Intestinal Barrier Screen
You are what you ABSORB!
You can have the greatest diet of all time, but if your digestive system is not up to snuff, forget about it!!!
More than 60 million Americans suffer from some type of digestive disorder. Signs and symptoms include:
- Excessive belching & gas
- Constipation & Diarrhea
- Depression & Anxiety
- Brain fog
- Abdominal pain & bloating
- Heartburn/Acid Reflux
- Sweet cravings (especially at night)
- Night sweats
Underground Wellness is equipped with several test kits to help us find the root cause of your digestive issues.
Test Kit 304: Intestinal Barrier Screen (saliva)
The gold standard for measuring your inner environment. With a single saliva sample this test kit measures:
- Secretory IgA (a.k.a. The Immune System)
- Bacterial Overgrowth
- Yeast Overgrowth
- Antibodies to common dietary proteins (egg, cow’s milk, corn, wheat, soy)
- Leaky Gut Syndrome
Your Intestinal Barrier results will reveal the ecology of your gut. For example:
- Elevated secretory IgA may indicate the presence of an undiagnosed parasitic or bacterial infection (such as H. Pylori)
- Low secretory IgA indicates a compromised immune system
- Elevated dietary protein antibodies indicate the presence of multiple food sensitivies and gut permeability
