Food Sensitivity: Cyrex ARRAY #10 Multiple Food Immune Reactivity Screen

Cyrex Laboratories Array #10 measures antibody production (IgG/IgA) against 180 different foods (raw and/or modified), foods enzymes, lectins and artificial food additives (including meat glue, colorings, and gums).

Yes, even on a paleo gluten-free dairy/casein-free diet, you will often find trigger foods! A few common examples are nightshades, eggs, nuts, seeds, as well as some grains, veggies, and meats.


  • Fruits
  • Vegetables
  • Grains
  • Beans & Legumes
  • Nuts & Seeds
  • Fish & Seafood
  • Meat
  • Dairy & Eggs
  • Spices
  • Herbs
  • Gums
  • Brewed Beverages & Additives

Advantages of this test:

The Cyrex #10 is the new standard in food immune reactivity testing: while most labs use purified RAW proteins for their test panels, this does not factor in how we commonly consume certain foods. In order to test “real world exposures to real food,” Cyrex tests for both RAW and COOKED forms of foods on this panel.

Heating food above 118°F changes a food’s protein structure and therefore its antigenicity. As a result, an individual could react to the cooked form of a food but not the raw form, and vice versa.

For example, maybe a previous food sensitivity panel said that broccoli was non-reactive for you, but you notice that you experience negative symptoms whenever you eat it. If you were tested for broccoli using a standard RAW broccoli extract, then you may test non-reactive, but that doesn’t necessarily mean that COOKED broccoli is non-reactive as well. The problem is, you always eat your broccoli cooked.

Since we eat our meat cooked, that’s how Cyrex tests those proteins – as cooked beef/chicken/pork. Many vegetables are frequently eaten either cooked or raw, so Cyrex tests both forms in a number of cases (i.e. broccoli).

PLEASE NOTE: The Cyrex 10 does NOT test for GLUTEN sensitivity. There is a separate test for this, the Cyrex #3. If you are interested in this, let me know.

You MUST be eating the foods that are to be tested.

Antibody production is dependent upon exposure to a food.

For example, if you have been completely avoiding dairy, there should not be antibodies against dairy in your blood. Therefore, the test will not pick up any sensitivity to dairy.

Or, if you are eating the Standard American Diet (which typically does not include foods that are “staples” in the typical gluten-free diet like rice, sorghum, quinoa, and tapioca), you will not have antibodies against these gluten-free grains. It will be necessary to include these foods in the diet to stimulate antibody production and get accurate test results.

It typically takes 4-6 weeks of daily or regular exposure to a small amount of the food (a bite or two is usually sufficient). Add the foods into the diet for 4-6 weeks, then wait another 2-4 weeks for antibodies to develop, then test.

If individuals know that they are sensitive to a particular food and have already eliminated it, it is not recommended to add that food back into the diet. Instead, use the test (without food reintroduction) to indicate whether they have successfully reduced the elevated antibodies to this food.


Test Type: Blood (1 vial)

Shipping: The blood draw location will ship your blood directly to Cyrex Labs by UPS using the bag with your kit (leave the kit with them and they will take care of the rest). Blood may NOT be shipped on Friday (if the blood is collected on a Friday, it must be kept refrigerated over the weekend and shipped on Monday). These tests are available to practitioners in Europe via a 3rd party. Contact for additional information.

Cost: Array #10: $580 + shipping, approx. $7 within the U.S. (International shipping varies.)

Additional cost for blood draw? If you use one of the draw sites with which Cyrex contracts, there is no additional fee for the blood draw (note: contracted sites will NOT draw blood for individuals under 15 years of age). However, you may have your blood drawn at a location of your choice such as a local hospital lab. Just be aware that there will be likely be a small fee for this service. Note:

Additional Info:

Only 1 test kit is needed for multiple Arrays. Cyrex freezes the submitted blood sample for 90 days. In that time frame, if you’d like you run another Array test, the lab can use that same sample.

The turnaround time for testing is 14 days from the time the sample arrives at the lab.

Cyrex Labs always analyzes each sample TWICE. If there is more than a 3% discrepancy, the sample is analyzed for a 3rd time. If there is still more than a 3% discrepancy, the sample is thrown out, and they ask for a new sample. So, you can have confidence in the accuracy of the test results that you get back.

NY and Canada/International Clients:

  • The test cannot be done in New York state. The client’s address can be in New York, but the blood must be drawn in CT, NJ, PA, etc.
  • The client will be responsible for finding a blood draw location and return shipping. 2-day shipping is always recommended for International shipments, but the lab only rejects samples that were drawn longer than 10 days prior to it receiving them. Be sure to include the CDC permit and label.
