Gastrointestinal Functional Testing

Gastrointestinal TestingGastrointestinal (GI) functional tests are used to determine the health of the gastrointestinal (GI) tract in patients of all ages. Both stool tests and saliva tests are used to screen for parasites, infections and other pathogens that may be found in the gastrointestinal tract. Additionally, stool gastrointestinal testing checks the gastrointestinal functions. Stool and saliva samples are collected and sent to the laboratory for testing. Stool samples check for a variety of food sensitivities and parasites such as –

If a patient has this parasite in the gastrointestinal tract, he or she may have cognitive disorders, stress intolerance, insomnia and depression. Additionally, brain cysts and muscle cysts are common in patients with this parasite.

Taenia Solium – Taenia Solium is a tapeworm often found in undercooked pork. A patient who has this tapeworm may experience blurry vision, headaches and seizures. The parasite may also cause abdominal discomfort, skeletal, muscle cyst, and brain cysts that may cause a decline in cognitive functions.

Entamoeba Histolytica – This intestinal and tissue parasite comes from fecal to oral contamination as the result of sexual contact. Patients suffering from this parasite may experience colon ulceration, abscesses of the lung or liver, diarrhea and perianal itching.

Trichinella Spiralis – This tissue worm happens when a patient has contact with wildlife or consuming improperly processed meat. Symptoms may include nausea, abdominal cramping and diarrhea. Other symptoms may include muscle pain, edema of the eyelids and fever.
