Plasma and urine 18-hydroxycortisol ('18-OHF') measurements are helpful to discriminate primary hyperaldosteronism (Conn's syndrome) caused by adrenal hyperplasia (normal 18-OHF) from adrenal adenoma or glucocorticoid suppressible hyperaldosteronism ( raised 18-OHF). We have developed DELFIA time-resolved fluorescence assays for 18-OHF as a second-line biochemical investigation for patients with raised plasma aldosterone/ renin ratios. Following ether extraction, test samples ...
