Cyrex Lab Testing Array 4
In cross-reactivity, the body may mistake another food for gluten and react accordingly. Array 4 tests for 24 different foods that may be causing cross-reactivity or are newly introduced to the diet or over-consumed favorites.
One of the most frustrating scenarios for both the practitioner and the patient is when a gluten-free diet fails to have any effect on a person who seems so clearly gluten sensitive. Newer research shows this may be due to cross-reactivity.

Clinical Use
- Identify additional dietary proteins to which the Non-Celiac Gluten Sensitivity (NCGS) or Celiac Disease (CD) patient is sensitized
- Detect cross-reactions in the patient non-responsive on a gluten-free diet
- Categorize the 1-in-2 NCGS or CD patient who is also sensitive to dairy products
Recommended for Patients Who

- Have Non-Celiac Gluten Sensitivity or Celiac disease
- Are experiencing limited improvements or are non-responsive on a gluten-free diet
- Have gut dysbiosis, which appears to be resistant to standard therapy
