Celiac blood panel
Informed by recognized medical guidance
Overview
A celiac blood panel is a group of blood tests that look for certain antibodies your body makes when you have celiac disease. Celiac disease is an autoimmune condition — meaning your immune system mistakenly attacks your own body — triggered by eating gluten, a protein found in wheat, barley, and rye.
Key facts
- The blood panel checks for antibodies like tTG-IgA and total IgA.
- It is often the first test a doctor orders if they suspect celiac disease.
- A positive result usually leads to a follow-up test called an endoscopy with biopsy to confirm the diagnosis.
Celiac disease affects about 1 in 100 people worldwide, but many remain undiagnosed. The blood panel helps identify those who may have it.
Anyone can develop celiac disease, but it is more common in people with a family history of the condition or certain other autoimmune disorders, such as type 1 diabetes.
