Casandra Test Code LC48375Version 1 (DRAFT)
Performing Lab
Celiac Antibodies tTG IgA, EMA IgA, Total IgA With Reflex to tTG IgG
Also known as: Endomysial Antibodies, Tissue Transglutaminase (tTG) Antibodies
Clinical Use
Order TestUse
Aid in the diagnosis of gluten-sensitive enteropathies
Special Instructions
Not provided.
Limitations
While the test is highly specific for celiac disease, a negative result does not completely rule out the disease. Antibody levels might be lower or undetectable if the patient is on a gluten-free diet at the time of testing. Other conditions, such as autoimmune diseases, may also contribute to the presence of these antibodies.
