Aldosterone was 2 ng/dl (fasted, early morning, upright) is this normal or low? does it warrant further testing? cortisol was high/normal 22.2 mcg/dl

More history: I don't know much about your history or what has caused you to have this testing in the first place so I won't be of much help, BUT the aldosterone level is low and may warrant further testing for Cushing's syndrome, 17-alpha-hydroxylase deficiency,Liddle's syndrome,ectopic ACTH syndrome, or mutations of your mineralcorticoid receptors. You need to talk to your doctor for more direction.
