Clinical Info
Diagnosis of disorders of the renin-angiotensin-aldosterone system. Normal serum levels of aldosterone are dependent on the sodium intake and whether the patient is upright or supine. High sodium intake will tend to suppress serum aldosterone, whereas low sodium intake will elevate serum aldosterone. The reference interval for serum aldosterone are based on normal sodium intake.
