SIBO/IMO Pediatric Lactulose Breath Test vs Array 4 By Cyrex Laboratories
The SIBO/IMO Pediatric Lactulose Breath Test and Array 4, both developed by Cyrex Laboratories, are sophisticated diagnostic tools used for evaluating gastrointestinal health in children. Understanding the principles, procedures, and effectiveness of these tests is essential for healthcare professionals and parents seeking accurate and reliable diagnostic information.
Understanding SIBO/IMO Pediatric Lactulose Breath Test
The Science Behind the Lactulose Breath Test
The SIBO/IMO Pediatric Lactulose Breath Test is based on the scientific understanding that small intestinal bacterial overgrowth (SIBO) and intestinal mucosal impairment (IMO) can lead to a myriad of gastrointestinal symptoms in children. This non-invasive test analyzes the levels of hydrogen and methane gas produced by bacteria in the small intestine, which can indicate the presence of SIBO.
Small intestinal bacterial overgrowth (SIBO) occurs when there is an abnormal increase in the number and/or types of bacteria in the small intestine. This overgrowth can interfere with the normal digestion and absorption of nutrients, leading to symptoms such as bloating, abdominal pain, diarrhea, and malnutrition. Intestinal mucosal impairment (IMO) refers to damage or dysfunction of the intestinal lining, which can result from various factors such as infections, inflammation, or autoimmune conditions. Impaired intestinal mucosa can disrupt the barrier function of the intestine, allowing bacteria to proliferate and cause further digestive disturbances.
Procedure and Interpretation of the Test
The test starts with the child fasting overnight to ensure accurate results. They then consume a specified amount of lactulose, a non-absorbable sugar solution. Lactulose is chosen as the substrate for this test because it is not digested or absorbed in the small intestine, but instead reaches the colon where it is fermented by bacteria. Bacteria in the small intestine ferment the lactulose, resulting in the production of hydrogen and/or methane gas. Breath samples are collected at regular intervals, typically every 15 minutes, for up to three hours. These samples are then analyzed to determine the levels of gas present.
During the test, it is important for the child to remain calm and relaxed, as stress and physical activity can affect the results. The healthcare provider will provide clear instructions on how to breathe into the collection device and ensure that the samples are properly collected and labeled for accurate analysis.
Interpretation of the test involves comparing the collected gas concentrations to established reference ranges. Elevated levels of hydrogen and/or methane can indicate the presence of SIBO. However, it is important to note that a comprehensive interpretation should consider symptoms, medical history, and clinical judgment. The healthcare provider will take into account the child's specific symptoms, medical history, and other diagnostic tests to make an accurate diagnosis and develop an appropriate treatment plan.
In some cases, a lactulose breath test may also be used to monitor the effectiveness of treatment for SIBO. By repeating the test after treatment, healthcare providers can assess whether the bacterial overgrowth has been successfully eradicated or if further intervention is necessary.
Potential Risks and Complications
The SIBO/IMO Pediatric Lactulose Breath Test is considered safe and well-tolerated by most children. However, as with any medical procedure, there are potential risks and complications to be aware of. These include mild discomfort, bloating, or nausea during the test. These symptoms are usually temporary and resolve once the test is completed. It is essential to discuss any concerns with a healthcare provider prior to undergoing the test.
In rare cases, a child may have an allergic reaction to lactulose or experience more severe complications such as vomiting, severe abdominal pain, or difficulty breathing. If any of these symptoms occur during or after the test, immediate medical attention should be sought.
It is important to note that the SIBO/IMO Pediatric Lactulose Breath Test should be performed under the supervision of a qualified healthcare professional who has experience in diagnosing and treating gastrointestinal disorders in children. The healthcare provider will ensure that the test is performed safely and accurately, and will guide the child and their family through the entire process, from preparation to interpretation of the results.
An Overview of Array 4 By Cyrex Laboratories

These markers are associated with gut permeability and immune dysregulation, allowing for targeted treatment strategies.
Array 4 goes beyond a simple assessment of gut health. It delves deep into the intricacies of the gastrointestinal system, highlighting the complex interactions between the gut lining and the immune system. By measuring the levels of specific antibodies, Array 4 offers a comprehensive analysis of the gut's response to various substances.
For example, zonulin is a protein that regulates the tight junctions between cells in the gut lining. Elevated levels of zonulin can indicate increased gut permeability, which may contribute to the development of autoimmune diseases. Array 4 can detect these elevated levels, providing crucial information for healthcare professionals to develop targeted treatment plans.
Similarly, the presence of occludin antibodies in the blood may suggest a compromised intestinal barrier. Occludin is another protein involved in maintaining the integrity of the gut lining. When antibodies against occludin are detected, it indicates potential damage to the gut barrier, which can lead to increased inflammation and immune dysregulation.
Actomyosin, LPS, and lipopolysaccharide-units (LPS-U) are additional markers measured by Array 4. Actomyosin is a protein found in the gut lining, and elevated levels may indicate increased gut permeability. LPS is a toxin produced by certain bacteria, and its presence in the blood can signal an immune response to bacterial overgrowth in the gut. Lipopolysaccharide-units (LPS-U) are the individual components of LPS, and their measurement helps to further assess gut health and immune reactivity.
