The Stool Chemistry test can provide important information regarding the efficiency of digestion and absorption can be gleaned from the measurement of the fecal levels of elastase (pancreatic exocrine sufficiency), fat, muscle and vegetable fibers, and carbohydrates. Inflammation can significantly increase intestinal permeability and compromise assimilation of nutrients. The extent of inflammation, whether caused by pathogens or inflammatory bowel disease (IBD), can be assessed and monitored by examination of the levels of biomarkers such as lysozyme, lactoferrin, white blood cells and mucus. These markers can be used to differentiate between inflammation associated with potentially life-threatening inflammatory bowel disease (IBD), which requires lifelong treatment, and less severe inflammation that can be associated with irritable bowel syndrome (IBS) which is frequently due to the presence of enteroinvasive pathogens. Lactoferrin is only markedly elevated prior to and during the active phases of IBD, but not with IBS. Monitoring fecal lactoferrin levels in patients with IBD can therefore facilitate timely treatment of IBD, and the test can be ordered separately. Since the vast majority of secretory IgA (sIgA) is normally present in the GI tract, where it prevents binding of pathogens and antigens to the mucosal membrane, it is essential to know the status of sIgA in the gut. sIgA is the only bona fide marker of humoral immune status in the GI tract.

Cornerstones of good health include proper digestion of food,
assimilation of nutrients, exclusion of pathogens and timely elimination
of waste. To obtain benefits from food that is consumed, nutrients must
be appropriately digested and then efficiently absorbed into portal
circulation. Microbes, larger-sized particles of fiber, and undigested
foodstuffs should remain within the intestinal lumen. Poor digestion and
malabsorption of vital nutrients can contribute to degenerative
diseases, compromised immune status and nutritional deficiencies.
Impairment of the highly specific nutrient uptake processes, or
compromised GI barrier function, as in "leaky gut syndrome," can result
from a number of causes including:
Low gastric acid production
Food allergen impact on bowel absorptive surfaces
Bacterial overgrowth or imbalances (dysbiosis)
Pathogenic bacteria, yeast or parasites and related toxic irritants
The use of NSAIDs and antibiotics
Impairment of intestinal functions can contribute to the development of food allergies, systemic illnesses, autoimmune disease, and toxic overload from substances that are usually kept in the confines of the bowel for elimination. Efficient remediation of GI dysfunctions incorporates a comprehensive guided approach that should include consideration of elimination of pathogens and exposure to irritants, supplementation of hydrochloric acid, pancreatic enzymes and pre- and probiotics, and repair of the mucosal barrier.
