The extended neonatal screening service by tandem mass spectrometry (LC MS/MS) allows the identification of 26 metabolites (13 amino acids and 13 acylcarnitine derivatives). These metabolites in specific numbers and proportions allow the evaluation of 32 genetic metabolic diseases. Blood samples collected on filter paper during the first 48-72 hours of the newborn’s life are used for this determination. A result that is outside the normal range raises a suspicion that requires confirmation by additional and diagnostic tests.
