What's this test for?

This test is ideal if you're experiencing bloating, stomach cramps, skin flare-ups, headaches, or fatigue that seem to show up after eating certain foods. It looks for delayed immune reactions to a wide range of common foods that can be hard to pinpoint on your own. If you've tried elimination diets without clear answers, this panel can help narrow down which foods might be triggering your symptoms.

What's included in this test?

This panel checks your immune reaction to a broad list of common foods across categories like dairy, grains, meats, vegetables, fruits, and legumes. Testing across many food groups matters because sensitivities are often hidden — you might react to a food you eat daily without realizing it's connected to your symptoms. Covering this many foods at once gives you a fuller picture than testing just a handful of suspected triggers.

What happens after I get my results?

Your results will show up in your account with each food listed alongside its reaction level, so you can see exactly where you stand. From there, a simple next step is to temporarily remove the foods that show elevated reactions and watch whether your symptoms improve. You can download a standard lab report directly from your account for your records, and if you retest down the road, the trends feature lets you track how your reactions change over time as you adjust your diet.

How can I naturally support food sensitivity symptoms?

Cutting back on the foods that show elevated reactions for a few weeks, then slowly reintroducing them one at a time, is one of the most effective ways to spot patterns. Eating more whole, unprocessed foods and staying well hydrated can also help calm digestive irritation. Some people find that probiotic-rich foods like yogurt or fermented vegetables support gut comfort while working through dietary changes.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed. You'll get a notification once they're posted to your account, where you can view and download the full report.

Who should consider this test?

Anyone dealing with unexplained digestive issues, skin irritation, brain fog, or fatigue that seems tied to eating patterns may benefit from this test. It's also useful if you've already tried cutting out common allergens without much luck and want a broader look at possible food triggers. People managing chronic conditions like IBS or eczema often use this panel as part of figuring out dietary contributors.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach pain, diarrhea or constipation, skin rashes or eczema, joint aches, headaches, and unexplained fatigue after meals. If these symptoms show up hours or even a day after eating, that delayed pattern is often a clue that an immune-related food reaction could be involved. Keeping a food and symptom diary alongside this test can help connect the dots.

What does a high reaction level mean?

A high reaction level for a specific food means your immune system is producing an elevated response to it, which some people associate with digestive or skin symptoms. This doesn't mean it's a true allergy — it's a different kind of immune response that tends to be dose- and frequency-related. Reducing or rotating that food out of your diet for a few weeks is a reasonable first step to see if symptoms ease.

What causes elevated food reactions?

Elevated reactions can build up from eating the same foods very frequently, having a sensitive or irritated gut lining, or general immune system variability from person to person. Stress, illness, and gut imbalances can also make the gut more reactive to foods over time. There isn't one single cause, which is why testing a wide panel of foods is more useful than guessing.

How often should I retest?

Many people retest after 3 to 6 months of adjusting their diet based on their first results, to see how their reaction levels have changed. If you've eliminated and successfully reintroduced foods, retesting can confirm whether your body's response has settled down. Use the trends feature in your account to compare results side by side over time.
