medical history, physical exam, and lab tests
often point to celiac disease. The diagnosis is confirmed with a small
biopsy collected during an
endoscopy, where a small tube is guided
down a person's throat to the small intestine.
Tests for celiac disease should be done when you or your child is still eating a diet that includes gluten. If you have already started a gluten-free diet before these tests are done, the doctor may suggest that you or your child eat a certain amount of gluten before the tests.
When Jennifer Esposito was diagnosed with celiac disease three years ago, the actress was shocked and relieved. "It was hard, but it was also the day I realized the person I once knew as 'me' was gone," says Esposito, 39, who plays detective Jackie Curatola on the CBS hit police drama Blue Bloods.
Misleading advice and a delayed diagnosis cost Esposito precious "life" time as she searched for the reasons behind a litany of unexplained ailments, she says. Now she's determined to save others from...
Celiac disease triggers the
immune system to produce certain
antibodies. Blood tests that find and measure these
IgAtTG: Immunoglobulin A (IgA) anti-tissue
transglutaminase (tTG) antibody.
IgAEMA: Immunoglobulin A (IgA) antiendomysial antibody (EMA).
A biopsy taken during an
upper gastrointestinal endoscopy may be done to
confirm celiac disease after antibodies have been found. Sometimes a biopsy
detects celiac disease when a person is being tested for another
If the biopsy shows signs of celiac disease
(such as abnormal villi and inflammation in the
small intestine), a
gluten-free diet will be recommended.
A diagnosis of
celiac disease is confirmed if the diet makes symptoms
go away and if antibody tests become normal.
