  • Title: Urinary nitrogen excretion as related to dietary protein in pregnant women.
    Author: Zlatnik FJ.
    Journal: J Reprod Med; 1979 Mar; 22(3):128-32. PubMed ID: 439087.
    Abstract:
    The amount of urea in the urine acutely decreases when dietary protein is restricted. This change in urinary urea nitrogen can be represented satisfactorily by the urea nitrogen/total nitrogen (UN/TN) ratio or the UN/creatinine nitrogen (UN/CN) ratio. These determinations are apparently effective tools for simply and objectively describing the recent protein intake of pregnant women.
