The art of obtaining a high yield of cell-free DNA from urine
07 Jul 2021

Although urine is becoming increasingly important in the liquid biopsy field, the detection of circulating cell-free DNA (cfDNA) in urine samples remains a challenge.

Using more tumor material to increase the sensitivity is often compromised by the degradation of cfDNA and/or the contamination with genomic DNA derived from healthy cells. Hence, the optimization of pre-analytical conditions, especially in urine samples, is essential in order to obtain samples with a high cfDNA quality and yield.

Elien Augustus from the University of Antwerp investigated several pre-analytical conditions in order to establish good practice guidelines. Urine samples from healthy volunteers and cancer patients were collected and processed differently according to specific pre-analytical conditions.

In this webinar, Augustus will demonstrate findings from this research, noting the variation of cfDNA content within one urine sample, the most optimal time point for urine collection, the effect of use of preservatives, and the most appropriate centrifugation protocol.
