title: Methods for determining the protein requirement of infants.
abstract: Although there is no clearly preferred method to determine the precise protein requirement of infants, a variety of techniques have been employed to provide a reasonable approximation of this variable. These approaches include anthropometric measurements, the determination of nitrogen balance, the estimation of rate of whole body protein synthesis and catabolism by the administration of amino acids labeled with stable isotopes, and the determination of serum concentrations of certain proteins and amino acids.
