What's this test for?

This test is ideal if you're experiencing bloating, stomach pain, skin flare-ups, or other unexplained discomfort after eating and suspect tomatoes might be a trigger. It measures your immune system's IgG antibody response to tomato proteins, which some people use as a clue when trying to figure out food-related sensitivities. It's a helpful starting point if you've noticed a pattern between eating tomatoes and feeling unwell.

How should I prepare for this test?

How can I naturally support digestion if I suspect a tomato sensitivity? Keeping a simple food and symptom journal for a week or two before testing can help you connect the dots between what you eat and how you feel. Eating a normal diet that includes tomatoes in the days leading up to the test (rather than avoiding them) helps ensure the results reflect your typical immune response. Staying hydrated and getting consistent sleep can also support your body's overall digestive function.

What's included in this test?

This is a single-marker test that measures IgG antibodies specifically related to tomato. This matters because IgG responses can sometimes be linked to delayed food reactions, which are trickier to notice than immediate allergic reactions since symptoms may show up hours or even a day later.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus elevated IgG level means for tomato specifically. If your level comes back high, a simple next step is trying a short elimination period where you avoid tomatoes and tomato-based products, then reintroducing them slowly to see how you feel. You can download a standard lab report from your account at any time, and if you retest in the future, the trends feature lets you track how your antibody levels change over time.

When will I get my results?

Lab results for this tomato IgG test are typically ready within about 7 days of your sample being processed. You'll get a notification when your results are posted to your account, so there's no need to check back constantly.

Who should consider this test?

Anyone who notices recurring digestive issues, skin reactions, or general discomfort after eating tomatoes or tomato-containing foods (like sauces, salsas, or soups) might consider this test. It can also be useful for people already exploring a broader elimination diet and want data to help narrow down specific trigger foods.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach cramps, diarrhea, skin rashes or hives, headaches, or fatigue that seem to show up after eating tomatoes or tomato-based products. Because IgG reactions tend to be delayed, symptoms might not appear until several hours or even a day after eating, which can make the connection harder to spot without testing or careful tracking.

What does high tomato IgG mean?

A high result suggests your immune system is producing more antibodies against tomato proteins than typical, which some people associate with sensitivity-type symptoms after eating tomatoes. This doesn't necessarily mean a dangerous allergy, but it can be a useful clue if you're trying to identify what's causing ongoing discomfort. A practical next step is reducing tomato intake for a few weeks and noting whether your symptoms improve.

What causes high tomato IgG?

Elevated IgG levels to a specific food like tomato are often linked to frequent or repeated exposure to that food, since your immune system responds based on what you regularly eat. Some researchers also think gut health and how well your digestive lining handles certain proteins can play a role. Because IgG testing interpretation is still debated, it's best used alongside symptom tracking rather than as a standalone diagnosis.

How often should I retest?

If you make dietary changes based on your first result, retesting after 8-12 weeks can help you see whether your antibody levels have shifted along with your symptoms. Otherwise, retesting once or twice a year is reasonable if you're continuing to monitor food sensitivities as part of your general wellness routine.
