What's this test for?

This test is ideal if you're experiencing itching, hives, swelling, or stomach upset after eating plums or other stone fruits. It checks whether your immune system has developed a specific antibody response to plum proteins. It's also useful if you suspect a cross-reaction with pollen allergies, since plum allergy is sometimes linked to birch pollen sensitivity.

What's included in this test?

This test measures one specific marker: IgE antibodies that react to plum proteins. IgE antibodies are the immune system's way of flagging a substance as a threat, so finding plum-specific IgE tells you whether your body has been sensitized to this fruit.

What happens after I get my results?

Your results will show up in your account along with an explanation of what's considered a normal versus elevated range for this antibody. If your result is positive, a practical next step is to avoid plums and watch for reactions with related foods like peaches, cherries, or apples, since cross-reactivity is common. If your levels are very high or you've had a severe reaction like trouble breathing, seek medical care right away. You can download the full lab report from your account anytime and use the trends feature to track your results if you retest in the future.

How can I naturally support a healthy immune response to food allergens?
Eating a varied diet rich in fruits, vegetables, and fermented foods can help support a balanced gut and immune system. Reducing processed foods and added sugar may also help lower overall inflammation. Staying hydrated and managing stress can support your body's natural resilience, though these steps don't replace avoiding a food you're sensitized to.
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 they're available in your account, so there's no need to call or wait on hold to find out.
Who should consider this test?
This test is a good fit for anyone who notices symptoms like hives, itching, swelling, or digestive discomfort after eating plums. It's also worth considering if you have other known fruit or pollen allergies, since these often overlap. Parents tracking a child's reactions to new foods may find this test helpful too.
What symptoms indicate I may need this test?
Common signs include itching or tingling in the mouth, hives, swelling of the lips or throat, stomach cramps, nausea, or in rare cases, difficulty breathing after eating plums. Symptoms that show up consistently after eating this fruit, even in small amounts, are a strong signal to get tested. If you've noticed a pattern with other stone fruits too, that's also worth flagging.
What is IgE and why does it matter?
IgE is a type of antibody your immune system makes when it mistakenly identifies something harmless, like a plum protein, as dangerous. Higher levels of plum-specific IgE suggest your body is primed to react if you eat this fruit again. It matters because knowing your sensitization status helps you make informed choices about what to eat and how to manage symptoms.
What does a high result mean?
A high result means your immune system has produced a notable amount of antibodies against plum proteins, suggesting you're sensitized and may react if you eat plums. The higher the number, the more likely a reaction could occur, though severity varies from person to person. A practical step is to avoid plums and related fruits, and keep track of any reactions in case you need to seek care.
How often should I retest?
Food sensitivities can change over time, so retesting every 1-2 years is reasonable if you're monitoring a known allergy or trying to see if you've outgrown it. If you've had a recent reaction or started an elimination diet, retesting after 6-12 months can help confirm changes. Always factor in how your symptoms have evolved when deciding on timing.
