Dietary Antigens Specific IgA

The Dietary Antigen Specific Secretory IgA (sIgA) test uses saliva to assess one of the earliest responses to 88 foods.

SIgA is the dominant immunoglobulin secreted across mucosal surfaces, making up a large portion of our immune system, and is often described as our first line of defence against microbial invasion. It is critical in developing immune tolerance and serves to influence other branches of the immune system such as IgG and IgE.

When sIgA increases to specific foods, levels may rise initially, and it can be associated with gut-based inflammation.

This can also be a useful follow-up profile to a stool profile that may show raised sIgA but does not report a bacterial or viral trigger.
