ANTI TISSUE TRANSGLUTAMINASE IGA ANTIBODY

The Anti‑Tissue Transglutaminase IgA (tTG‑IgA) test is a blood serology assay that detects IgA antibodies directed against tissue transglutaminase, a sensitive marker used to screen for celiac disease. It measures immune response to gluten-induced intestinal injury and is performed on a venous blood sample with analysis in a certified laboratory. This home blood test in Dubai provides rapid, reliable screening to help clinicians decide on further evaluation such as endoscopic biopsy or dietary management.

• Anti‑Tissue Transglutaminase IgA (tTG‑IgA)
• Total Serum IgA (assessment for IgA deficiency)
• Anti‑Tissue Transglutaminase IgG (performed when IgA deficiency is suspected)

• Persistent gastrointestinal symptoms (chronic diarrhea, abdominal pain, bloating)
• Unexplained iron‑deficiency anemia or weight loss
• First‑degree relative with confirmed celiac disease
• Associated autoimmune conditions (type 1 diabetes, autoimmune thyroid disease)
• Prior to initiating a gluten‑free diet or when monitoring response to treatment

• Accurate, guideline‑aligned screening for celiac disease
• Home blood collection by trained phlebotomists across Dubai
• Certified laboratory analysis with fast turnaround of results
• Identifies need for further diagnostic steps (biopsy, specialist referral)
• Includes IgA assessment to reduce false‑negative results in IgA deficiency

• Remain on a gluten‑containing diet for at least 4–6 weeks prior to testing
• At‑home venous blood collection by a trained phlebotomist (no special fasting required)
• Inform the phlebotomist/clinic about immunosuppressive medications or prior celiac diagnosis
• Results reviewed by certified UAE lab; consult your physician for interpretation and next steps
