Patients with a suspected diagnosis of<unk>  are often screened with simple blood tests. Potassium levels, plasma aldosterone concentration and plasma renin activity are the three most useful in the first instance. Low aldosterone levels in the presence of high renin activity, often with low sodium, high potassium, is associated with primary<unk> . Secondary hypoaldersteronism may be suspected if renin activity is low with low aldosterone concentrations. The plasma aldosterone-to-renin ratio is calculated to determine if levels are sufficiently deranged to consider a diagnosis of<unk> . If screening test is suggestive, a more definitive diagnosis is made by performing a saline suppression test, ambulatory salt loading test, or fludrocortisone suppression test. Imaging to detect an Adrenocortical adenoma may also be considered.
