What's this test for?

This test is ideal if you're experiencing bloating, digestive discomfort, skin issues, or unexplained fatigue that seems tied to what you eat. It checks whether your immune system reacts to black olives specifically, which can help you figure out if this food is contributing to your symptoms. Many people use this test as part of a broader effort to identify hidden food triggers.

How should I prepare for this test?

How can I naturally support digestion if I'm sensitive to a food like black olives? Focus on eating a varied diet with easily digestible foods like cooked vegetables, lean proteins, and bone broth while your gut recovers. Adding probiotic-rich foods such as yogurt or kefir and staying well hydrated can also help calm inflammation. If you suspect a sensitivity, keeping a simple food and symptom journal alongside your test results makes it easier to spot patterns.

What's included in this test?

This test measures your immune system's IgG antibody response specifically to black olives. IgG reactions are different from classic allergies — they tend to reflect delayed sensitivities that can contribute to digestive or inflammatory symptoms hours or days after eating a food, so knowing your level helps you connect the dots between diet and how you feel.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a normal versus elevated reaction range looks like for black olive IgG antibodies. If your level comes back elevated, a practical next step is to remove black olives from your diet for a few weeks and see if your symptoms improve, then reintroduce slowly to confirm. You can download a standard lab report from your account at any time, and if you retest later you'll be able to track changes over time using the trends feature.

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 as soon as your report is 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 if you regularly eat black olives or olive-based products (like tapenade, Mediterranean dishes, or olive oil blends with pulp) and notice symptoms such as bloating, headaches, joint discomfort, or skin flare-ups afterward. It's also useful for people doing an elimination diet who want lab data to confirm what to remove. If you have no regular exposure to black olives, this specific test may not be very informative for you.

What symptoms indicate I may need this test?

Common signs that a food sensitivity might be at play include bloating, gas, stomach cramps, diarrhea or constipation, skin rashes or eczema flare-ups, headaches, joint pain, and unexplained fatigue that shows up hours after eating. These symptoms are often delayed, which makes it hard to connect them to a specific food without testing. If you've already tried cutting out common allergens without relief, testing individual foods like black olives can help narrow things down.

What does high black olive IgG mean?

A high result means your immune system is producing more antibodies against black olive proteins than typical, which suggests your body may be treating this food as a low-grade irritant. This doesn't mean you're allergic in the classic sense, but it can be linked to symptoms like bloating or fatigue after eating olives or olive-containing dishes. Many people find that reducing or eliminating the food for a few weeks and monitoring symptoms is a practical first step.

What causes a high IgG reaction to a specific food?

IgG reactions can develop when a food is eaten very frequently, when gut lining is more permeable than usual (sometimes called a 'leaky gut'), or simply due to individual immune variation. Repeated exposure to the same food over time is one of the most common contributing factors. Stress, poor sleep, and an imbalanced gut microbiome can also make the gut more reactive to certain foods.

How often should I retest?

If you make dietary changes based on an elevated result, retesting after 3 to 6 months is a reasonable timeframe to see if your antibody level has come down. Retesting sooner usually won't show much change, since antibody levels shift gradually. Tracking your results over time in your account makes it easy to see your progress.
