A rapid dried-filter paper plasma-spot analytical method was developed to quantify organic acids, amino acids, and glycines simultaneously in a two-step derivatization procedure with good sensitivity and specificity. The new method involves a two-step trimethylsilyl (TMS) - trifluoroacyl (TFA) derivatization
