Inborn errors of metabolism (IEM) are genetic defects involving disorders of enzyme activities in which the toxic substances accumulates and causes neurologic manifestations. This may lead to death or permanent disability of the child. Newborn screening (NBS) is the detection and early intervention is pre-symptomatic newborns with inborn errors of metabolism to prevent adverse outcomes of the disorder. NBS is done by analysis of biomarkers in blood by a spectrum of analytical methods. The introduction of tandem mass spectrometry for newborn screening is a technological breakthrough which is used across the globe nowadays. The power of NBS is enormously enhanced by tandem mass spectrometry (MS/MS) by the ability to analyze several metabolites simultaneously in the same dried blood spot (DBS) with increased sensitivity and specificity. NBS programs tend to focus on three groups of metabolites: amino acids fatty acid oxidation intermediates and short chain organic acids.
