Tissue transglutaminase antibody IVD, kit, enzyme immunoassay (EIA)

Tissue transglutaminase antibody IVD kits use enzyme immunoassay (EIA) to detect antibodies (IgA or IgG) linked to celiac disease or gluten sensitivity. These tests analyze patient serum or plasma to help diagnose or monitor autoimmune-related gastrointestinal conditions by identifying specific immune responses.

These devices are typically regulated as in vitro diagnostics (IVDs) and may require validation for clinical accuracy. They are supplied as reagent kits, often including controls and calibration standards, and are used exclusively in laboratory settings by trained personnel.
