Simultaneous analysis of galactose and other biomarkers (phenylalanine and 17α-OHP) for the newborn screening test. a Mass spectra of phenylalanine and 17α-OHP in PCB. b Mass spectra of OPD reaction products of mixtures with constant concentrations of phenylalanine and 17α-OHP; the concentration of galactose was changed in the range around the cutoff value. c Mass spectra of OPD reaction products of mixtures with constant concentrations of galactose and 17α-OHP; the concentration of phenylalanine was changed in the range around the cutoff value. d Mass spectra of OPD reaction products of mixtures with constant concentrations of phenylalanine and galactose; the concentration of 17α-OHP was changed in the range around the cutoff value
