Aldo of 10: In order to be able to interpret an aldo level in the urine you must know your salt intake measured in that 24 hr urine. If urine Na is low then this is a low urine aldo as low salt in diet increases aldo. If your salt intake is high then this may be a normal urine aldo. You must ask the lab that did the test for their normal range based on salt intake. Has K ever been low? This may lower aldo ...Read more

Is it possible for aldosterone to make urine hypoosmiotic and concentrated?

Physiology: Hi. Aldosterone is primarily there to regulate renal handling of sodium, potassium, and acid. Urine concentration/osmolality is more a function of anti-diuretic hormone (ADH) regulating tubular luminal (phenobarbital) water channels and the ambient solute gradient in the loop of Henle. Water follows sodium in general, but the kidneys place quite a degree of regulation on this, so aldo has trivial effect on conc. ...Read more

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

You need to talk to your doctor for more direction. ...Read more
