Fetal derived cell-free DNA (cfDNA) is a key analyte for determining fetal RHD status in plasma samples. Due to the very low concentrations of cfDNA found in plasma, robust pre-analytical methods are needed to enable sensitive detection in downstream applications and reliable results.

Devyser and QIAGEN are collaborating to evaluate automated bead-based purification of cfDNA from plasma samples on the QIAsymphony SP instrument for non-invasive fetal RHD detection.

We determined that using the QIAGEN dedicated kit for cfDNA extraction and the Devyser RHD qPCR assay successfully allowed RHD determination from 1ml plasma.

**Results from the joint study will be presented at the 5th International Meeting on Cell-Free DNA in Copenhagen, May 25 – 26 2023. **
