Celiac Disease Diagnosis
Celiac disease diagnosis pairs tTG-IgA blood work with biopsy while you still eat gluten—starting GF early can hide results and delay proper care.
Celiac disease diagnosis combines blood tests—often tissue transglutaminase IgA with total IgA—and small-intestinal biopsy showing villous damage while still eating gluten. Starting a gluten-free diet before testing can yield false negatives and delay care.
Genetic markers support risk context but do not diagnose alone.
Common questions
-
Can you diagnose celiac without a biopsy?
Some guidelines allow serology-only pathways in specific pediatric cases; most adults still need biopsy or structured specialist rules. Do not self-diagnose from online symptom quizzes alone.
