21 Hydroxylase Ab’s


SKU: 21HA Category:


Chronic primary adrenal insufficiency (Addison disease) is most commonly caused by the insidious autoimmune destruction of the adrenal cortex and is characterized by the presence of adrenal cortex autoantibodies in the serum. Autoantibodies to steroid 21-hydroxylase are a major component of adrenal cortex antibodies and are characteristic of autoimmune Addison’s disease. 21-hydroxylase antibodies are now tested instead of adrenal antibodies.

This test measures 21 Hydroxylase Antibodies in the blood sample.
