Intolerance Is Common and Often Overlooked

Delayed Reactions, Finally Made Visible

One in four US adults reports food intolerances, yet these reactions are often mistaken for allergies or dismissed as just digestive issues. Unlike immediate allergies, IgG responses can be delayed by hours or days, which makes them hard to spot and easy to blame on the wrong food.

This test measures IgG antibody responses to 286 food and drink items, with results reported across Class 1 to 4 reactions. It is analyzed in a CLIA-certified lab using gold standard macroarray technology, and gives clearer insight than elimination diets alone.

The sample is a simple finger-prick you collect at home, with results in 5 to 10 working days.

The Slow-Burn Symptoms

Signs a Food May Not Agree With You

Because IgG reactions are delayed, the culprit is rarely the last thing you ate. If these low-grade symptoms keep hanging around, testing can connect the dots.

Bloating After Meals

The most common intolerance complaint. The report shows which of the 286 items produced your strongest IgG responses so you know where to start.

Persistent Fatigue

Low-grade immune responses to everyday foods can quietly drain energy. Delayed reactions make the cause almost impossible to spot without testing.

Brain Fog

Trouble focusing hours after eating can be food related. Testing helps you connect symptoms to specific items instead of guessing.

Skin Irritation

Intolerance can show up on your skin as dullness, dryness, or breakouts. Identifying trigger foods gives your skin a chance to settle.

Joint Aches

Ongoing low-grade inflammation is one way delayed food reactions can present. The Class 1 to 4 grading shows which foods matter most.

Digestive Ups & Downs

Cramps, irregularity, and discomfort that come and go often follow a delayed pattern. The report brings that pattern into focus.

Simple Sample, Serious Data

How the Intolerance Test Works

Collect a finger-prick blood sample at home, send it to the CLIA-certified lab, and receive your report within 5 to 10 working days. Every one of the 286 items is graded from Class 1 to Class 4 so you can see exactly which foods to watch.

What the Test Covers

286 food and drink items across every corner of your diet:

  • Vegetables, fruits, and superfoods
  • Dairy, eggs, and milk proteins
  • Meat, fish, and seafood
  • Grains, seeds, nuts, beans, and peas
  • Spices, fungi, and yeasts
  • Coffee, tea, sugars, and sweeteners
  • Additives and novel ingredients

Smarter Than an Elimination Diet

Elimination diets mean months of trial and error, cutting foods one at a time and hoping you picked the right one. Testing screens all 286 items at once and shows which ones produced the strongest IgG responses, reported across Class 1 to 4.

Our team helps you turn the report into a practical eating plan, and can pair it with gut testing or medical weight loss support when it makes sense. Results are an insight tool to guide decisions, not a medical diagnosis.

Frequently Asked Questions

Get answers to the most common questions about the Food & Drink Intolerance Test, from what IgG means to how to use your results.

How is intolerance different from allergy?

Allergies involve IgE antibodies and appear within minutes. Intolerances involve IgG antibodies and can take hours or days to show symptoms, which is why they are so hard to identify without testing. This test measures IgG. For allergies, see our 176 Allergy Test.

Why not just do an elimination diet?

Elimination diets test one food at a time and can take months. This panel screens 286 items in one pass and grades each from Class 1 to 4, giving you a clear starting list in under two weeks.

How do I take the test?

With a simple finger-prick blood sample collected at home. The kit ships to a CLIA-certified lab that uses gold standard macroarray technology, and results arrive in 5 to 10 working days.

What do Class 1 to 4 reactions mean?

Each item is graded by the strength of your IgG response. Class 1 is a mild response and Class 4 is the strongest. Higher classes are the foods most worth adjusting first.

Is this a medical diagnosis?

No. The report is laboratory-based insight into your IgG responses, designed to guide food choices. For significant or worsening symptoms, review your results with a healthcare professional.
