What's this test for?

This test is ideal if you're experiencing itching, hives, swelling, or stomach upset after eating oranges or other citrus fruit. It checks whether your immune system has created antibodies against orange proteins, which is a sign of sensitization. This can help you understand if oranges might be behind your symptoms.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus elevated value means for this allergen. If your result is positive, a practical next step is to avoid oranges and citrus-based products for a while and see if your symptoms improve, then retest later if needed. You can download a standard lab report from your account at any time, and the trends feature lets you track this marker if you test again in the future. If you have a severe reaction like difficulty breathing or swelling of the throat, seek emergency medical care right away.

What is IgE allergy testing and why does it matter?

IgE is an antibody your immune system makes when it mistakenly treats a harmless food, like oranges, as a threat. Measuring orange-specific IgE tells you if your body has this reaction pattern, which is often linked to allergy symptoms. Knowing this helps you make informed choices about your diet and understand possible triggers for symptoms like hives, itching, or digestive discomfort.

How can I naturally support my body if I have a food sensitization?

If you test positive, the simplest approach is to reduce or avoid oranges and cross-reactive citrus fruits for a period of time and notice how your body responds. Keeping a food and symptom journal can help you spot patterns between what you eat and how you feel. Supporting your gut with a varied, whole-food diet and staying hydrated may also help your body manage occasional exposures. Always reintroduce foods slowly and stop right away if symptoms return.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. You'll be notified when your results are available in your online account, where you can view and download them.

Who should consider this test?

This test is a good fit for anyone who notices symptoms like itching, swelling, hives, or digestive upset after eating oranges or citrus products. It's also useful for people who suspect a citrus allergy but haven't confirmed it, or who want to check for sensitization before making dietary changes. Parents monitoring a child's reactions to citrus fruits may also find this test helpful.

What symptoms indicate I may need this test?

Common signs include itching or tingling in the mouth after eating oranges, hives or skin rashes, swelling of the lips or face, stomach cramps, nausea, or in more serious cases, trouble breathing. If these symptoms consistently show up after eating citrus fruit, this test can help confirm whether an IgE-mediated sensitization is involved.

What does a high result mean?

A high orange-specific IgE result means your immune system has produced antibodies that recognize orange proteins as a threat, which suggests sensitization. This doesn't automatically mean you'll have a reaction every time, but it does raise the likelihood that citrus exposure is connected to your symptoms. Avoiding oranges and watching how your body responds is a reasonable next step.

What causes a high IgE result to this allergen?

A high result usually happens because your immune system was previously exposed to orange proteins and mistakenly flagged them as harmful, creating specific antibodies. This can happen after repeated exposure through diet, and sometimes people with other allergies or a family history of allergies are more likely to develop it. Cross-reactivity with other fruits or pollens can occasionally contribute as well.

How often should I retest?

If you've eliminated oranges from your diet and are managing symptoms well, retesting once a year or if new symptoms appear is generally reasonable. If you're actively trying to reintroduce citrus fruits, retesting a few months later can help you track whether your sensitization has changed. Use the trends feature in your account to easily compare results over time.
