Use

Special Instructions
Not provided.
Limitations
False-positives are possible as other gastrointestinal disorders such as Crohn's disease, food protein intolerance, and post-infection malabsorption are known to induce circulating antigliadin antibody. Therefore, results should be interpreted in the context of clinical symptoms and other diagnostic tests.
