds gut–brain axis:
▪️How GI symptoms can compound attention, behavior, and school‑day functioning
▪️Where it makes sense to evaluate for SIBO, IMO, or carbohydrate malabsorption as part of the picture
▪️How to talk with families about gut and brain without overpromising or oversimplifying

Breath testing isn’t a cure for ADHD. But in selected kids with overlapping GI and attention symptoms, clarifying gut load can be a meaningful part of making school and home life more manageable.

If you’re at NASPGHAN thinking about how to integrate gut–brain conversations into peds GI and behavioral health, this is a good place to start.

Sending a family home with a pediatric breath test only works if they believe they can actually do it.

Here’s the kind of feedback CDI aims for from peds families:

“We were nervous about doing a test at home with our child, but the instructions were clear, support was available when we had questions, and shipping it back was easy. It ended up being much simpler than we expected.”

When families feel guided from the first instruction sheet to the final return label, they’re far more likely to complete testing on time and correctly. For peds GI teams, that means fewer stalled workups, fewer avoidable retests, and more visits grounded in objective data.

CDI’s pediatric HMBT is designed to create that experience: age‑appropriate instructions, family‑friendly prep, live support, and simple returns.

For many peds GI teams, the question isn’t “Should we test?”—it’s “Can families actually do a breath test at home with their child?”

CDI’s pediatric hydrogen and methane breath testing is designed with that reality in mind:
Non‑invasive, at‑home collection (no sedation, no lab chair)

A 6‑tube lactulose protocol tailored for smaller patients

Options for fructose, lactose, and sucrose testing when malabsorption is on the differential
Age‑appropriate instructions and family‑ready prep guidance

For NASPGHAN‑minded practices, that means you can evaluate peds SIBO/IMO and common carbohydrate malabsorption with a pathway that works for both kids and parents.
