What's this test for?

This test is ideal if you're experiencing reactions after eating soy or soy-containing foods, like hives, stomach upset, swelling, or breathing trouble. It helps pinpoint whether soy glycinin, a specific soy protein, is triggering an allergic response in your body. This is especially useful if you've had unexplained reactions and want to narrow down the cause.

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 IgE level means for this specific soy protein. If your level is elevated, a practical next step is avoiding soy-containing foods and reading ingredient labels closely, then retesting later if you want to confirm changes. If a reaction is ever severe, such as difficulty breathing or swelling of the throat, seek emergency medical care right away. You can download the full lab report from your account anytime and track this result over time using the trends feature.

What symptoms indicate I may need this test?

Common signs include hives, itching, stomach cramps, nausea, or swelling of the lips and face after eating soy products like tofu, edamame, or soy milk. Some people also notice a runny nose, coughing, or trouble breathing shortly after exposure. If these symptoms happen consistently around soy consumption, this test can help confirm the connection.

How can I naturally support soy allergy symptoms?

The most effective approach is avoiding soy and reading food labels carefully, since soy hides in many processed foods, sauces, and packaged snacks. Keeping a food and symptom journal can help you notice patterns and avoid trigger foods more easily. Some people also find that reducing overall processed food intake lowers accidental soy exposure.

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 so you can view and download them as soon as they're available.

Who should consider this test?

Anyone who suspects soy is causing allergic reactions, especially after eating soy-based foods, is a good candidate for this test. It's also useful for people who've had a positive general soy allergy screen and want to confirm which soy protein is the specific trigger. Parents monitoring a child's food reactions may also find this test helpful.

What does high glycinin IgE mean?

A high result means your immune system has developed antibodies specifically against the glycinin protein in soy, indicating a true soy allergy rather than just sensitivity. This suggests your body reacts to soy exposure and that avoiding soy products may reduce your symptoms. The higher the number, the more strongly your immune system is reacting, though symptom severity doesn't always match the number exactly.

What causes high soy IgE levels?

High soy-specific IgE happens when your immune system mistakenly identifies the glycinin protein as harmful and creates antibodies against it. This immune response can develop at any age, even if you've eaten soy without problems before. Genetics, other existing allergies, and early life exposure patterns can all play a role in whether this sensitivity develops.

How often should I retest?

If you're actively avoiding soy, retesting once a year can help track whether your sensitivity is changing over time. If you're managing symptoms and want to see if avoidance strategies are working, retesting every 6 to 12 months is reasonable. There's no need to retest sooner than a few months, since antibody levels don't shift quickly.

What should I do if my results are abnormal?

Start by eliminating soy and soy-derived ingredients from your diet and monitoring whether your symptoms improve. Keep the downloadable lab report handy for reference, and use the trends feature to track changes if you retest later. If you experience severe symptoms like swelling or difficulty breathing after soy exposure, treat it as an emergency and seek immediate medical care.
