Performing Lab
Endomysial IgG Antibody Screen and Titer
Clinical Use
Order TestUse
The endomysial IgG antibody test serves as a secondary autoantibody assay, particularly used when total serum IgA is low or when clinical suspicion for celiac disease or dermatitis herpetiformis is high despite negative IgA‑EMA or tTG antibodies; it helps assess gluten‑sensitive enteropathy in these contexts.
