CARBOHYDRATE BREATH TESTING FOR MALABSORPTION
The Trio-Smart malabsorption test is a breath test with an at-home sample collection kit that can indicate lactose, fructose, or sucrose intolerance.
The Trio-Smart malabsorption breath test is performed by measuring levels of hydrogen (H2) taken from a total of eight breath samples, six of those samples taken every 30 minutes, after lactose, fructose or sucrose consumption. The "expected" threshold of H2 is calculated by adding 20.00 ppm to the baseline (first viable sample prior to substrate ingestion). A rise in H2 levels of ≥20.00 ppm is supportive of malabsorption for the substrate ingested.
The Trio-Smart malabsorption breath test follows the recommendations provided by the North American Consensus on Hydrogen-Based Breath Testing in Gastrointestinal Disorders. The Trio-Smart malabsorption test is a validated Laboratory Developed Test (LDT) and is conducted in a CLIA-certified laboratory. Results are reported to you within seven business days after sample receipt.

SIBO AND MALABSORPTION BREATH TESTING
The North American Consensus states that you must rule out small intestinal bacterial overgrowth (SIBO) before concluding that there is carbohydrate malabsorption.
The Trio-Smart malabsorption test reports methane and hydrogen sulfide levels as well as hydrogen levels for malabsorption. If levels of methane and/or hydrogen sulfide are abnormal, then a breath test for SIBO is highly recommended to clarify.
The Trio-Smart device had a detection sensitivity of ±0.1 ppm. Conventional breath testing has a detection sensitivity of ±2.0 ppm.
