Test information

The co-program is a study of feces (feces, excrement, stool), analysis of its physical and chemical properties, as well as various components and inclusions of various origins. It is part of the diagnostic study of the digestive organs and the function of the gastrointestinal tract. Fecal is the end product of food digestion in the gastrointestinal tract under the influence of digestive enzymes, bile, gastric juice and the vital activity of intestinal bacteria.

The composition of feces is water, the content of which is normally 70-80%, and dry residue. In turn, the dry residue consists of 50% of living bacteria and 50% of the remains of undigested food. Even within the norm, the composition of feces is largely unstable. It largely depends on nutrition and fluid intake. To an even greater extent, the composition of feces varies with different diseases.

The amount of certain components in the stool changes with pathology or impaired function of the digestive organs, although abnormalities in the work of other body systems can also significantly affect the activity of the gastrointestinal tract, and therefore the composition of feces. The nature of changes in different types of diseases is extremely diverse.

The following groups of violations of the composition of feces can be distinguished: a change in the number of components that are normally contained in the stool, undigested and / or undigested food residues, biological elements and substances released from the body into the intestinal lumen, various substances that are formed in the intestinal lumen from metabolic products, tissues and cells of the body, microorganisms, foreign inclusions of biological and other origin.
