21-Hydroxylase

The RSR 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.
