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:

  1. Immunosuppressant and corticosteroid drugs can reduce antibody production and cause false negative results.
  2. Limited assessments on the effects of aspirin, acetaminophen, and antipsychotics on Arrays 2-4 have been performed. No noticeable effects were observed.
  3. Unknown cross-reactive epitopes from foods and microorganisms may stimulate the antibody production in the absence of a true antigen.
  4. If a patient is completely gluten-free for more than 4 weeks, there is a potential for a false negative result on Array 3. Array 4 was designed for a patient already on a GF diet.

Patients should consult with their HCP regarding any questions or concerns they may have.

Test cancellations should be submitted by fax to (602) 759-8331. Test cancellation fax forms are available under the "Forms" section of this site. Test cancellations are only accepted prior to specimen accessioning. A request for test cancellation received after accessioning cannot be honored, and the test will be performed at the normal price. Phlebotomy services and shipping costs incurred by the lab will be deducted from the refund amount, unless the refund is due to the inability to provide results on a specimen due to laboratory error. Refunds will be provided based on the method of payment and are only made to the account or person who paid for the test. Please allow up to two weeks to process refunds.

Cyrex encourages patients to contact their insurance provider before having testing performed. The insurance provider will need the testing CPT® codes, which are listed on this website, in the Antigen tab of the Arrays section. *Note: if you also provide a diagnosis code from your healthcare professional, the insurance company can give you a more accurate reimbursement estimate.
