What's this test for?

This test is ideal if you're experiencing itching, hives, swelling, stomach upset, or other reactions after eating blueberries. It checks whether your immune system has formed antibodies against blueberry proteins, which is a sign of sensitization. This can help you figure out if blueberries might be behind your symptoms.

What's included in this test?

This test measures one specific marker: IgE antibodies targeted to blueberry proteins. IgE antibodies are part of your immune system's response to substances it mistakenly treats as threats, so measuring blueberry-specific IgE helps show whether your body has developed an allergic-type reaction to this fruit.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative IgE result means. If your result is positive, a practical next step is to avoid blueberries for a few weeks and see if your symptoms improve, then retest later if needed to confirm changes. If you ever have severe symptoms like trouble breathing or swelling of the throat after eating blueberries, seek emergency medical care right away. You can download the full lab report from your account anytime, and use the trends feature to track this marker over time if you retest.

How can I naturally support a healthy immune response to food sensitivities?

Keeping a food and symptom diary can help you notice patterns between what you eat and how you feel. Eating a varied, whole-food diet and managing stress can support overall immune balance. Avoiding the suspected trigger food, in this case blueberries, is usually the most effective step if you have a positive result and symptoms.

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 posted, and you can log into your account anytime to view them.

Who should consider this test?

This test is a good fit for anyone who has noticed itching, hives, stomach discomfort, or other reactions after eating blueberries or blueberry-containing foods. It's also useful for people trying to narrow down a list of suspected food triggers. Parents wondering about a child's reaction to berries may also find this helpful, though testing itself is done on a blood sample from the individual being evaluated.

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 face, stomach cramps, nausea, or digestive upset after eating blueberries. Some people also notice nasal congestion or a scratchy throat. If these symptoms consistently follow blueberry consumption, this test can help confirm a possible connection.

What does a positive result mean?

A positive result means your immune system has made IgE antibodies against blueberry proteins, showing you're sensitized to this allergen. This doesn't automatically mean you'll have a reaction every time you eat blueberries, but it does raise the chance that blueberries are contributing to your symptoms. Combining this result with how your body actually reacts to blueberries gives the clearest picture.

What does a negative result mean?

A negative result means no significant blueberry-specific IgE was detected, so blueberries are less likely to be the cause of your symptoms. If you're still having reactions after eating berries or mixed fruit, it may be worth looking at other ingredients or foods eaten around the same time. Keeping a symptom log can help identify other possible triggers.

How often should I retest?

If you're avoiding blueberries and your symptoms improve, there's usually no need to retest right away. If you reintroduce blueberries later or want to check whether sensitization has changed over time, retesting every year or two is a reasonable approach. Retesting sooner may make sense if new or worsening symptoms appear.
