What's this test for?

This test is ideal if you're experiencing bloating, stomach discomfort, skin issues, or other unexplained symptoms after eating potatoes or potato-containing foods. It measures your immune system's IgG antibody response to potato, which some people use as part of a broader look at possible food sensitivities. This can be a helpful starting point if you suspect certain foods may be linked to how you feel day to day.

What happens after I get my results?

Your results will show up in your account with your IgG level clearly marked against the normal reference range so you can see exactly where you fall. If your level is elevated, a practical next step is to try removing potato from your diet for a few weeks and note whether your symptoms improve, then consider retesting later to track changes. A downloadable lab report is available in your account anytime, and you can use the trends feature to watch how your results shift if you test again in the future.

Who should consider this test?

This test is a good fit for anyone who notices digestive upset, skin reactions, headaches, or fatigue that seem to follow eating potatoes or foods that contain potato. It can also be useful if you're trying to narrow down a list of foods that might be contributing to ongoing, hard-to-pin-down symptoms. People already exploring an elimination diet often use tests like this to help decide which foods to test first.

What symptoms indicate I may need this test?

Common signs people look into potato sensitivity include bloating, gas, stomach cramps, diarrhea or constipation, skin rashes, joint aches, or brain fog that shows up after eating potato-based foods. If these symptoms seem to come and go depending on what you've eaten recently, it may be worth checking your IgG response to potato. Keeping a simple food and symptom diary alongside this test can help you spot patterns more clearly.

How can I naturally support digestive comfort around suspected food triggers?

If you think potato might be bothering you, try cutting it out of your meals for two to three weeks and see if your symptoms ease up. Eating smaller, simpler meals, staying hydrated, and adding gut-friendly foods like plain yogurt or fermented vegetables can also support digestion while you experiment. Slowly reintroducing potato afterward, one small amount at a time, can help you see if it's really the cause.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your secure online account, where you can view, download, and revisit them whenever you need.

What does high potato IgG mean?

A higher IgG level simply means your immune system has produced more antibodies in response to potato proteins, which some people associate with food sensitivity. It doesn't necessarily mean you have a true allergy, since IgG antibodies can also show up after normal, frequent exposure to a food. Many people use an elevated result as a cue to try a short trial without potato and see how they feel.

What causes a high potato IgG result?

Eating potato regularly is one of the most common reasons for a higher IgG reading, since your immune system naturally responds to foods you eat often. Other factors like gut health, how well your digestive lining is functioning, and overall immune activity can also influence the result. It's less about the food being harmful and more about how your body has been reacting to it lately.

How often should I retest?

If you make a dietary change based on your results, retesting after 8-12 weeks can help you see whether your IgG level has shifted. For general tracking without symptoms, testing once or twice a year is usually enough. Using the trends feature in your account makes it easy to compare results over time.

What should I do if my results are abnormal?

Start by trying a temporary elimination of potato from your meals and tracking whether your symptoms change over a few weeks. Reintroduce it slowly afterward to see if symptoms return, which can help confirm whether potato is really a trigger for you. If your symptoms are severe or persistent regardless of diet changes, seek medical care to rule out other causes.
