Abstract:Liquid profiling based on circulating tumor DNA (ctDNA) extracted from blood has become a powerful diagnostic approach in oncology. Making ctDNA analysis broadly available requires shipping whole blood to a clinical laboratory while ensuring cell-free DNA (cfDNA) and blood cell integrity to prevent dilution of ctDNA with cellular genomic DNA. Since standard EDTA blood collection tubes cannot retain this integrity for a prolonged time, several laboratories have proposed Streck Cell-Free DNA blood collection tub… Show more
