Antiadrenal Antibodies, Quantitative
Also known as: Adrenal Antibodies, Serum, Antiadrenal Cortex Antibodies
Use
Evaluate for adrenal insufficiency and Addison disease. Serum antibodies to adrenal cortical cells, usually of all three zones, are seen in 60% of patients with idiopathic Addison disease. They are present in only 5% to 17% of patients with tuberculous, fungal, or metastatic destruction of the adrenals, and in 38% of unclassified cases. Antiadrenal antibodies are also present in such apparently unrelated processes as idiopathic hypoparathyroidism (28% of cases) and Hashimoto disease (7%).

Limitations
This test has a defined reference range, with negative results indicated by titers of less than 1:10. As with all laboratory tests, the potential for false negatives or positives exists, and results should be interpreted in the context of the patient's clinical condition and history.
