With 96 foods, this at-home IgG test for food sensitivity is ideal for checking IgG antibody response to some of the most common ingredients in our daily diets.
Using a few drops of blood with a finger prick sample, it can help identify well known allergens including dairy, eggs, meat, shellfish, nuts, wheat, herbs, spices, and candida yeast. Many of these foods can cause discomfort and other mild symptoms including stomach pain, bloating, rashes, and indigestion. It allows elimination of foods you are not comfortable eating.
Our ELISA IgG test runs every sample twice for best results. A unique diet rotation plan based on your results will recommend foods you can eat in next few days to confirm your sensitivities.
For 240 foods, try our one-of-a-kind Comprehensive Food Sensitivity Test.

Unlike a food allergy test, a food sensitivity blood test measures the subtle response to common ingredients in the diet with IgG antibodies. These are the foods that may not be making you sick but cause discomfort after eating.
Once you find out that your body is producing immunoglobulin G (IgG) protein antibodies in response to certain foods, you can reduce or eliminate the consumption of those items. The sensitivity is measured on scale of 0 to 4 (zero means no sensitivity and 4 means high sensitivity). You can download a sample report by clicking on 'Get Sample Report' on top of this page.
Common symptoms of food sensitivity include bloating, unease, nausea, headache, mood swing, and fatigue. Common examples include lactose intolerance when people feel bloated after consuming milk, or brewers yeast allergy, or sensitivity to soy, corn or garlic.
Testing for food sensitivity can help improve quality of life by eliminating common offenders or rotating them on a regular basis. The simplicity of test is that once your results are received, you can eliminate suspect foods to confirm how they have been affecting you. A diet rotation plan unique to your results makes the process easier.
The test will measure following items:
Dairy: Casein, Cheddar Cheese, Cow's Milk, Goat's Milk, Whey.
Grain, Legumes and Nuts: Almond, Barley, Buckwheat, Chestnut, Chickpea, Coconut, Corn, Gliadin, Gluten, Green Bean, Green Pea, Hazelnut, Kidney Bean, Lentil, Lima Bean, Oat, Peanut, Pecan, Pinto Bean, Rye, Soybean, Spelt, Walnut, Wheat, White Rice.

A: You will receive the kit within 3-5 business days with a prepaid return envelope for shipping within US. After you ship the sample and it is received by our lab, you get the results in 5-7 business days.
A: The report with your results will be easy to understand and will have all the necessary details. It will list all the food items you are tested for and the corresponding sensitivity levels on a scale of 0 to 4. Zero means minimal or no sensitivity and 4 means high sensitivity. You can download a sample report by clicking on 'Get Sample Report' on top of this page.
A: Your test is performed at USBioTek Laboratories, a leader in IgG, IgA, IgE antibody testing. Some people may notice that their results don't match their expectations (e.g., certain known sensitivities from previous testing didn't show up this time, or nothing was flagged).
Here are few other things the lab does to ensure you get the most out of your test.
I. Steps the lab takes to provide the most accurate results:
Every sample runs twice for most accurate results: To consistently deliver the most accurate and repeatable results every sample runs in duplicate. Their advanced robotic testing is fully automated to avoid any human errors and they double check test results for inconsistencies so that you are confident they're accurate.
Every sample runs with well calibrated reference samples: They always confirm the quality of their antigens, and use controls and reference materials to make sure their assays are of the highest quality available. Each batch includes reference controls with known antibody levels for validation of the testing process.
Labs and equipment are regularly calibrated: Periodic inter- and intra-lab testing comparison is performed to verify precision and accuracy of the results. The lab regularly runs standard calibration samples internally and with other labs to ensure consistent quality across the tools.
External accountability: they allow third-party agencies to verify their quality, with accreditation from CLIA, COLA, and CAP ensures their lab protocols exceed the industry standards.
II. What might impact your results:
Certain medications: the Food Sensitivity IgG Test checks for specific antibodies in your blood sample, which might be affected by certain medicines. Anything that suppresses the antigen (responsible for triggering sensitivity) or the corresponding antibody levels might affect your results. Immunosuppressive medications, antihistamines, anti-inflammatories (steroids, NSAIDs), anti-cancer agents (alkylating agents, antimetabolic agents, antilymphocytic agents, cyclophosphamide, cyclosporine, etc.), anti-convulsive medications (phenytoins) might interfere with your results.
Cross-influence from other antibodies: certain antibodies might interfere with the results (e.g., honey interfering with pollen results or certain toxic chemicals might suppress antibody production)
When you last consumed a given food: If you have known sensitivities and you avoid consuming those foods, the antibody levels will slowly reduce over time (e.g., gluten-free diet reducing the antibodies against wheat, rye, barley)
Certain medical conditions: about 2.5% of the adult population may carry an inherited IgG subclass deficiency that may have low reactivity to our IgG test.
Advanced age, malnutrition/malabsorption, or chronic infections are known to cause acquired IgG deficiencies.
No IgG antibodies are produced: The test specifically measures IgG antibodies and if no rise in antibodies is caused despite a person is sick or shows symptoms the test will not show antibodies.
Radiation therapy is known to cause low IgG levels.
Protein-losing conditions such as enteropathy and nephropathy can result in apparent selective deficiency of IgG.
Intensive (“extreme”) exercise training can affect your results
Smoking associated with chronic bronchitis can result in low IgG
Unknown reasons: no test is perfect and in certain rare cases with unknown cause might affect the antibodies levels.
III. What should be next steps:
Review the symptoms carefully as discomfort or inflammation may be due to many reasons. The test can only report IgG antibodies.
Follow the diet rotation plan to confirm the results--without giving the test results a fair chance it's impossible to confirm the results.
Follow the food elimination procedure for all food items in Class I and above, and repeat in two months to confirm the results.
A: You can use HSA (or FSA/MSA/HRA) accounts to pay for the tests since these are prescription tests (for further confirmation, please check the IRS publication#969). However, please ensure you are not going outside your specified max and min deductible limits. We do not have the capability to process the insurance claim. Insurance plans vary by individuals, therefore we can not guarantee your HSA payment will always be processed by your plan. Please talk to your insurance provider if you have any further concerns.
A: For testing your samples, we have partnered with CLIA-certified labs that are used by physicians across the US. These labs are regulated by the states, as well as Centers for Medicare and Medicaid Services (CMS). Additionally, the College of American Pathologists (CAP) requires inter-laboratory tests to ensure the ranges established by each lab do not drift or are not out of acceptable ranges. This is done by regularly testing reference samples between different labs. Finally, the labs test thousands of sample for different age groups and health conditions, and have well established reference data to compare your results against this large pool.
A food sensitivity test can help understand your body's response to common foods in everyday diets.
The test can help you find the root cause of dietary problems that may not be easy to resolve otherwise.
Even if you find you are not sensitive to the suspected food items, it helps to get the food part out of discussion in order to find the actual problem.
The test provides a full range of your sensitivity levels on a scale of 0 to 4. Even if you are sensitive to certain foods, it allows you to rotate those items in order to get a balanced diet.
