What's this test for?

This test is ideal if you're experiencing bloating, stomach cramps, skin flare-ups, or fatigue after eating and you suspect blackberries might be a trigger. IgG antibody testing looks at how your immune system reacts to this specific food, giving you a clue about whether it's contributing to your symptoms. It's a helpful starting point if you've been trying to figure out which foods to cut from your diet.

What's included in this test?

This test measures your immune system's IgG antibody response specifically to blackberries. Checking this single food marker helps you understand whether your body is reacting to this particular fruit, which is useful if you're narrowing down a list of suspected food triggers one at a time.

What happens after I get my results?

Your results will show up in your online account with a clear explanation of what a normal versus elevated IgG level means for blackberries. If your level comes back high, a simple next step is to remove blackberries from your diet for a few weeks and see if your symptoms improve, then consider retesting later to track changes. You can download a standard lab report from your account at any time, and the trends feature lets you compare this result to future tests if you retest for food sensitivities again.

How can I naturally support digestive comfort around food sensitivities?

Keeping a food and symptom diary can help you spot patterns even before or after testing. Eating smaller, more frequent meals and staying hydrated often eases digestive discomfort. Gut-supporting foods like plain yogurt, ginger, and fiber-rich vegetables may help calm occasional digestive upset, and reducing processed foods can lower overall inflammation.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your secure online account, and you'll be notified when they're ready to view.

Who should consider this test?

This test is a good fit for anyone who notices digestive discomfort, skin issues, headaches, or fatigue after eating blackberries or foods that commonly contain them. It's also useful if you're doing a broader elimination-diet investigation and want data on individual foods rather than guessing. People who eat blackberries regularly and want to rule out a sensitivity may also find this test helpful.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach pain, diarrhea or constipation, skin rashes or hives, headaches, and unusual fatigue that shows up a few hours to a couple days after eating. Because these symptoms can be delayed, it's often hard to connect them to a specific food without testing. If you notice a pattern after eating blackberries or foods containing them, this test can help confirm or rule out a sensitivity.

What does a high result mean?

A high IgG level to blackberries suggests your immune system is producing more antibodies against this food than typical, which some people associate with sensitivity symptoms. This doesn't mean a true allergy, but it may be worth trying an elimination period to see if symptoms ease. Pay attention to how you feel over a few weeks without blackberries in your diet.

How often should I retest?

If you eliminate blackberries and feel better, retesting in a few months isn't usually necessary unless you reintroduce them and want confirmation. If you're doing a broader elimination diet with multiple foods, retesting after 8-12 weeks can help you see if your levels have changed. Otherwise, retest anytime you want to check whether a food you've avoided is safe to bring back.

What should I do if my results are abnormal?

If your IgG level for blackberries comes back elevated, try removing blackberries and related foods from your diet for 2-4 weeks and track whether your symptoms improve. Reintroduce the food slowly afterward to see if symptoms return, which helps confirm the connection. If you experience severe reactions like difficulty breathing or swelling, seek medical care right away, as this could indicate a true allergy rather than a sensitivity.
