Who We Are

We live in a time of unprecedented change in healthcare and diagnostics. AllClear exists to get what’s already proven – and what’s coming – into practitioners hands faster and more affordably than the system does today. We identify, license, acquire and distribute advanced diagnostics emerging from bio venture engineering pipelines that have already been developed and validated.

Our beachhead is an at-home/mail-in BREATH test for highly prevalent chronic gut health issues like SIBO / IMO, Lactose Intolerance and more. Learn more about Why We Exist here

What We Do

We operate a CLIA lab in Boston. We provide convenient at-home/mail-in Hydrogen/Methane BREATH testing to uncover the root causes of high prevalence chronic gut issues of the small intestine including:

  • SIBO/IMO breath testing (we offer glucose or lactulose substrates)
  • Lactose intolerance breath testing
  • Fructose malabsorption breath testing
  • Sucrose intolerance breath testing

We deliver binary, clinically supported results to both practitioners and patients:

Want your practitioner to provide Gut Health Breath Testing? Practitioner Referral

in brief: gut health breath testing

The problem: millions live with unexplained gut symptoms because the standard test looks in the wrong part of the body — a four-year average path to diagnosis, and $111.8B a year in system-wide cost.

The blind spot: the conditions being missed are specific and treatable. Small Intestinal Bacterial Overgrowth (SIBO), Intestinal Methanogen Overgrowth (IMO), Lactose Intolerance, Fructose Malabsorption, and Sucrose Intolerance. A stool test cannot see any of them.

The opportunity: a proven small-intestine breath test that we are getting it into the hands of practitioners — wellness, functional, and longevity doctors — who are best positioned to use it, at scale.

The stakes: A missed small intestine problem can silently limit how well other treatments work — from hormone therapy to GLP-1 weight-loss drugs, which recent research links to nearly three times the rate of small intestine overgrowth.

Community: We do this bringing together a community of practitioners learning from other practitioners and clinical experts, not as a sales operation. That’s deliberate: doctors trust other doctors, not a lab’s sales pitch, and every clinical decision stays with the licensed provider treating the patient. It’s also simply the right way to do this responsibly.

Vision for Wellness, preventative health & Longevity

While focused initially on chronic gut health diagnostics, AllClear’s platform and strategy are designed for nimble, multispecialty growth. We are targeting future expansion into oncology, neurology, pharmacogenetics, stem cell, and other diagnostic fields. This diversified diagnostic portfolio offers practitioners considerable upside as bio-venture pipelines mature and new meaningful and actionable diagnostics gain regulatory approval and commercial viability.

Comprehensive Gastrointestinal Health

Many people suffer from digestive problems that can significantly affect their daily lives. Conditions like irritable bowel syndrome (IBS) and various food intolerances can cause discomfort and disrupt routines. Identifying the root cause of these symptoms is crucial for effective treatment. Small intestinal bacterial overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO) in particular, can be mistaken for other digestive disorders. Our comprehensive gastrointestinal health testing includes specialized tests to diagnose SIBO/IMO accurately.

Understanding Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO)

SIBO occurs when excessive bacteria populate the small intestine, an area that normally contains relatively low levels of bacteria. IMO is caused by an overgrowth of methane-producing microorganisms, known as methanogens, which may be present throughout the intestinal tract. Elevated methane levels are commonly associated with slowed intestinal transit and constipation-predominant symptoms.

Both conditions can develop as a result of underlying medical issues or prior treatments, including acid suppression therapy, antibiotic exposure, abdominal surgeries, motility disorders, autoimmune disease, and other gastrointestinal conditions. Without addressing contributing factors, symptoms may recur even after treatment. If SIBO or IMO is identified, patients should work closely with their healthcare provider to determine appropriate next steps and whether additional evaluation is warranted.

Symptoms and Diagnosis

Symptoms associated with SIBO and IMO often overlap with IBS and other gastrointestinal disorders. Common symptoms may include:
• Bloating and excessive gas
• Abdominal discomfort or cramping
• Heartburn or nausea
• Diarrhea and/or constipation
• Fatigue and generalized discomfort
• Headaches or skin changes in some individuals
• Reduced appetite or unintended weight changes related to malabsorption

Because symptoms are nonspecific, SIBO and IMO may go unrecognized without appropriate testing. Breath testing measures hydrogen and methane gas levels to support clinical evaluation and guide further care decisions in collaboration with a healthcare provider.

Treatment and Management

Treatment should always be directed and monitored by a qualified physician. Management may include targeted antibiotic therapy and additional interventions depending on the underlying cause, such as addressing motility issues or structural complications related to prior surgeries. Long-term management often focuses on reducing recurrence and supporting overall digestive health.

The Importance of Early Diagnosis

Earlier identification can help guide more timely intervention and reduce the risk of complications associated with prolonged malabsorption or unmanaged symptoms. Ongoing care should focus on addressing contributing factors to support durable symptom improvement.

Comprehensive Testing for Accurate Results

Our CLIA-certified, lab-verified breath testing delivers accurate, reliable results to support informed clinical decision-making. Convenient at-home collection options allow patients to complete testing comfortably while maintaining high laboratory standards for analysis and reporting.

Don’t Let Gut Health Issues Disrupt Your Life

Whether you are a clinician seeking efficient diagnostic insight or an individual pursuing clarity around persistent digestive symptoms, our comprehensive breath testing offers a reliable path forward. Trust AllClear Healthcare’s commitment to accuracy, compliance, and clinical quality to support better digestive health outcomes.

Talk with a healthcare provider to determine if breath testing is appropriate and take the next step toward improved gastrointestinal health.

Our Mission

AllClear Healthcare is paving the way for practitioner-based education, learning, and progress through continuing education, research, and a network of like-minded industry professionals and solutions.

AllClear Healthcare’s mission is to positively disrupt unmet needs within our underperforming healthcare system. We provide comprehensive, patient-focused and convenient testing options that give you rapid, accurate and affordable results – often in just minutes. We are scaling our digital, customer-centric platform to provide exceptional diagnostic solutions for a variety of newly emerging individual and public health needs.

Through our health diagnostics efforts, we have also had the opportunity to significantly contribute to the safety and productivity of our local and national business communities to keep communities, organizations, and businesses up and running safely, confidently, and productively.

AllClear Healthcare is committed to bringing the most accurate gastrointestinal and other health testing possible, including small intestinal bacterial overgrowth (SIBO)/ Intestinal Methanogen Overgrowth (IMO) breath testing and testing for diseases of carbohydrate metabolism.

AllClear Healthcare, a best-in-class testing company, was founded at the height of the pandemic to offer FDA-approved rapid, accurate, and affordable COVID-19 testing. Soon, we extended our respiratory testing offerings to include RSV, influenza A&B, and strep.

Collaborating with healthcare practitioners and patients, we found that the problem of slow and inefficient testing options exists in the diagnostics world for gastrointestinal illnesses as well.

Gastrointestinal issues are rampant. 35.4 million people visit their primary care doctor each year with gastrointestinal diseases as the primary diagnosis (1). Digestive issues are the 13th leading cause of disability-adjusted life year (DALY) (2).

Yet, SIBO/IMO diseases of carbohydrate metabolism, and other gastrointestinal issues go undiagnosed and under-diagnosed because of slow, inefficient, invasive, and expensive testing options (3).

Our main focus has expanded to offer fast, accurate, and affordable Hydrogen/Methane breath testing solutions for gastrointestinal issues — a much-missing piece in medicine. We now help practitioners get their patients treatment faster with At-home, Mail-in testing that is highly accurate and affordable for:

  • SIBO/IMO breath testing (we offer glucose or lactulose substrates)
  • Lactose intolerance breath testing
  • Fructose malabsorption breath testing
  • Sucrose intolerance breath testing

We believe these new testing protocols can help your practice improve efficiency and accelerate the time to better health by triaging patients rapidly and helping to reduce the cost of diagnostics for your patients.
