Learnings from a Pilot External Quality Assessment (EQA) for cfDNA Extraction from Plasma

Efficient DNA extraction is critical to ensure sensitive and accurate detection of variants in cell-free DNA (cfDNA). EMQN has established a global pre-analytical EQA for extraction of cfDNA from plasma.

The objective is to evaluate the quantity and quality of eluted cfDNA and provide an external benchmark of participants‘ DNA extraction processes.
