Diagnostic Use

In the diagnosis of primary aldosteronism or similar forms of hypokalaemic hypertension.

In localising the aldosterone adenoma by adrenal vein catheter sampling.

In certain types of adrenocortical insufficiency - particularly hypoaldosteronism or other salt wasting disease associated with abnormalities of steroid biosynthesis.

In cases of hypokalaemia query cause, eg Bartters syndrome.

Hyporeninaemic syndromes producing hyperkalaemia.

Note: Renin measurement is indicated in most of the above applications.

Interpretation of adrenal vein aldosterone levels require simultaneous central (adrenal vein) and peripheral sampling for cortisol and aldosterone levels. Constant low dose ACTH stimulation may assist interpretation of results. Please consult with an Endocrinologist before undertaking adrenal vein sampling tests. Remember that prior drug use (eg. spironolactone, amiloride, ACE inhibitors, AT2 antagonists, beta blockers and diuretics) may affect interpretation of aldosterone and renin results.
