About the markers on the Gastrointestinal panel


A reliable marker for production of digestive enzymes from the pancreas

Intestinal Lysozyme and Intestinal Alpha Anti-Chymotrypsin

Stool Secretory IgA

Secretory IgA is a marker of immune system function in the digestive tract. It may be elevated in patients who are having a response to food allergies, or microbes in GI system. Very low secretory IgA is common and indicates stress, dysbiosis (imbalance in gut flora) and immune system defects (such as secretory IgA deficiency),

Stool culture for yeast and bacteria pathogens

Will test for candida and other non-candida yeasts. Will culture for bad bacteria such as Klebsiella, Proteus, Citrobacter, and pathogenic e. coli, beta hemolytic strep, Campylobacter, Pseudomonas, and Bacillus

Ova and Parasites

Microscopic examination for parasites such as Blastocystis hominis and amoebas

Digestive symptoms of parasites include:

Parasites may present with other symptoms as well: fatigue, allergies, depression, headaches, muscle aches, respiratory symptoms, joint pain, fever and weight loss.

Saliva testing for parasite antibodies

Testing method is IgA antibodies by ELISA

Toxoplasma gondii:

Transmission: under cooked meats and contaminated food consumption. Exposure to cat feces.

Findings: Persistent brain cysts leading to behavioral, cognitive and memory disorders; muscle cysts, depression, insomnia, reduced stress intolerance.

Pork Tapeworm (T. Solium)

Transmission: under cooked pork

Findings: abdominal discomfort, brain cysts leading to cognitive decline, headaches and seizures, skeletal muscle cysts, blurry vision

Entamoeba histolytica

Transmission: Fecal - oral contamination; household

Findings: Episodic diarrhea, perianal itch, causing colon ulceration. Locally invasive causing liver and lung abscesses

Trichinella spiralis

Transmission: wildlife contact, eating improperly processed meat or eating food contaminated with such meat.

Findings: abdominal cramping, nausea, diarrhea, muscle soreness and pain, leading to fibromyalgia, edema of the upper eye lids, fever

Roundworm (ascaris lumbricoides)

Transmission: Fecal-oral; contaminated water, fruits/vegetables

Food Intolerance Testing

Uses saliva Secretory IgA to detect inherited food intolerances to:

People who are predisposed react to these common antigens often experience intestinal inflammation after eating offending foods. Subsequently, the intestinal mucosa releases Secretory IgA to neutralize the antigens. SIgA testing, unlike IgG, allow the detection of mild, subclinical, and latent intolerance cases.
