Intestinal Antigenic Permeability Screen (Array 2)-Cyrex Kit:
Note: This is a test kit that will be mailed to you. It requires a blood draw. It is your responsibility to arrange the blood draw for your kit and payment of your specimen collection.
Fasting Required: No
Lab: Cyrex Laboratories
Specimen: Blood, serum
Results: Average processing time 14 business days
Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Special Instructions: Are there any medications, foods, conditions, or other factors that could interfere with the results of a Cyrex test? Yes. While Cyrex is unable to provide an exhaustive answer to this question due to the interactive complexities and varieties of medications and patient circumstances, the following has 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.
- 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 recognize the most common antigens in this regard.
- Wait at least 60 days after the completion of steroids to do testing. It takes this period of time for the medication to clear the system and allow the normalized production of antibodies, required for immune testing, to resume.
- Eating a high fat meal prior to your blood draw can cause your serum specimen to be lipemic. Lipemic specimens are rejected by Cyrex Labs.
- Patients should consult with their HCP regarding any questions or concerns they may have.
Notice: Shipments should be sent Monday through Thursday.
Description: Array 2 measures intestinal permeability to large molecules, which inflame the immune system. Identifies the route of damage to the intestinal barrier and the presence of immune reactivity to Lipopolysaccharides (LPS), a key indicator of systemic inflammation leading to autoimmune conditions.
Recommended For Patients Who:
- Present multiple symptom complaints (including Chronic Fatigue Syndrome)
- Suffer from abnormal immune cell count and function (including autoimmune diseases)
- Complain of food sensitivity and intolerance
Antigens Tested:
- Actomyosin - IgA
- Occludin/Zonulin - IgG
- Occludin/Zonulin - IgA
- Occludin/Zonulin - IgM
- Lipopolysaccharides (LPS) - IgG
- Lipopolysaccharides (LPS) - IgA
- Lipopolysaccharides (LPS) - IgM
