Gastrointestinal Testing

While many things can be done with diet, testing is available, when necessary.

Hydrogen Breath Test for Small Intestinal Bowel Overgrowth (SIBO):

Breath testing measures the hydrogen (H)  gas produced by bacteria in the small intestine that has diffused into the blood, then lungs, for expiration.  Hydrogen is a gas produced by bacteria, not by humans.  The gas is graphed over 2 or 3 hours & compared to baseline.  Patients drink a sugar solution of glucose or lactulose after a 1 or 2 day preparatory diet.  The diet removes much of the food that would feed the bacteria, allowing for a clear reaction to the sugar drink.

Microbial Stool Analysis

This targeted stool test offers the ability to detect and identify bacteria, yeast (and optionally parasites), as well as providing valuable assessment of gut microbiota. Options include traditional culture techniques or the more advanced polymerase chain reaction methodology.

Potentially pathogenic bacteria that have been cultured can be tested against medications and supplements – helping to address identified imbalance with appropriate pharmacological or botanical treatments.

Comprehensive Stool Analysis

The Comprehensive Digestive Stool Analysis offers a comprehensive look at the overall health of the gastrointestinal (GI) tract including:

  • Digestion/Absorption Markers
  • Gut Metabolic Markers
  • Gut Microbiology Markers

Intestinal Permeability Assessment

Intestinal Permeability testing is a noninvasive gastrointestinal test assessment of small intestinal absorption and barrier function in the bowel. The small intestine functions as a digestive/absorptive organ for nutrients as well as an immune and mechanical barrier against excessive absorption of bacteria, food antigens, and other macromolecules.
