    What would be considered Normal level of Aldosterone?

    Hi All. I am looking at my blood test and it says Aldosterone: 4.3 and it shows normal range as: 0 -30 So what does that mean? How can the low range start from 0? So In order for Aldosterone to be flagged low it need to be a negative number? :) Thanks Peyt
