The full answer
It strongly suggests celiac disease, but isn't a final diagnosis on its own
A positive tTG-IgA result means the immune system is producing antibodies consistent with celiac disease, but doctors generally confirm the diagnosis with an endoscopy and biopsy before recommending a lifelong gluten-free diet — since a definitive diagnosis matters for long-term treatment decisions.
What to expect next
Keep eating gluten normally until the biopsy is complete — see why stopping gluten early can interfere with testing.
