The NADAL® Celiac Disease tTG & Gliadine Test
It's a rapid immunoassay for detection of anti-gliadin antibodies and IgA against human tissue transglutaminase (tTG), the main autoantigen recognized by anti-endomysial antibodies, in whole blood samples.
The NADAL® Celiac Disease tTG & Gliadine Test is designed for professional use only and is especially useful in the case of pediatric patients (up to 16 years old).
Reagents and material supplied:
-
10 NADAL® Celiac Disease tTG & Gliadine test cassettes
-
10 Collection pipettes (20 μl)
Test time: 10 min
Performance characteristics:
Specificity and sensitivity of the NADAL® Celiac Disease tTG & Gliadine Test considering anti-tTG IgA and anti-gliadin antibodies is assesed by comparison with: Eurospital Eu-tTG IgA; Gliatest S IgA Chromo tests and conventional ELISA assay.
