title: Free amino acids in plasma throughout pregnancy.
abstract: Plasma amino acid analyses on 27 amino acids in serial samples from 15 pregnancies in 14 patients are reported. Variations of amino acid levels with gestational age are reported both for absolute amino acid levels and for levels normalized to total amino acids, with a t test used to determine which amino acids vary significantly. The extent to which individual results differ from the means is indicated. Correlation and regression analyses were done for each amino acid vs. every other amino acid and for each amino acid vs. gestational age. Significant differences were found in amino acid results for plasma from an individual in whom pregnancy resulted in spontaneous abortion.
