Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test

Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test

There is increasing awareness that foods may play a much larger role in immune reactivity than previously thought. We all eat food, and foods are a constant and sustained source of antigens, much more so than other things we may be exposed to. This test tests for IgA and IgG antibodies.

At Smart Nutrition we pride ourselves in offering the best cost possible for the Cyrex Array 10 Multiple Food Reactivity Screen 180 foods

 

The test looks at levels of IgA and IgG antibodies that are created when you react to a food.

This unique, revolutionary panel measures reactivity to 180 food antigens in the cooked, raw, modified and processed forms on the same panel.

Cyrex has developed a new way of testing for food immune reactivity.  This method arises from a foundation of science and medicine. Please scroll to the end for more info about getting the test if this bit is too technical for you.

  • Array 10 assesses immune reactivity to raw and cooked food proteins. This reflects how foods are most commonly eaten and is necessary because when food is heated or cooked, its protein structure changes.  The foods being assessed should best duplicate what patients eat.  Cyrex is the only laboratory to test for both raw foods which are eaten raw and cooked foods that are eaten cooked.
  • Reactive, pan-antigen isolates. Specific food antigens are known to cross-react with human tissues. If someone makes antibodies to these specific food antigens and has barrier permeability, those antibodies to the specific food antigen can begin attacking human tissue. This can result in tissue damage, autoimmune reactivity and eventually autoimmune disease.  Some cross-reactive food antigens include: gliadin, casein, food aquaporin, shrimp tropomyosin, and fish parvalbumin.  Pan-antigens are proteins that are common among multiple sources.  Examples include: shrimp tropomyosin, fish parvalbumin and hevein found in latex, and some fruits, nuts and vegetables. Tropomyosin is found in a variety of fish and crustaceans, which has been shown to cross-react with human tropomyosin.  Fish parvalbumin is found in a variety of fish species and is known to cross-react with human parvalbumin.
  • Tissue-bound artificial food colours. Artificial food colourings are used extensively in foods, and humans are regularly exposed to them by ingestion.  These chemical colourants form adducts (bonds or “bridges”) with proteins in humans; therefore, measuring the antibodies to these colourants will indicate whether or not they are responsible for a patient’s immune or autoimmune reaction.  A patient may not react to a particular food; however, they may react to the food once its protein is bound with an artificial colourant.  It is important to note that we are talking about food proteins binding to artificial food colorants, and vice versa.  The binding of artificial colourants to a food protein may increase the food’s antigenicity and ability to cause an enhanced immune reaction in patients.
  • Large gum molecules. Gums (xantham gum, gum arabic, guar gum) are in many foods, especially gluten-free and dairy-free processed products.  They can also be found in soups, juices, jams, salad dressings, soy products, dairy products such as milk and yogurt and others.  Gums are large molecules (200,000-5,000,000 Daltons) and parts of their molecules have the same molecule sequences as other food proteins; this is known as molecular mimicry.  These can cross-react with other food proteins, causing an immune reaction in patients.
  • Binding isolates (lectins and agglutinins). Lectins are glycoproteins that bind carbohydrates, and agglutinins bind cells together. Lectins and agglutinins are found in about 30% of foods. Lectin is only one among hundreds of proteins found in beans, so it is normally not possible to accurately measure the lectin antibody when it is mixed with many other proteins.  However, by using purified lectins, the most antigenic protein in beans, peanuts, etc, the testing becomes the most accurate and specific method to detect antibodies to these inflammatory food antigens.  Array 10 includes lentil and pea lectins, as well as, beans, soybean and peanut agglutinins.
  • Amplified antigenic proteins and peptides. Array 10 includes specific proteins and peptides that are within the entire food proteins. Examples include shrimp tropomyosin and shrimp protein, cashew vicilin and cashew proteins, pineapple bromelain and pineapple proteins, and rice endochitinase and rice proteins.  These antigens are highly purified recombinant proteins (proteins made via biomolecular engineering) and synthetic peptides (short chains of amino acids). By targeting specific antigens within the entire food proteins, Array 10 increases the sensitivity and specificity for food immune reactions.
  • Oleosins. Cyrex tests for oleosins, which are the oil proteins found in seeds and nuts.  Some patients may not have a reaction to the proteins in seeds or nuts such as sesame, peanuts, and others; however, they may react to the protein oil in a seed or nut.  This is why a patient may react to both peanut and peanut oleosins, or may have a reaction only to peanut oleosins. In the latter case testing only for peanut and not peanut oleosins would give a false negativ
  • Meat glue. Meat glue, also known as transglutaminase or thrombian, is a powder used in the food manufacturing industry to adhere smaller pieces of meat to make one large fillet, or to turn flakes of white fish into imitation crab meat, or form chicken scraps into nuggets. It is also used to thicken some milks, yogurts and egg whites. According to the packaging label on meat glue there is also maltodextrin and sodium casein with transglutaminase.
  • Dual body detection system. Both IgG and IgA isotope are involved in the immune response, Array 10 measures IgG and IgA antibodies for each food. Clinically IgA is an indication of the muscle immune response and IgG is an indication of the circulatory immune response. Measuring both ensures and enhances the detection of food immune reactivity.

The Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test is a blood test that requires a blood sample which will then need to be centrifuged. Centrifuge can be carried out at the lab if the sample is received within 24 hours from the blood draw.

You will need to arrange for a blood sample to be collected either at a laboratory in London, by a nurse at your GP service or at a private clinic or hospital. Any fee for this service is not included with the test fee.

 

While Cyrex is unable to provide an exhaustive list of medications due to the interactive complexities and varieties of medications and patient circumstances, the following have been noted:

  • Immunosuppressant and corticosteroid drugs can reduce antibody production and cause false negative results.
  • Limited assessments on the effects of aspirin, acetaminophen, and antipsychotics on Arrays 1-4 have been performed. No noticeable effects were observed.
  • Inhalers can affect the results of Cyrex’s oral fluid testing (Array 1). Wait two weeks after completion of inhalant dosages before collecting the specimen.
  • Unknown cross-reactive epitopes from foods and microorganisms may stimulate the antibody production in the absence of a true antigen. Cyrex has already developed Array 4 in order to recognise the most common antigens in this regard.
  • A gluten-free diet can cause false negative results on gluten protein/peptide tests.
  • Certain conditions, such as ileal pouch surgery, may cause a false positive celiac serology.

Please do not stop any medication without your doctor’s consent.

The Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test is suitable for ages  – 3 years and above.

Once you’ve collected your Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test samples, please send them back to the lab using the prepaid return label.

The results for the Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test will take 16-23 days.

Your Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test results will be emailed to you.

What if I have been avoiding certain foods, can I test these with the Cyrex Array 10 Multiple Food Reactivity Screen 180 foods test?

If you have been avoiding foods for a while the immune response can be reduced and it is possible to get a false negative results so you do need to have eaten the foods you are testing.

Re introducing Foods

Introduce the food every day for 7 days in ‘normal’ quantities – eat a sandwich, or piece of toast, some cheese, a yoghurt, or a glass of milk etc.
You can arrange your blood draw for  25 – 30 days after day 7.
I usually tell people if day 1 of eating gluten is Day 1. You want to run the test around Day 35. It doesn’t have to be precisely day 35, but if you aim for that then you’ll be good.
If you have been avoiding a broad range of foods we might recommend you do a full food reintroduction process of adding in 1 food at a time, waiting 3 days or so before adding in the next food to assess symptoms. If they get significant symptoms from the food, then it might be better to consider that a positive and leave it out and move on to the next food.
Once all the foods have been added in, which can take several weeks or even a couple of months depending on how many and how reactive you are, you can then do the blood test a month after the last food was added.
Please do not introduce any foods you know you are allergic too  – this is commonly shellfish and peanuts etc but can be any food and can result in a very strong reaction. If you are interested in testing your self for possible food allergies please visit this page.
Please do get in touch with our admin team [email protected] if you need further clarification about any of the above.
