What's this test for?

This test is ideal if you're experiencing digestive discomfort, bloating, headaches, skin issues, or fatigue after drinking tea. It checks whether your immune system is reacting to tea in a way that could be causing ongoing, low-grade symptoms. Many people don't connect these symptoms to something they drink daily, so this test helps clear up the mystery.

What's included in this test?

This test measures your IgG antibody response specifically to tea. IgG antibodies are part of your immune system, and when they're elevated against a specific food or drink, it can point to a delayed sensitivity rather than an immediate allergic reaction. Checking this single, targeted marker helps you pinpoint whether tea itself is contributing to your symptoms.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a normal versus elevated value means. If your result comes back elevated, a simple next step is to remove tea from your diet for a few weeks and see if your symptoms improve, then reintroduce it slowly to confirm. You can download a standard lab report from your account at any time, and if you retest later, the trends feature lets you track how your levels change over time.

How can I naturally support a tea sensitivity?

If your results suggest a sensitivity, the simplest approach is cutting back on or eliminating tea for a few weeks to see if symptoms ease up. Swapping in caffeine-free herbal infusions or plain water can help you stay hydrated without the trigger. Keeping a simple food and symptom journal can also help you notice patterns and confirm whether tea is really the culprit.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once they're posted to your account so you can log in and review them right away. If you don't see them after 7 days, check your account for updates or contact support.

Who should consider this test?

This test is a good fit if you regularly drink tea and notice recurring symptoms like bloating, headaches, skin flare-ups, or fatigue that you can't explain. It's also useful if you're trying to narrow down food and drink triggers as part of a broader elimination approach. People with chronic digestive complaints who haven't found clear answers may find this a helpful piece of the puzzle.

What symptoms indicate I may need this test?

Common signs include bloating, stomach cramps, diarrhea or constipation, skin rashes or eczema flare-ups, headaches, joint aches, and unexplained fatigue that seem to follow drinking tea. Because IgG reactions are delayed, symptoms might not show up until hours or even a day after exposure, which makes them easy to miss. If you notice a pattern between tea consumption and these symptoms, this test can help confirm it.

What does a high result mean?

A high IgG level to tea suggests your immune system is producing an elevated antibody response to it, which some people associate with sensitivity-related symptoms. It doesn't mean you're having a dangerous allergic reaction, but rather that your body may be reacting in a way that contributes to inflammation or discomfort. A practical next step is reducing tea intake and watching whether your symptoms improve over the following weeks.

What causes a high IgG response to tea?

Frequent, repeated exposure to a specific food or drink is one of the most common reasons IgG levels rise, since your immune system builds up antibodies over time with regular contact. Gut health also plays a role — if your digestive lining is more permeable than usual, proteins from tea may trigger more of an immune reaction. Genetics and overall immune sensitivity can also make some people more prone to elevated responses than others.

How often should I retest?

If you make dietary changes based on your results, retesting after 2 to 3 months is a reasonable timeframe to see whether your IgG levels have changed. If your first test comes back normal but symptoms continue, you might consider testing again in the future if new patterns emerge. Regular retesting isn't necessary unless you're actively tracking a dietary change or your symptoms shift.
