| Title | Specifications for pre-examination processes for circulating tumor cells (CTCs) in venous whole blood -- Part 1: Isolated RNA |
| Work Item Number | 00140155 |
| Abstract/Scope | This document gives guidelines on the handling, storage, processing and documentation of human venous whole blood specimens intended for the examination of RNA isolated from circulating tumour cells (CTCs) during the pre-examination phase before a molecular examination is performed. This document is applicable to molecular in vitro diagnostic examinations performed and/or developed by medical laboratories, in vitro diagnostics developers and manufacturers, institutions and commercial organizations performing biomedical research. It is also intended to be used by laboratory customers including health institutions requesting examinations for their patients as well as biobanks and regulatory authorities. This document does not cover the isolation of cellular RNA directly from venous whole blood containing CTCs. This is covered in ISO 20186-1, Molecular in vitro diagnostic examinations - Specifications for pre-examination processes for venous whole blood – Part 1: Isolated cellular RNA. This document does not cover the isolation of specific white blood cells and subsequent isolation of cellular RNA therefrom. This document does not cover pre-analytical workflow requirements for viable CTC cryopreservation and culturing. NOTE 1 The requirements given in this document can also be applied to other circulating rare cells (e.g. fetal cells). NOTE 2 International, national or regional regulations or requirements can also apply to specific topics covered in this document. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
