What's this test for?

This test is ideal if you're experiencing unexplained digestive issues, bloating, headaches, fatigue, or skin problems that you suspect might be related to certain foods. It measures your body's IgG immune response to 11 common foods including wheat, dairy, eggs, soy, and peanuts to help identify potential food sensitivities. Many people use this test when they want to understand which foods might be causing discomfort or interfering with their overall well-being.

How should I prepare for this test?

You should be regularly consuming the foods being tested in the weeks leading up to your test, as IgG antibodies develop in response to food exposure. Avoiding these foods before testing may result in falsely low antibody levels that don't accurately reflect your typical reactions. No fasting is required, and you can take your regular medications unless instructed otherwise by your healthcare provider.

What's included in this test?

Cacao (Chocolate) (f93) IgG Casein (f78) IgG Codfish (f3) IgG Coffee (f221) IgG Egg White (f1) IgG Maize/Corn (f8) IgG Peanut (f13) IgG Soybean (f14) IgG Tomato (f25) IgG Wheat (f4) IgG Yeast (Bakers/Brewers) (f45) IgG

This panel measures your IgG antibody response to 11 commonly consumed foods: Wheat, Egg White, Codfish, Peanut, Soybean, Maize/Corn, Tomato, Casein (milk protein), Cacao (chocolate), Coffee, and Yeast. These foods were selected because they're frequently consumed and commonly associated with food sensitivities that can cause digestive discomfort, inflammation, fatigue, and other symptoms. By testing your IgG levels to each food, the panel helps identify which foods your immune system may be reacting to, providing insights for potential dietary adjustments.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining your IgG antibody levels for each food tested and what they may indicate about your body's response to these foods. These notes include personalized recommendations like which foods to consider eliminating temporarily, how to do an elimination diet properly, or whether you should work with a nutritionist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful if you retest after dietary changes.
Who should consider getting this test?
This test is ideal for adults experiencing chronic digestive issues like bloating, gas, or irregular bowel movements that haven't been explained by other tests. It's also useful for people with unexplained fatigue, frequent headaches, skin problems like eczema or rashes, or general inflammation that they suspect might be food-related. If you've tried eliminating common trigger foods without clear results or want a more systematic approach to identifying food sensitivities, this panel can provide helpful guidance.
What symptoms indicate I may need this test?
Common symptoms that suggest food sensitivities include persistent bloating, gas, diarrhea, or constipation that occurs without a clear pattern. You might also experience frequent headaches or migraines, ongoing fatigue that doesn't improve with rest, skin issues like eczema or hives, joint pain, or brain fog. If you notice these symptoms seem to get worse after eating but can't pinpoint which foods are the culprits, this test can help identify potential triggers.
How can I manage food sensitivities naturally?
Start by temporarily eliminating foods that show elevated IgG levels for 4-6 weeks to allow your immune system to calm down, then gradually reintroduce them one at a time while monitoring symptoms. Support your gut health with probiotic-rich foods like yogurt, kefir, and sauerkraut, and include anti-inflammatory foods like fatty fish, leafy greens, and berries. Keeping a detailed food diary can help you track which foods trigger symptoms, and working with a nutritionist can help ensure you maintain balanced nutrition while avoiding trigger foods.
What is IgG and how does it relate to food sensitivities?
IgG (Immunoglobulin G) is an antibody your immune system produces in response to substances it encounters, including foods. When you eat certain foods regularly, your body naturally produces IgG antibodies as a normal response. However, elevated IgG levels to specific foods may indicate that your immune system is reacting more strongly to those foods, which some practitioners believe could contribute to symptoms like digestive discomfort, inflammation, or fatigue, though this remains a topic of ongoing debate in the medical community.
What does a high IgG level to a specific food mean?
A high IgG level indicates that your immune system has produced more antibodies in response to that particular food, suggesting frequent exposure and a stronger immune response. While this doesn't necessarily mean you have a true food allergy, some healthcare providers interpret elevated IgG as a sign of food sensitivity that may be contributing to your symptoms. The clinical significance of elevated food-specific IgG is debated, so results should be interpreted alongside your symptoms and with guidance from a healthcare provider.
How often should I retest my food sensitivities?
If you've eliminated trigger foods and made dietary changes, consider retesting in 6-12 months to see if your IgG levels have decreased and whether you might be able to reintroduce some foods. If your initial results were normal but symptoms persist or new symptoms develop, you might retest in 6 months or test for different foods. Keep in mind that IgG levels can change over time based on your diet, gut health, and overall immune function, so periodic retesting can help track your progress.

What this means

Your IgG antibodies to wheat are elevated, which may indicate your immune system is reacting to wheat proteins. This could be contributing to symptoms like bloating, fatigue, digestive discomfort, or inflammation you've been experiencing after consuming wheat-based foods.
