Molecular in vitro diagnostic examinations - Specifications for pre-examination processes for venous whole blood - Part 2: Isolated genomic DNA (ISO 20186-2:2019)
This document gives guidelines on the handling, storage, processing and documentation of venous whole blood specimens intended for genomic DNA examination during the pre-examination phase before a molecular examination 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 cell free circulating DNA, which are not described in this document.
NOTE Circulating cell free DNA in blood is covered in ISO 20186-3.
Different dedicated measures are 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 document.
This document does not cover the isolation of specific blood cells and subsequent isolation of genomic DNA therefrom.
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 2: Isolierte genomische DNA (ISO 20186-2:2019)
Diese Internationale Norm gibt Empfehlungen zur Handhabung, Dokumentation, Lagerung und Verarbeitung von Proben venösen Vollbluts, die für die Untersuchung genomischer DNA vorgesehen sind, während der präanalytischen Phase vor der Durchführung einer molekularen Untersuchung. Diese Internationale Norm betrifft Proben, die mit Blutentnahmeröhrchen für venöses Vollblut entnommen wurden.
Diese Internationale Norm ist anwendbar auf alle molekularen in vitro diagnostischen Untersuchungen, die in medizinischen Laboratorien durchgeführt werden. Sie ist darüber hinaus für die Verwendung durch Kunden von Laboratorien, Entwickler und Hersteller von In vitro Diagnostika, durch Institutionen und kommerzielle Organisationen, die biomedizinische Forschungen durchführen, sowie durch Biobanken und Arzneimittelagenturen bestimmt.
Zur Stabilisierung von blutzellfreier zirkulierender DNA sind andere spezielle Maßnahmen erforderlich, die in dieser Internationalen Norm nicht beschrieben werden. Zellfrei im Blut zirkulierende DNA wird behandelt in ISO 20186 3, Molecular in vitro diagnostic examinations — Specifications for pre-examination processes for venous whole blood — Part 3: Isolated circulating cell free DNA from plasma.
Auch bei der Abnahme, Stabilisierung, dem Transport und der Lagerung von Kapillarblut sowie für die Gewinnung und Lagerung von Blut mithilfe von papierbasierten Techniken sowie anderen Techniken zur Herstellung von getrocknetem Blut sind verschiedene spezielle Maßnahmen nötig. Diese werden in dieser Internationalen Norm ebenfalls nicht beschrieben.
Diese Internationale Norm behandelt nicht die Isolierung von bestimmten Blutzellen und die anschließende Präparation von genomischer DNA aus diesen Zellen.
Auch DNA von im Blut vorliegenden Pathogenen wird in dieser Internationalen Norm nicht behandelt.
ANMERKUNG Internationale, nationale oder regionale Regelungen bzw. Anforderungen können ebenfalls für bestimmte Themen in dieser Internationalen Norm gelten.
Analyses de diagnostic moléculaire in vitro - Spécifications relatives aux processus préanalytiques pour le sang total veineux - Partie 2: ADN génomique extrait (ISO 20186-2:2019)
Le présent document fournit des lignes directrices pour la manipulation, le stockage, le traitement et la documentation des prélèvements de sang total veineux destinés à l'analyse de l'ADN génomique durant la phase préanalytique précédant la réalisation d'une analyse moléculaire. 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 à prendre pour stabiliser l'ADN libre circulant dans le sang.
NOTE L'ADN libre circulant dans le sang est traité dans l'ISO 20186‑3.
Des mesures spécifiques différentes sont prises pour prélever, stabiliser, transporter et stocker le sang capillaire, et pour prélever et stocker le sang par des technologies à base de support papier ou d'autres technologies produisant du sang séché. Ces mesures ne sont pas décrites dans le présent document.
Le présent document ne traite ni de l'extraction de cellules sanguines spécifiques ni de l'extraction de l'ADN génomique qu'elles contiennent.
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 - 2. del: Iz genoma izolirana DNK (ISO 20186-2:2019)
Ta mednarodni standard vsebuje priporočila za obravnavo, dokumentiranje, shranjevanje in obdelavo vzorcev venske polne krvi, namenjenih za analizo iz genoma izolirane DNA 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 na primer izvajajo v medicinskih laboratorijih. Uporabljali naj bi ga tudi uporabniki laboratorijev, razvijalci in proizvajalci diagnostike in vitro, nanaša pa se tudi na institucije in komercialne organizacije, ki izvajajo biomedicinske raziskave, biobanke ter regulativne organe. Krvna genomska DNA lahko po odvzemu krvi razpade ali se razkroji. Zato je treba uporabiti posebne ukrepe za pridobivanje vzorcev krvi dobre kakovosti za analizo genomske DNA. To je še posebej pomembno za analitične preskusne postopke, ki zahtevajo DNA z veliko molekularno težo. Za ohranjanje cirkulirajoče brezcelične DNA je treba uporabiti drugačne namenske ukrepe, ki niso opisani v tem mednarodnem standardu. Cirkulirajoča brezcelična DNA je opisana v standardu ISO 20091-3, Molekularne diagnostične preiskave in vitro - Specifikacije za predpreiskovalne procese za vensko polno kri - 3. del: Iz plazme izolirana cirkulirajoča brezcelična DNA Za zbiranje, stabiliziranje, prevoz in shrambo kapilarne krvi ter za zbiranje in shrambo krvi s tehnologijami, ki temeljijo na papirju, ali drugimi tehnologijami, pri katerih nastaja posušena kri, je treba uporabiti drugačne namenske ukrepe. Ti niso opisani v tem mednarodnem standardu. Patogena DNA v krvi ni zajeta 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.
