ANTI TISSUE TRANSGLUTAMINASE IGG ANTIBODY

The Anti Tissue Transglutaminase IgG Antibody test measures IgG class autoantibodies directed against tissue transglutaminase, an enzyme involved in intestinal tissue repair. Detection of anti‑tTG IgG helps identify individuals at increased risk of coeliac disease, particularly when IgA deficiency or equivocal IgA serology limits the value of standard anti‑tTG IgA tests. This home blood test offers convenient sample collection across Dubai and the UAE with laboratory analysis and fast electronic reporting.

A positive anti‑tTG IgG result suggests immune reactivity to gluten and should prompt clinical correlation and follow‑up with a gastroenterologist; definitive diagnosis of coeliac disease typically requires integration of serology, clinical findings and, when indicated, intestinal biopsy. The test is suitable for adults and children when performed while the patient is on a gluten‑containing diet, and results should always be interpreted alongside total IgA status and other relevant investigations.
