Genetic test to rule out Celiac Disease?
My son tested negative on the blood test for Celiac's Disease.
On one of our trips to the Urgent Care when my son thought he was going to pass out from the pain, a nurse told us that the blood test could be false negative but what he needed was the genetic test (her whole family has Celiac's Diease, tested negative on blood test, but positive on genetic test).
Thank you,
Mary
