Special Instructions
Not provided.
Limitations
This test was developed by Labcorp and has not been cleared or approved by the FDA. Serological markers like tTG IgA and EMA IgA have shown sensitivity below 50% for detecting villous atrophy in patients on a GFD. There is a significant need for more accurate monitoring methods for non-response to a GFD. While the test can indicate gluten exposure, it cannot account for all factors affecting gluten sensitivity.
