A New Approach To Dried Blood Spot Analysis For Newborn Screening Using High Resolution Liquid Chromatography Tandem Mass Spectrometry, John H. Miller Iv

Theses and Dissertations

The primary purpose of newborn screening is to quickly identify children that are at risk of having a specific disorder in order to start treatment, prevent early death and reduce the chances of permanent physical or mental damage. The current and widely accepted approach used for identification of metabolism disorders involves a flow injection analysis with mass spectrometry detection of acylcarnitines and amino acids. Although this approach is widely accepted and has shown to be sufficient for identification of multiple metabolism disorders the method is not fully quantitative and results often have to be confirmed by second-tier tests. The primary …
