What's this test for?

This test is ideal if you're experiencing digestive discomfort, bloating, skin issues, or unexplained fatigue after eating and suspect pecans might be a trigger. It checks whether your immune system is reacting to pecan proteins, which can help you figure out if cutting this food out might ease your symptoms. Many people use this test as a starting point when they can't pinpoint which food is causing their discomfort.

What happens after I get my results?

Your results will be available in your account, with your IgG reaction level to pecans explained alongside the normal reference range. If your result comes back elevated, a practical next step is to remove pecans 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 if you test again in the future. If you notice severe reactions like swelling or trouble breathing after eating pecans, seek medical care right away since that may indicate a true allergy rather than a sensitivity.

Who should consider this test?

Anyone who regularly eats pecans or pecan-containing foods and deals with ongoing digestive issues, skin flare-ups, headaches, or fatigue without a clear cause should consider this test. It's also useful for people who've tried eliminating other foods without relief and want to narrow down the list of possible triggers. This test is not meant to replace emergency allergy testing for sudden, severe reactions.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach cramps, diarrhea or constipation, skin rashes or eczema, joint pain, headaches, and low energy that seem to show up hours after eating. These symptoms are often delayed, which makes it hard to connect them to a specific food without testing. If you've noticed a pattern around meals that include pecans or pecan-based products, this test can help confirm a possible link.

How can I naturally support food sensitivity symptoms?

If your results show a reaction to pecans, start by removing pecans and pecan oil from your diet for two to three weeks and track how you feel. Supporting your gut with foods like yogurt, fermented vegetables, and fiber-rich produce can help calm inflammation and improve digestion. Staying hydrated and reducing processed foods during this period can also make it easier to notice improvements in your symptoms.

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 your report is available in your account, so there's no need to call or follow up. This timeline allows the lab to run detailed antibody testing accurately.

What does high IgG to pecan mean?

A high result means your immune system has produced more antibodies against pecan proteins than expected, which some experts believe correlates with sensitivity symptoms after eating this food. This doesn't mean you have a life-threatening allergy — it's a different immune pathway than classic allergic reactions. Many people find that reducing or eliminating pecans for a few weeks helps ease symptoms like bloating or fatigue.

What causes a high IgG reaction to a specific food?

Frequent or repeated exposure to a food, an imbalanced gut lining that lets food particles interact more with your immune system, and individual immune sensitivity can all contribute to elevated IgG levels. Some people naturally react more to certain proteins, like those found in tree nuts such as pecans, without it being a true allergy. Diet variety and gut health both play a role in how your body responds over time.

How often should I retest?

If you eliminate pecans after a high result, retesting after 3 to 6 months can help you see whether your antibody levels have changed. Retesting is also useful if you reintroduce the food later and want to check your body's response again. There's no need to retest frequently unless you're actively adjusting your diet based on symptoms.

What should I do if my results are abnormal?

Start by removing pecans from your meals and reading labels carefully, since pecans can appear in baked goods, sauces, and snack mixes. Keep a simple food and symptom journal to track improvements over the following weeks. If symptoms persist despite eliminating the food, consider looking into other potential triggers or seek medical care if symptoms are severe.
