At-home blood spot collection | Measures immune reactivity to 176 foods + gut barrier integrity
The FIT 176 + Gut Barrier Panel is a comprehensive food inflammation and gut permeability assessment designed to identify immune-mediated food reactivity and evaluate the integrity of the intestinal lining. This panel analyzes IgG and immune complex (C3d) reactions to 176 foods, additives, and antigens, alongside markers of intestinal permeability, commonly known as “leaky gut.” Unlike standard food sensitivity tests, this panel combines delayed hypersensitivity (IgG) with inflammatory complement activation (C3d), offering greater clinical accuracy when identifying foods that may be driving chronic inflammation or immune overload. It also measures biomarkers such as Zonulin, Occludin, Actomyosin, and Lipopolysaccharides (LPS) to assess gut barrier function.
Biomarkers Assessed:
176 foods and additives, including:
Dairy, gluten, eggs, nuts, seeds, legumes, fruits, vegetables, meats, seafood
Natural flavors, preservatives, colorings (e.g., BHA, Red #40, MSG, saccharin)
Candida spp., polysorbate 80, lipopolysaccharides
Gut barrier markers:
Zonulin
Occludin
Actomyosin
LPS (Lipopolysaccharides)
Who This Test Is For:
This test is ideal for individuals experiencing:
Digestive symptoms (bloating, gas, irregularity, reactivity to foods)
Skin flares (eczema, hives, acne)
Fatigue, brain fog, or low energy
Autoimmune symptoms or chronic inflammation
Joint discomfort or muscle stiffness
Histamine intolerance or mast cell sensitivity
Food elimination success without clarity on long-term triggers
Plateaus in progress despite dietary/lifestyle changes
Suspected leaky gut or gut barrier compromise
It’s especially useful for those who have previously completed elimination diets or want objective insight before reintroducing foods.
