Maternal blood contamination of collected cord blood can be identified using DNA methylation at three CpGs

25 Jul 2017

Abstract excerpt

BACKGROUND: Cord blood is a commonly used tissue in environmental, genetic, and epigenetic population studies due to its ready availability and potential to inform on a sensitive period of human development. However, the introduction of maternal blood during labor or cross-contamination during sample collection may complicate downstream analyses. After discovering maternal contamination of cord blood in a cohort...
