Molecular in vitro diagnostic examinations. Specifications for pre-examination processes for circulating tumor cells (CTCs) in venous whole blood -- Isolated RNA
This document gives guidelines on the handling, storage, processing and documentation of venous whole blood specimens intended for the examination of human cellular RNA isolated from Circulating Tumor Cells (CTCs) during the pre-examination phase before a molecular examination is performed.
This document is applicable to molecular in vitro diagnostic examinations including laboratory developed tests performed by medical laboratories.
It is also intended to be used by:
This document does not cover the isolation of cellular RNA directly from venous whole blood containing CTCs. This is covered in EN ISO 20186-1.
This document does not cover the isolation of specific blood cells and subsequent isolation of cellular RNA therefrom.
RNA in pathogens present in blood is not covered by this document.
NOTE International, national or regional regulations or requirements can also apply to specific topics covered in this document.
