Brief summary

This research uses the Liquid Chromatography coupled to tandem Mass Spectrometry (LC-MS / MS) technique on dried blot spot samples for the neonatal screening of congenital adrenal hyperplasia. The main objective of this study is to demonstrate that this technique allow dosage of adrenal steroids on dried blot spot samples as efficiently and with the same sensitivity than the current technic on a cohort of 132 newborns aged 2 to 5 days, with a gestational age greater than or equal to 30 weeks of amenorrhea.
