title: Plasma free amino acid patterns in pregnancy: relationships to gestational age and applications to detection of fetal distress.
abstract: Data on free amino acids in serial samples of plasma from 15 pregnancies from 14 women have been compared to data from normal nonpregnant women by use of pattern-recognition program. The overall amino acid patterns were found to be a reproducible function of gestational age. Two samples from a woman with a pregnancy terminated by a spontaneous abortion were clearly resolved from all the other samples by this procedure.
