How does the Celiac Disease Screening Test compare to the one performed in a doctor’s office?

While we can’t speak to other tests specifically, we can say that the Celiac Disease Screening Test follows a testing algorithm based on clinical guidelines and measures the antibodies tTg-IgA and total IgA, with reflex to DGP-IgG. 

The instruments and methods used by our laboratories are similar—and often exactly the same—as those used by a doctor’s office. Our at-home sample collection methods, like dried blood spot and saliva, have been widely used for decades.
