Summary

The 21-hydroxylase autoantibody (21-OH Ab) ELISA kit is intended for use by professional persons only, for the quantitative determination of 21-OH Ab in human serum. Autoimmune destruction of the adrenal cortex is the most common cause of Addison’s disease and autoantibodies to the adrenal specific enzyme steroid 21- hydroxylase are important markers of adrenal autoimmunity. This can be the case if the disease presents as Addison’s disease or as part of the autoimmune polyglandular syndromes (APS) type I or type II.
