Questions about IgG Food Sensitivity Test
A: Our Food Sensitivity Test checks for Immunoglobulin G (IgG) antibodies produced from sensitivity to certain foods. We do not test for IgA or IgE antibodies (some of those require a lot more blood, which might need to be drawn by a nurse or phlebotomist).
A: No. This is a lab-developed test (LDT). Our labs regularly develop new tests that are monitored by the state health regulatory bodies as well as CMS (Centers for Medicare and Medicaid Services) and may not always require FDA approval. The CLIA certification allows labs to develop such tests.
Our test will be carried out by USBioTek, based in Seattle, WA. For over 15 years, the lab has been testing thousands of patients, and hundreds of doctors regularly use it for their patients.
A: Unfortunately, no. A consultation adds extra cost, however, we are working on adding telehealth support in case you want to make a separate appointment to talk to a physician.
A: Each test is run twice to ensure it passes our strict testing protocols. The lab also runs reference samples for calibration to ensure the results are within the expected ranges. Additionally, the lab needs to pass very strict regulatory requirements for state and CLIA certification in order to test human samples.
A: The test marks your sensitivities to specific foods on a scale of 0 to IV (from low to high). Based on your results, the lab designs a diet rotation plan that recommends what to eat for next few days. This allows confirmation of any sensitivities flagged in the report, or to ignore others that might be due to cross-contamination from other unknown reasons.

Several factors might affect your results:
There are cases where low IgG reactivity is observed, for example:
High IgG sensitivity may be observed in very sick patients or when the body is producing high levels of immunoglobulins that cross-contaminate the signals.
Because Immunoglobulin G (IgG) antibodies may be elevated due to other reasons, it may not always be easy to pinpoint the exact cause of sensitivity. That’s why following a diet rotation plan, included in the test results, is essential to confirm the results. Without the test, one needs to keep track of all the food items in their diet and work on eliminating them one-by-one. The test allows to narrow down the suspect foods and the diet rotation plan helps confirm the most common offenders among them.
Diagnostic tests are used as a way to eliminate or confirm certain conditions or symptoms. It is important to understand that every test has limitations, and you may not always get the desired results with this test alone.
After reviewing all the above information and when you are ready to order, pick the test you want to order. Check the steps involved in placing the order and carefully follow the instructions after your kit arrives. Once the results are available, we suggest to review them with your doctor. Additionally, it is very important to follow the diet rotation plan to confirm the sensitivities to the suspect foods highlighted in the report. This step is critical in order to eliminate them from your diet.

Our tests do not substitute the advice of a trained physician or health professional. Please do not use the results for diagnosing or treating any health problems. We encourage you to share the results with your primary care physician before making any decision based on the test results.
