What is a 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.

Why measure food sensitivity?

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.

Q: Can I use my insurance to pay for the test?

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.

Q: How reliable are my results?

A: The reliability of the food sensitivity test is straight forward to confirm. Once you find out what you are sensitive to, eliminate or rotate those items from your diet to confirm the results. Instead of avoiding all possible food items one by one, our test makes it easier to focus on few key ingredients based on the test results.

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.
