The tissue transglutaminase IgA antibody test, or TTG-IgA for short, is a vital diagnostic tool that is mostly used to identify celiac disease, an autoimmune condition in which eating gluten damages the small intestine. IgA antibodies against tissue transglutaminase are measured by this test, and they are usually higher in those who have active celiac disease.

The TTG-IgA test is mostly used to diagnose celiac disease, although its significance for heart diagnosis (HHD) is becoming more widely acknowledged. Studies have demonstrated that celiac disease can affect cardiovascular health among other systemic impacts. For example, those with untreated celiac disease are more likely to experience difficulties connected to inflammation, which can affect the cardiovascular system and raise the risk of
