Dilute urine may be considered to have an isotonic portion and an electrolyte-free
water portion. The proportions of electrolytes-free water and isotonic can be measured
by the ratio of effective solutes (principally sodium and potassium, with associated
anions) between the plasma and the urine [
[1]
,
[2]
]. Restriction of water intake to less than the amount of electrolyte-free water excreted
will cause serum sodium to rise.Keywords
