Rapid detection of fetal aneuploidy using proteomics approaches on amniotic fluid supernatant

Abstract

Clinical proteomics analysis of AFS using magnetic beads-based sample preparation and MALDI-TOF-MS can be used as a rapid detection for fetal aneuploidies. With perfect sensitivity and negative predictive value of the two-step proteomics method, it may be used for rapid detection of aneuploid AFS immediately after amniocentesis. Further large-scale examinations are apparently needed to verify the clinical value of this rapid detection.
