IgA Food Allergy Testing

Elevated IgA to specific foods is widely believed to be a sign of damage to the mucous membranes in the gut. Individuals with Crohn’s disease or ulcerative colitis, or even those with suspected leaky gut may benefit from an IgA blood test for food reactions. IgA is produced in the greatest quantity in a day. IgA antibodies are the first line of defence against suspected disease-causing agents like viruses and bacteria.

IgA antibodies are found in areas of the body such the nose, breathing passages, digestive tract, ears, eyes, and vagina. IgA antibodies protect body surfaces that are exposed to outside foreign substances. This type of antibody is also found in saliva, tears and blood. About 10% to 15% of the antibodies present in the body are IgA antibodies. A small number of people do not make IgA antibodies. It is recommended that IgA allergy testing is only performed for infants greater than 18 months of age.
