Why patients choose this test.
You eat clean, avoid the obvious stuff, and still feel bloated, foggy, or achy. Often the foods making you feel worst are ones most people consider healthy — eggs, almonds, spinach, yogurt, salmon. The Food Sensitivity Test is a CLIA-certified blood panel measuring IgG and IgA antibody responses to 96 commonly consumed foods.
Unlike IgE allergy tests (which catch immediate, severe reactions), this catches the delayed, low-grade reactions behind chronic bloating, fatigue, brain fog, headaches, joint pain, skin breakouts, and stubborn weight. You get a clear hierarchy of what to remove, rotate, and keep — and a provider to guide reintroduction.
What it measures.
A CLIA-certified blood test measuring IgG and IgA antibody responses to 96 commonly consumed foods, identifying the delayed-type reactions traditional allergy testing misses. Foods tested include:
- Dairy — cow's milk, goat's milk, casein, whey, common cheeses
- Grains — wheat, gluten, rye, barley, oats, rice, corn
- Eggs — whites and yolks tested separately
- Nuts and seeds — almond, walnut, cashew, peanut, sesame, and more
- Animal proteins — chicken, beef, pork, turkey, lamb, common fish
- Fruits and vegetables — common reactive and rotation foods
- Legumes, herbs, and spices
Both IgG and IgA are measured for the most complete delayed-reaction profile.
Who it's for.
Consider the Food Sensitivity Test if you have any of the following — especially when symptoms appear hours or days after eating:
- Bloating, gas, indigestion, or abdominal discomfort
- Brain fog, low energy, or post-meal sluggishness
- Headaches or migraines that may be food-triggered
- Skin issues — acne, eczema, rashes, redness
- Joint pain, stiffness, or muscle aches without a clear cause
- Sinus congestion, post-nasal drip, or asthma-like symptoms
- Mood swings, anxiety, or irritability
- Weight that won't shift despite a clean diet
You're a particularly strong candidate if you've already tried elimination diets and felt better but couldn't pinpoint exactly which foods were the culprits.
From booking to results.
- Booking — reserve online and our team confirms your appointment.
- At your appointment — a 10–15 minute blood draw at our Morristown or Colts Neck, NJ location, or via mobile draw within our service areas.
- Results — typically available within 7–10 business days as a color-coded report grading foods by low, moderate, and high reactivity.
- Consultation — a True Heal Wellness provider prioritizes which foods to remove first, designs an elimination phase (typically 6–12 weeks), and guides structured reintroduction so you can identify true triggers and expand your diet again.
Preparation: no fasting required. Keep eating your normal diet beforehand — antibody reactions are only measurable for foods you've actually been consuming.
