This document provides recommendations and requirements on the handling, storage, processing and documentation of venous whole blood specimens intended for circulating cell free DNA (ccfDNA) examination during the pre-examination phase before an analytical test is performed. This document covers specimens collected in venous whole blood collection tubes.
This document 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, biobanks, institutions and commercial organizations performing biomedical research, and regulatory authorities.
Different dedicated measures are taken for stabilizing blood genomic DNA, which are not described in this document. Blood genomic DNA is covered in ISO 20186-2.
Different dedicated measures are taken for preserving DNA in circulating exosomes, which are not described in this document.
NOTE ccfDNA obtained from blood by the procedures cited in this document can contain DNA originally present in exosomes[8][9].
DNA in pathogens present in blood is not covered by this document.
Molekularanalytische in-vitro-diagnostische Verfahren - Spezifikationen für präanalytische Prozesse für venöse Vollblutproben - Teil 3: Aus Plasma isolierte zirkulierende zellfreie DNA (ISO 20186-3:2019)
Dieses Dokument enthält Empfehlungen und Anforderungen für die Handhabung, Lagerung, Verarbeitung und Dokumentation von venösen Vollblutproben, die für die Untersuchung zirkulierender zellfreier DNA (ccfDNA) vorgesehen sind, während der präanalytischen Phase vor Beginn einer analytischen Prüfung. Dieses Dokument behandelt Untersuchungsmaterial, das in Blutentnahmeröhrchen für venöses Vollblut entnommen wurde.
Dieses Dokument gilt für alle molekularen in vitro diagnostischen Untersuchungen, die in medizinischen Laboren durchgeführt werden. Es ist außerdem auch für die Verwendung durch Labor Kunden, Entwickler und Hersteller von In vitro Diagnostika, Biobanken, Einrichtungen und kommerzielle Organisationen, die in der biomedizinischen Forschung tätig sind, sowie durch Aufsichtsbehörden vorgesehen.
Zur Stabilisierung genomischer DNA aus Blut werden andere spezielle Maßnahmen getroffen, die nicht in diesem Dokument beschrieben sind. Genomische DNA aus Blut wird in ISO 20186 2 behandelt.
Zur Erhaltung der DNA in zirkulierenden Exosomen werden andere zweckbestimmte Maßnahmen ergriffen, die in diesem Dokument nicht beschrieben werden.
ANMERKUNG ccfDNA, die mit den in diesem Dokument vorgeschlagenen Verfahren aus Blut gewonnen wurde, kann DNA enthalten, die ursprünglich in Exosomen vorlag [8], [9].

Analyses de diagnostic moléculaire in vitro - Spécifications relatives aux processus préanalytiques pour le sang total veineux - Partie 3: ADN libre circulant extrait du plasma (ISO 20186-3:2019)
Le présent document fournit des recommandations et des exigences sur la manipulation, le stockage, le traitement et la documentation des prélèvements de sang total veineux destinés à l'analyse de l'ADN libre circulant (ADNlc) durant la phase préanalytique précédant la réalisation d'un essai analytique. Le présent document concerne les échantillons primaires prélevés dans des tubes de prélèvement de sang total veineux.
Le présent document s'applique aux analyses de diagnostic moléculaire in vitro réalisées par des laboratoires de biologie médicale. Il est également destiné à être utilisé par des clients de laboratoires, des développeurs et fabricants de l'industrie du diagnostic in vitro, ainsi que par des biobanques, des institutions et des organismes commerciaux spécialisés en recherche biomédicale, de même que des autorités de réglementation.
Des mesures spécifiques différentes, non décrites dans le présent document, sont prises pour stabiliser l'ADN génomique sanguin. L'ADN génomique sanguin est couvert par l'ISO 20186-2.
Des mesures spécifiques différentes, non décrites dans le présent document, sont prises pour préserver l'ADN des exosomes circulants.
NOTE L'ADNlc extrait du sang à l'aide des protocoles cités dans le présent document est susceptible de contenir de l'ADN présent à l'origine dans les exosomes[8][9].
L'ADN des pathogènes présents dans le sang n'est pas couvert par le présent document.
Molekularne diagnostične preiskave in vitro - Specifikacije za predpreiskovalne procese za vensko polno kri - 3. del: Iz plazme izolirana cirkulirajoča brezcelična DNK (ISO 20186-3:2019)
Ta mednarodni standard vsebuje priporočila za obravnavo, dokumentiranje, shranjevanje in obdelavo vzorcev venske polne krvi, namenjenih za analizo cirkulirajoče brezcelične DNK (ccfDNA) med predpreiskovalno fazo, preden se izvede molekularni preskus. Ta mednarodni standard zajema vzorce, ki so zbrani s cevkami za zbiranje venske polne krvi. Ta mednarodni standard se uporablja za molekularne diagnostične preiskave in vitro, vključno z laboratorijsko razvitimi preskusi, ki jih izvajajo v medicinskih laboratorijih. Uporabljali naj bi ga tudi uporabniki laboratorijev, razvijalci in proizvajalci diagnostike in vitro, navezuje pa se tudi na institucije in komercialne organizacije, ki izvajajo biomedicinske raziskave, biobanke ter regulativne organe. Profili cirkulirajoče brezcelične DNK se lahko znatno spremenijo po odvzemu krvi od darovalca (npr. sprostitev genomske DNK iz belih krvnih celic, razpad ali sprememba količine cirkulirajoče brezcelične DNK). Zato je treba sprejeti posebne ukrepe za pridobivanje vzorcev krvi dobre kakovosti za analizo in shrambo cirkulirajoče brezcelične DNK. Za ohranjanje krvne genomske DNK je treba uporabiti drugačne namenske ukrepe, ki niso opisani v tem mednarodnem standardu. Krvna genomska DNK je opisana v standardu ISO 20185-2, Molekularne diagnostične preiskave in vitro – specifikacije za predpreiskovalne procese za vensko polno kri - 2. del: Iz genoma izolirana DNK OPOMBA: cirkulirajoča brezcelična DNK iz krvi, pridobljena s postopki, ki jih predlaga ta dokument, lahko vsebuje DNK iz eksosomov. Patogena DNK v krvi ni zajeta v tem mednarodnem standardu. Za ohranjanje DNK v cirkulirajočih eksosomih je treba uporabiti drugačne namenske ukrepe, ki niso opisani v tem mednarodnem standardu. OPOMBA: Za določene teme, ki so zajete v tem mednarodnem standardu, lahko veljajo tudi mednarodni, nacionalni ali regionalni predpisi ali zahteve.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
