What's this test for?

This test is ideal if you're experiencing bloating, stomach discomfort, skin flare-ups, or other unexplained symptoms after eating and you suspect bananas might be a trigger. It measures your immune system's IgG antibody response to banana proteins, which can help you figure out if this common food is contributing to your symptoms. It's a useful starting point if you've noticed a pattern between eating bananas and feeling unwell.

What's included in this test?

This test checks your IgG antibody response specifically to banana proteins. IgG antibodies are part of your immune system's memory, and elevated levels to a specific food can sometimes be linked to delayed sensitivity reactions, which is why this single-marker test focuses on giving you a clear, targeted answer about banana specifically.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what your IgG level means and how it compares to the normal range. If your level comes back elevated, a practical next step is trying an elimination approach — cutting bananas from your diet for a few weeks and tracking how you feel before slowly reintroducing them. You can download the full lab report from your account anytime, and if you retest down the road, the trends feature lets you see how your levels change over time.

How can I naturally support digestive comfort?

If bananas seem to be bothering you, simple swaps like trying other fruits (berries, apples, or citrus) can help you keep variety in your diet without the discomfort. Eating smaller portions, pairing food with fiber and protein, and keeping a food-and-symptom journal can also help you spot patterns. Staying hydrated and eating slowly can ease digestion in general, regardless of the specific trigger.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted, and you can log into your account anytime after that to view and download your report.

Who should consider this test?

Anyone who regularly eats bananas and notices symptoms like bloating, stomach cramps, skin irritation, or fatigue afterward may want to consider this test. It's also useful if you're trying to narrow down a longer list of suspected food triggers and want a targeted answer rather than a broad panel. People managing chronic digestive discomfort who haven't found a clear cause may also find it a helpful piece of the puzzle.

What symptoms indicate I may need this test?

Common signs include bloating, gas, stomach pain, diarrhea or constipation, skin rashes or hives, headaches, or fatigue that seem to show up after eating bananas or banana-containing foods. If you've noticed these symptoms happening repeatedly after the same meals, it may be worth checking whether banana is a contributing factor. Keeping a simple food diary before testing can help you connect the dots.

What does a high IgG result mean?

A high result means your immune system has produced more antibodies to banana proteins than typical, which some people associate with food sensitivity symptoms like bloating or skin issues. It doesn't necessarily mean a dangerous allergy — it's different from a true allergic reaction — but it can be a useful clue if you're trying to connect diet to how you feel. Many people use this information to guide a temporary elimination diet and see if symptoms improve.

What causes a high IgG response to a specific food?

Frequent consumption of a food, gut lining sensitivity, or an overactive immune response can all contribute to elevated IgG levels against a specific protein like banana. Some people develop these responses over time simply from eating a food often, especially if digestion is already stressed. Reducing how often you eat the food and giving your gut a break can sometimes help lower the response over time.

How often should I retest?

If you make dietary changes based on your first result, retesting after 2-3 months of avoiding banana can help you see if your antibody levels have changed. Otherwise, retesting once or twice a year is reasonable if you're generally monitoring food sensitivities. There's no need to retest sooner unless your symptoms change significantly.
