Secretory Immunoglobulin A (sIgA)

SIgA is an important indicator of digestive immune function. Chronic intestinal infections (due to bacterial, yeast or parasites), food sensitivities, aging, antibiotics, medication and stress all decrease sIgA levels. Low levels can lead to recurrent infections and food intolerances. Very low levels of this important antibody class have also been observed in autistic spectrum disorders.
