Anyone heard of these Cyrex Lab tests for gut permeability and gluten cross-reaction?

[Guest guest]

Hello all,A doctor I spoke to recommended the following tests from Cyrex Labs:Array 2 & 4 (https://www.cyrexlabs.com/CyrexTestsArrays/tabid/136/Default.aspx)

The first is supposed to be an actual test for gut permeability and the second listed below is to test for gluten cross reaction to see if my son is reacting to the gluten-free grains he is eating in his diet.  Cyrex labs does not file insurance claims, so you'd have to pay up front and use the billing by Cyrex to get reimbursed.  The CPT codes are listed on their website and included below.  You can't order the tests without a doctor/healthcare professional prescription.

Has anyone heard of these tests or tried it?Thanks, Val
