What's this test for?

This test is ideal if you're experiencing symptoms like hives, itching, stomach upset, or breathing trouble after eating soy or soy-based foods. Soybeans are found in many processed foods, so reactions aren't always obvious right away. This test helps you figure out if your immune system is reacting to soy protein specifically.

What's included in this test?

This test measures one specific marker: soybean-specific IgE antibodies. This single marker matters because it shows whether your immune system has developed a sensitization response to soy protein, which is the first step in identifying a possible food allergy.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a positive or negative IgE result means. If your result is positive, a practical next step is to start reading food labels closely and try eliminating soy to see if symptoms improve, while keeping an eye out for severe reactions that need immediate medical care. You can download the standard lab report right from your account at any time. If you get tested again in the future, the trends feature lets you track changes in your soy sensitivity over time.

What symptoms indicate I may need this test?

Common signs include hives or itchy skin, swelling of the lips or throat, stomach cramps, nausea, or digestive upset after eating soy products like tofu, edamame, or soy milk. Some people also notice sneezing, a runny nose, or mild breathing difficulty. If symptoms happen shortly after eating soy-containing meals on a regular basis, this test can help confirm whether soy is the trigger.

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 guess or call in to check status.

Who should consider this test?

Anyone who suspects soy is causing them digestive issues, skin reactions, or breathing symptoms should consider this test. It's also useful for parents wondering if soy is behind a child's recurring reactions, or for people who eat a lot of soy-based or plant-protein foods and want to rule out sensitization before symptoms get worse.

How can I naturally support a soy sensitivity?

If your results come back positive, start by avoiding obvious soy products like tofu, soy milk, and edamame, and check labels for hidden soy ingredients like soy lecithin or textured vegetable protein. Swapping in other protein sources such as chicken, eggs, or legumes like chickpeas can help fill the gap. Keeping a simple food and symptom diary can help you spot patterns and confirm improvement once soy is reduced.

What does a high soybean IgE result mean?

A high or positive result means your immune system has produced antibodies against soy protein, indicating sensitization. This doesn't automatically mean you'll have a severe allergic reaction every time you eat soy, but it does raise the chance that soy exposure could trigger symptoms. Pay attention to how your body reacts after soy exposure and consider limiting it if you notice symptoms.

What causes a positive soybean IgE result?

A positive result happens when your immune system mistakenly identifies proteins in soybeans as a threat and builds antibodies against them, usually after repeated exposure over time. This can develop at any age, though it's more common in people with other food allergies or a family history of allergies. Genetics and early diet exposure can both play a role.

How often should I retest?

If you've changed your diet to avoid soy and want to see if sensitization has decreased, retesting after 6-12 months is a reasonable timeframe. If symptoms change significantly or you're reintroducing soy into your diet, retesting sooner can help confirm whether it's safe to do so. Using the trends feature makes it easy to compare results side by side.
