Get an accurate SIBO/IMO Test
Many people experience ongoing digestive discomfort, bloating, constipation, diarrhea, or nausea due to Small Intestinal Bacterial Overgrowth (SIBO) or Intestinal Methanogen Overgrowth (IMO), particularly following antibiotic use or in individuals with autoimmune conditions that affect gut health. Because symptoms often overlap with irritable bowel syndrome (IBS), these conditions are frequently misdiagnosed—delaying appropriate treatment.
Our at-home breath test measures both hydrogen and methane gas to help identify SIBO or IMO, giving you and your physician reliable data to guide treatment decisions with confidence. Both glucose and lactulose (diabetic-friendly) test options are available. Please allow approximately three hours to complete the test at home, then send the samples to us for rapid analysis and reporting.
Please allow 3 hours to take the test.

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.

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.

Updating my practice has been so simple with AllClear Healthcare tests

Dr. Frank
As a patient, homerun
“As a patient, I was worried this would be complicated, and nervous I wouldn’t be able to do this on my own at home. Everything was explained very clearly when I received the test kit and after sending my test back, I had my results in under 24 hours. My treatment is now tailored to my SIBO diagnosis.”
Ada
Wonderful team, extremely simple process
“Simple process, wonderful team, better gut health diagnostics, and so affordable for our patients.”
Dr. Sajid
We are proud to offer AllClear tests
“Our practice is proud to know we are offering the best there is for chronic gut health screening and diagnosis, and we are constantly striving to build deeper trust with our patients. Using AllClear Healthcare has been a great decision.”
Dr. Shane
Simple, safe alternative.
“The most direct – yet invasive, surgical, and expensive method of evaluating for SIBO is an upper endoscopy with small intestinal fluid aspiration. However, breath testing is overall the preferred diagnostic method for SIBO. Breath testing is safe, simple, and noninvasive. AllClear Healthcare provides affordable, easy to use, and accurate results fast. Their tagline explains it clearly… modern practitioner diagnostics, better patient health.”
Dr. Marie
Improved my practice and patient outcomes
“Breath testing is the most widely utilized modality to diagnose small intestinal bac-terial overgrowth (SIBO) and trusted by Physicians and patients.”
Dr. Hugh
As smooth as could be
“Honestly the experience went as smooth as could be. We had a little panic at 7:30am, booked an appointment for 9, and got results by 9:15 and I was off to work. The form on the app took minutes to fill out and there were no problems at all. The employee that helped us out yesterday, Thomas, was great as well. He even called me with the results.”
Dante
I’m sold.
“I was unsure about how easy this test would be for me to explain to patients, my days are packed tight, and I didn’t want to add burden onto staff, but the directions are incredibly simple, and I have yet to have a patient who has had an issue with this test.”
Dr. Ivette
