Interpretive Data:
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 intervals for serum aldosterone are based on normal sodium intake.
Comments:
If an upright sample is collected, patient should be upright (seated or standing) for at least two hours.
Methodology:
Radioimmunoassay
