Assessment of Maternal Cell Contamination in Prenatal Samples by Quantitative Fluorescent PCR (QF-PCR)

Methods Mol Biol. 2019:1885:117-127. doi: 10.1007/978-1-4939-8889-1_8.

Abstract

When biopsying a fetal tissue like chorionic villi or amniotic fluid, there is a chance of getting some maternal material that could contaminate the fetal specimen and might lead to a misdiagnosis. Thus, all prenatal samples should be subjected to testing for maternal cell contamination. This is done using quantitative fluorescent PCR (QF-PCR) of short tandem repeat (STR) markers.
