My daughter is 2 1/2 months old. Her last blood test two weeks ago came back with low Renin level (73 versus normal range 250 - 2300). Her Renin actually has been on a low level for about a month. Her regular endo is on vacation. The other endo in the same group doesn’t want to make adjustment of the dosage of her Florinef until her regular endo comes back. Doesn’t anyone know what kind of harm it can cause if the Renin remains low for a extended period of time? Thanks.
