Test indications

 

Anti-adrenal antibodies are found in 60% of patients with idiopathic hypoadrenalism where they are directed against the enzyme 21-hydroxylase, and in 90% of those with hypoadrenalism in association with ovarian failure (Autoimmune Polyglandular Syndrome-1, APS-1) where they react with 17-hydroxylase and the side chain cleaving enzyme complex involved in steroid bio-synthesis. They are found in <0.1% of the normal population. The titre of antibody is of no significance, and so is not measured. As the adrenal gland atrophies the antibodies may disappear so sequential follow-up is not useful.
