Gliadin peptide+Tissue transglutaminase Ab.IgA+IgG

This test detects antibodies (IgA and IgG) against gliadin and tissue transglutaminase, key markers for celiac disease screening. When people with celiac disease consume gluten, their immune system attacks intestinal tissue and produces these antibodies. A positive result strongly suggests celiac disease and warrants further testing with small intestinal biopsy for confirmation. Early detection is important because untreated celiac disease can cause intestinal damage, nutrient malabsorption, and long-term complications including osteoporosis and increased infection risk.
