Before Taking A CYREX Test
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 has been noted:
a. Immunosuppressant and corticosteroid drugs can reduce antibody production and cause false negative results.
b. Limited assessments on the effects of aspirin, acetaminophen, and antipsychotics on Arrays 1-4 have been performed. No noticeable effects were observed.
c. 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.
d. 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.
e. A gluten-free diet can cause false negative results on gluten protein/peptide tests.
f. Certain conditions, such as ileal pouch surgery, may cause a false positive celiac serology.1
