What's this test for?

This test is ideal if you're experiencing bloating, stomach pain, skin issues, or other unexplained discomfort after eating apples or apple-containing foods. It measures your immune system's IgG antibody response to apple proteins, which can point to a food sensitivity rather than a true allergy. Many people use this test to figure out if apples might be quietly contributing to ongoing digestive or skin symptoms.

How should I prepare for this test?

See the pre-collection instructions on your order confirmation.

What's included in this test?

This test focuses on a single, specific biomarker: IgG antibodies to apple. Measuring this antibody response matters because elevated IgG levels to a specific food can be a clue that your immune system is reacting to it, which some people connect to symptoms like bloating, fatigue, or skin flare-ups after eating that food.

What happens after I get my results?

Your results will be available in your account, with your IgG antibody level clearly explained alongside the normal reference range. If your level comes back elevated, a simple next step is to reduce or eliminate apples from your diet for a few weeks and see if your symptoms improve, then consider retesting later to track changes. A standard lab report is available to download from your account, and you can use the trends feature to monitor your results over time if you test again in the future.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once available, you'll be able to log into your account to view your IgG antibody level and what it means, and you can download the full lab report at any time.

Who should consider this test?

This test is a good fit for anyone who notices digestive discomfort, bloating, headaches, or skin issues after eating apples or apple-based products and wants to explore whether a food sensitivity could be involved. It's also useful for people who are already working through an elimination diet and want more data to guide which foods to reintroduce carefully. If you have a history of noticing symptoms tied to certain foods but haven't pinpointed the trigger, this test can help narrow things down.

What symptoms indicate I may need this test?

Common signs that prompt people to check for an apple sensitivity include bloating, gas, stomach cramps, diarrhea or constipation, skin rashes or eczema flare-ups, headaches, or fatigue that seems to follow eating apples or apple products. If these symptoms show up repeatedly after similar meals, a food-specific reaction may be worth investigating. Keeping a simple food and symptom diary alongside this test can help you connect the dots.

How can I naturally support digestive health if I have a food sensitivity?

If your results suggest a sensitivity to apples, try removing apples and apple-derived ingredients from your diet for two to four weeks and track how you feel. Support your gut with whole, minimally processed foods, plenty of water, and fermented foods like yogurt or sauerkraut, which can help maintain a healthy gut lining. Reintroduce apples slowly afterward to see if symptoms return, and consider spacing out how often you eat any food you react to rather than eliminating it forever.

What does a high IgG level to apple mean?

A high IgG level means your immune system has produced more antibodies in response to apple proteins, which some people associate with lingering digestive or skin symptoms after eating apples. It doesn't mean you're having a dangerous allergic reaction like swelling or trouble breathing — that would be a different type of immune response entirely. Instead, it's a signal worth exploring through a short trial elimination of apples to see if your symptoms ease up.

How often should I retest?

If you eliminate apples based on an elevated result, many people retest after 8-12 weeks to see whether their IgG level has changed alongside their symptoms. Retesting can also be useful once or twice a year if you're systematically working through different foods to understand your overall sensitivity pattern. There's no need to retest sooner unless your symptoms change significantly.
