What's this test for?

This test is ideal if you're experiencing itching, hives, swelling, stomach upset, or breathing trouble after eating foods that contain sesame seeds. It checks whether your immune system has developed a specific antibody response to sesame, which is a common trigger for food allergy reactions. It's also useful if you suspect a sesame allergy but haven't been able to pin down the exact cause of your symptoms.

What's included in this test?

This test measures one specific marker: IgE antibodies targeted to sesame seed proteins. IgE antibodies are what your immune system produces when it mistakenly identifies a food as harmful, and measuring this particular one helps confirm whether sesame is a likely trigger for your symptoms.

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 simple next step is to avoid sesame seeds and foods made with sesame or tahini while paying close attention to how your body reacts when it's reintroduced. You can download a standard lab report directly from your account, and if you get tested again in the future, the trends feature lets you track changes in your sensitization over time.

What symptoms indicate I may need this test?

Common signs include hives, itching, swelling of the lips or throat, stomach cramps, nausea, or trouble breathing shortly after eating sesame seeds, tahini, hummus, or foods made with sesame oil or flour. Some people also notice a runny nose or itchy eyes. If symptoms are severe, such as difficulty breathing or swelling of the throat, seek medical care right away rather than waiting for test results.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, where you can view and download the full report.

Who should consider this test?

Anyone who has had a reaction after eating sesame or sesame-containing foods, or anyone with a family history of food allergies who wants to check their sensitization status, should consider this test. It's also helpful for parents trying to figure out if a child's symptoms are linked to sesame exposure.

How can I naturally support my immune response to food allergens?

While there's no natural cure for a true allergy, some people find that supporting overall gut health with a balanced diet, probiotics, and reducing processed foods may help calm immune overreactions. Avoiding the trigger food entirely remains the most reliable way to prevent a reaction. Always introduce new foods slowly and in small amounts to watch for any response.

What does a high (positive) result mean?

A positive result means your immune system has produced sesame-specific IgE antibodies, indicating you're sensitized to sesame. This doesn't automatically mean you'll have a severe reaction every time, but it does mean sesame is a likely trigger for your symptoms and worth avoiding. Keeping a food and symptom journal can help you connect the dots between exposure and reactions.

What causes a positive sesame IgE result?

A positive result happens when your immune system has been exposed to sesame proteins and mistakenly flagged them as a threat, building antibodies against them. This can develop at any age, even if you've eaten sesame before without issues. Genetics, early childhood exposure, and other existing allergies can all play a role in whether this sensitization develops.

How often should I retest?

If your symptoms change, get worse, or you want to check whether sensitization has decreased over time (which sometimes happens, especially in children), retesting every 1-2 years is a reasonable approach. If you've eliminated sesame from your diet and want to see if you might tolerate it again in small amounts, retesting can help track that too. Use the trends feature in your account to compare results across tests.
