This Technical Specification provides recommendations on the handling, documentation and processing of blood specimens intended for circulating cell free DNA (ccfDNA) analysis during the pre-examination phase, namely before a molecular examination is performed. This Technical Specification is applicable to molecular in vitro diagnostic methods (for example, in in vitro diagnostics laboratories, laboratory customers, in vitro diagnostics developers and manufacturers, institutions and commercial organizations performing biomedical research, biobanks and regulatory authorities). ccfDNA in blood can change drastically prior and during sampling (for example ccfDNA fragmentation, ccfDNA quantity, release of genomic DNA from cells in white blood cells). Therefore, special measures for quality assurance of blood specimens for the following ccfDNA analyses shall be taken.
