Is IgA elevated in celiac disease?
However, 3 percent of patients with celiac disease have IgA deficiency. Therefore, if the serum IgA tTG result is negative but clinical suspicion for the disease is high, a serum total IgA level may be considered.
What is the function of IgA?
IgA accounts for more than two-thirds of the body’s total immunoglobulin production. IgA serves as an important first-line barrier limiting the access of intestinal antigens to the gut mucosa, controls the intestinal microbiota and dampens pro-inflammatory immune responses.
