    Low renin and potassium, high sodium, normal aldosterone - adds up to...?

    During a recent ER visit the resident treating me noticed I have a 10+ year history of low potassium (3.2-3.8; ref 3.8-5.1) and normal/high sodium (144-149; ref 135-145). I've had HBP for about 5 years, taking 20mg lisinopril qd with good results.

    Aldosterone level was 8.8 ng/dL (ref 0.0-30.0) and renin was 0.55 ng/mL/hr (ref 1.31-3.95). Cortisol was 16.5 ug/dL (ref 4.4-22.0).

    My PCP “isn't really sure” what these results mean, and has referred me to an endocrinologist... in late May.

    I'm beginning to suffer from google-induced (mis)information-overdose paranoia.

    Does anyone have an idea what these results might mean, or a good reference web site?

    Thanks!

    Oh, forgot-

    41 y.o. male; ER visit was for a kidney stone. Health history other than stage 1 hypertension (controlled) is remarkably unremarkable.

    Thanks again...

    Perhaps your kidney stone could have thrown off your kidney function a bit, perhaps you should ask for a follow-up test to see if things have normalized.

    You might try looking up renin aldosterone angiotensin system (raas). That should help with about half of your question. Basically it's how your kidneys try to control your bp.

    I just did it because I got my test results for aldosterone and renin. I was a little low on each one.
