Tissue Transglutaminase (tTG) Antibodies (IgA, IgG)
Get clarity on your body's reaction to gluten with the Tissue Transglutaminase Antibodies (IgA, IgG) test. This serology profile measures two key antibodies your immune system produces when it mistakes gluten as a threat. Elevated levels of tTG IgA or IgG are strongly consistent with a diagnosis of Celiac Disease or Dermatitis Herpetiformis, especially when IgA deficiency is a concern. It is the preferred initial screening test for individuals experiencing Celiac symptoms or those with a high-risk family history. Take this crucial step toward understanding your health and managing gluten sensitivity effectively.
