Fecal sIgA is the most abundant class of antibodies found in the intestinal lumen. The immune tolerance of the intestinal mucosa can be evaluated using the concentration of fecal sIgA. A deficiency of sIgA points to diminished activity of the mucosa immune system, whereas increased sIgA values indicate increased activity and local inflammation of the intestinal mucosa.

The IDK® sIgA ELISA is an enzyme immunoassay intended for the quantitative determination of secretory IgA (sIgA) in saliva and stool. FDA Class 1 Exempt. For In Vitro Diagnostic Use. Health Canada Licensed.

The IDK® sIgA ELISA is compatible with our IDK Extract® Stool Sample Preparation System.


  • Proof of an imbalanced immunological barrier of the intestinal mucosa
  • Detection of autoimmune diseases

If your lab is testing at high volumes, the IDK® sIgA ELISA is also available in a customized bulk pack (20 plates).
