Casandra
Casandra Test Code LC67059Version 1 (DRAFT)
Performing Lab
Celiac Antibodies Profile tTG IgA, tTG IgG, DGP IgA, DGP IgG, and Total IgA
Also known as: Deamidated Gliadin Antibodies (DGP), Gliadin, Tissue Transglutaminase (tTG)
Clinical Use
Order TestUse
Aid in the diagnosis of gluten-sensitive enteropathies
Special Instructions
Not provided.
Limitations
The test is highly specific for gluten-sensitive enteropathy, as endomysial IgA antibodies demonstrated in the test are noted to have over 99% specificity for this condition. However, for conclusive diagnosis, additional factors and confirmatory tests could be required based on individual patient conditions and symptoms.
