What's this test for?

This test is ideal if you're experiencing ongoing digestive troubles, skin flare-ups, bloating, headaches, or fatigue that seem to follow certain meals but you can't pinpoint the cause. It looks for delayed immune reactions to a wide range of common foods that may be contributing to your symptoms. Many people use this test to help figure out which foods to try eliminating from their diet.

What's included in this test?

This panel checks your immune response to a broad range of common foods across categories like dairy, grains, meats, vegetables, fruits, and spices. Each category matters because delayed food reactions can show up in very different ways, from skin issues to digestive discomfort to fatigue, so casting a wide net helps identify triggers you might not otherwise suspect.

What happens after I get my results?

Your results will show up in your account with each food listed along with its reaction level clearly explained, so you know exactly what falls in a normal versus elevated range. From there, a common next step is trying an elimination diet, removing the highest-reacting foods for a few weeks and tracking how you feel. You can download a standard lab report from your account at any time, and if you retest later, the trends feature lets you compare results over time to see if avoiding certain foods made a difference.

How can I naturally support digestive health while identifying food triggers?

Keeping a simple food and symptom journal alongside this test can help you connect the dots faster. Eating more whole, unprocessed foods, staying hydrated, and adding gut-friendly foods like plain yogurt or fermented vegetables can ease digestive stress while you sort out triggers. Reducing alcohol and highly processed snacks temporarily can also help calm symptoms so it's easier to notice patterns.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your secure online account, and you'll get a notification so you can log in and review everything as soon as it's available.

Who should consider this test?

This test is a good fit for anyone dealing with unexplained digestive issues, chronic bloating, skin breakouts, or low energy that seems tied to eating patterns. It's also useful if you've already tried cutting out obvious culprits like gluten or dairy without much improvement and want a broader look. People managing conditions like eczema or IBS-type symptoms often find this test helpful for narrowing down triggers.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach cramps, diarrhea or constipation, skin rashes or eczema flare-ups, brain fog, joint aches, and fatigue that seem to worsen after eating. If these symptoms show up hours or even a day after meals rather than immediately, that delayed pattern is exactly what this type of test is designed to investigate.

What does a high reaction level mean for a specific food?

A high reaction level means your immune system is producing more antibodies against that particular food than is typical, which some people associate with the symptoms they've been experiencing. It doesn't mean you're allergic in the traditional sense, but many people choose to reduce or eliminate that food for a few weeks to see if symptoms improve. Reintroducing it slowly afterward can help confirm whether it was actually a trigger.

What causes elevated reactions to certain foods?

Elevated reactions can develop from eating certain foods very frequently, having an imbalanced gut environment, or general digestive stress that makes your gut lining more permeable to food particles. Genetics and overall diet diversity can also play a role in which foods your body reacts to. This is why two people with similar diets can have very different results.

How often should I retest?

Many people retest after 3 to 6 months of adjusting their diet based on their first results, especially if they've eliminated and then reintroduced certain foods. Retesting can help confirm whether avoiding specific foods actually lowered your reaction levels. If your symptoms fully resolve and stay away, you may not need to retest again unless new symptoms appear.
