What's this test for?

This test is ideal if you're experiencing itching, swelling, hives, stomach upset, or other reactions after eating horseradish or foods that contain it. It checks whether your immune system is producing an allergic response to horseradish specifically, helping you figure out if it's the cause of your symptoms. This is useful if you suspect a food allergy but haven't been able to pinpoint the trigger.

What's included in this test?

This test measures horseradish-specific IgE, the antibody your immune system makes when it treats horseradish proteins as a threat. Checking this single, targeted marker gives you a clear yes-or-no signal about whether horseradish is triggering your allergic symptoms, without needing a broader panel.

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. If your result is elevated, a practical next step is to avoid horseradish and closely related foods and watch for symptom changes, then retest later if needed to confirm improvement. You can download a standard lab report from your account at any time, and if you test again in the future, the trends feature lets you track how your levels change over time. If you ever experience severe symptoms like trouble breathing or swelling of the face and throat, seek emergency medical care right away.

How can I naturally support a sensitive immune system?

Some people find that reducing overall inflammation through a balanced diet, staying hydrated, and getting enough sleep helps their body respond better to allergens. Probiotic-rich foods like yogurt and fermented vegetables may also support gut and immune health, which plays a role in allergic reactions. Avoiding known triggers is still the most effective way to reduce symptoms while you work on general immune support.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll be notified as soon as your results are available in your account, so you can log in and review them at your convenience.

Who should consider this test?

Anyone who notices symptoms like hives, itching, swelling, or digestive discomfort after eating horseradish or foods seasoned with it should consider this test. It's also helpful for people who've had unexplained allergic reactions and want to narrow down the specific cause. If you have a family history of food allergies, testing can help you be proactive.

What symptoms indicate I may need this test?

Common signs include itching or tingling in the mouth, hives or skin rashes, swelling of the lips or tongue, stomach cramps, nausea, or a stuffy or runny nose after eating horseradish. In more serious cases, symptoms can include difficulty breathing or throat tightness. If you notice these symptoms recur after eating horseradish-containing foods, this test can help confirm the connection.

What does a high result mean?

A high horseradish-specific IgE result means your immune system has developed an allergic sensitivity to horseradish proteins. This doesn't always predict how severe a reaction will be, but it does suggest you should limit or avoid horseradish going forward. Keeping a food and symptom diary can help you understand how your body reacts in real life.

What causes a high result?

A high result happens when your immune system mistakenly identifies proteins in horseradish as harmful and creates antibodies against them. This can develop at any point in life, even if you've eaten horseradish without issues before. Genetics, an already sensitive immune system, or cross-reactivity with related plants like mustard or wasabi can all play a role.

How often should I retest?

If you've eliminated horseradish from your diet, retesting after 6 to 12 months can help you see if your sensitivity has changed. If your symptoms change or worsen, retesting sooner can help you stay informed. Otherwise, testing once to confirm the allergy is often enough for most people.
