UNE-EN ISO 20186-1:2019

This International Standard recommends the handling, documentation, storage and processing of venous whole blood specimens intended for cellular RNA examination during the pre-examination phase before a molecular assay is performed. This International Standard covers specimens collected in venous whole blood collection tubes.This International Standard is applicable to any molecular in vitro diagnostic examination performed by medical laboratories. It is also intended to be used by laboratory customers, in vitro diagnostics developers and manufacturers, as well as institutions and commercial organizations performing biomedical research, biobanks, and regulatory authorities.Different dedicated measures need to be taken for stabilizing blood cell free circulating RNA and RNA in exosomes circulating in blood, which are not described in this International Standard.Different dedicated measures need to be taken for collecting, stabilizing, transporting and storing capillary blood as well as for collecting and storing blood by paper based technologies or other technologies generating dried blood. These are not described in this International Standard.This International Standard 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 International Standard.NOTE International, national or regional regulations or requirements may also apply to specific topics covered in this International Standard.
