Mid-infrared (MIR) metabolic fingerprinting of amniotic fluid: A possible avenue for early diagnosis of prenatal disorders?

► First profiling study of amniotic fluid by MIR and multivariate analysis. ► MIR/MIR and MIR/NMR correlation for IR assignment of disease-related metabolites. ► MIR profiling changes related to fetal malformations and preterm delivery. ► Putative interpretation of MIR signatures of fetal malformations/preterm delivery.
