Animal health diagnostic analyses - Control of in-vitro diagnostic reagents - Part 2: Reagents for immunological techniques
The level of requirements presented in the EN 18000 series has been established as a priority for infectious diseases (bacterial, viral, fungal or parasitic) and associated animal species for which harmonization of practices in this area is needed, i.e. those for which the national, regional or international regulatory framework provides for the control of trade in animals and/or animal products and/or the definition of a health status (absence of infection) of areas, establishments or individuals.
The EN 18000 series is therefore not intended to be applicable to all existing diagnostic reagents, in particular those for which certain parameters described in this standard cannot be validly evaluated in accordance with international requirements, due e.g. to the absence of a specific reference standard and/or accessible and duly validated reference materials.
This second part describes the control, in the above-described framework, of in vitro reagents for immunological analyses with a qualitative expression of results used in animal health. It involves control organizations (CO) and applicants (including their subcontractors, when relevant).
Tiergesundheitsdiagnostische Analysen - Kontrolle von in-vitro-diagnostischen Reagenzien - Teil 2: Reagenzien für immunologische Verfahren
Das in der Reihe EN 18000 dargelegte Anforderungsniveau wurde mit Priorität auf Infektionskrankheiten (Bakterien, Viren, Pilze oder Parasiten) und die entsprechenden Tierarten festgesetzt, für die eine Harmonisierung der Praktiken in diesem Bereich erforderlich ist, d. h. für diejenigen, für die der nationale, regionale oder internationale Regelungsrahmen die Kontrolle des Handels mit Tieren und/oder tierischen Erzeugnissen und/oder die Festlegung eines Gesundheitsstatus (Infektionsfreiheit) von Gebieten, Einrichtungen oder Personen vorsieht.
Die Reihe EN 18000 ist daher nicht für die Anwendung auf alle vorhandenen diagnostischen Reagenzien vorgesehen, insbesondere nicht auf solche, für die bestimmte in dieser Norm beschriebene Parameter nicht in Übereinstimmung mit internationalen Anforderungen gültig bewertet werden können, z. B. weil kein spezifisches Referenzverfahren und/oder keine zugänglichen und ordnungsgemäß validierten Referenz¬materialien zur Verfügung stehen.
In diesem zweiten Teil wird die Kontrolle von In vitro-Reagenzien für immunologische Analysen mit qualitativer Angabe der Ergebnisse im Bereich der Tiergesundheit in dem oben dargestellten Rahmen beschrieben. Er betrifft Kontrollorganisationen (CO) und Antragsteller (gegebenenfalls einschließlich Untervertragnehmer).
Analyses de diagnostic en santé animale - Contrôle des réactifs de diagnostic in vitro - Partie 2 : Réactifs pour les techniques immunologiques
Le niveau d’exigences présenté dans la série EN 18000 a été établi en priorité pour les maladies infectieuses (bactériennes, virales, fongiques ou parasitaires) et les espèces animales associées pour lesquelles une harmonisation des pratiques dans ce domaine est nécessaire, c’est-à-dire celles pour lesquelles le cadre réglementaire national, régional ou international prévoit le contrôle des échanges d’animaux et/ou de produits animaux et/ou la définition d’un état sanitaire (absence d’infection) des zones, établissements ou individus.
La série EN 18000 n’est donc pas destinée à être applicable à tous les réactifs de diagnostic existants, en particulier ceux pour lesquels certains paramètres décrits dans la présente norme ne peuvent pas être évalués de manière valable conformément aux exigences internationales en raison, par exemple, de l’absence d’une norme de référence spécifique et/ou de matériaux de référence accessibles et dûment validés.
Cette seconde partie décrit le contrôle, dans le cadre décrit ci-dessus, des réactifs in vitro pour les analyses immunologiques avec une expression qualitative des résultats utilisés en santé animale. Elle implique les organismes de contrôle (OC) et les demandeurs (y compris leurs sous-traitants, le cas échéant).

European foreword
This document (prEN 18000-2:2023) has been prepared by Technical Committee CEN/TC 469 “Animal
health diagnostic analyses”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.

Introduction
The objective of the EN 18000 series is to facilitate the mutual recognition of the work of the animal health
in vitro diagnostic reagent control organizations at European level (or even more widely) and thus to
eventually allow the use of strategic reagents controlled by a single control organization for a given disease.
The EN 18000 series aims to describe the optimal requirements for in vitro diagnostic reagents in animal
health. It is divided into three parts. The first part concerns terms and definitions and the submission of a
reagent dossier to a control organization for control and approval. The second and third parts concern the
specific aspects of the control of an immunological diagnostic reagent and of a polymerase-chain reaction
diagnostic reagent for the detection or quantification of pathogen-specific nucleic acids (PCR), respectively.
Like any standard, it is intended to be voluntary and, if its use is prescribed by a competent authority or any
other animal health stakeholder, it will be up to them to determine for which diseases this standard be
applied by the control bodies they have designated for this purpose.

1 Scope
The level of requirements presented in the EN 18000 series has been established as a priority for infectious
diseases (bacterial, viral, fungal or parasitic) and associated animal species for which harmonization of
practices in this area is needed, i.e. those for which the national, regional or international regulatory
framework provides for the control of trade in animals and/or animal products and/or the definition of a
health status (absence of infection) of areas, establishments or individuals.
The EN 18000 series is therefore not intended to be applicable to all existing diagnostic reagents, in
particular those for which certain parameters described in this standard cannot be validly evaluated in
accordance with international requirements, due e.g. to the absence of a specific reference standard and/or
accessible and duly validated reference materials.
This second part describes the control, in the above-described framework, of in vitro reagents for
immunological analyses with a qualitative expression of results used in animal health. It involves control
organizations (CO) and applicants (including their subcontractors, when relevant).

4 General control steps
The reagents are controlled according to this standard when the regulations or authorities so require.
Depending on the context (e.g. regulation, disease control programme) of the implementation of analyses
with such reagents, the control may include an initial conformity control and several batch-to-batch controls.
Certain steps of the reagent control may be subcontracted by the CO, provided that it ensures that the
subcontractors possess the necessary skills (e.g. accreditation) and are independent.
Here are described the optimal requirements for each of the steps of the control, without defining the criteria
of conformity, which shall be specified beforehand by the CO according to the state of art (e.g. existing disease
test-specific standards, consensus conference recommendations, scientific literature). If necessary, or based
on a particular risk or epidemiological context, additional control tests may be performed that are not
described in detail in this standard.
5 Prerequisites of the reagent control for the control organization
5.1 General
The prerequisites of the control of reagents include:
— the availability of reference materials (RMs);
— the definition of the minimum performance requirements of the reagents (e.g. regulations, standards,
guidelines);
— additional useful information (e.g. templates) provided by the CO, when relevant to harmonize as far as
possible the implementation of control between the CO and the applicant.
5.2 Reference materials
The CO shall possess characterized positive RMs and negative RMs. The RMs may exist in the form of different
matrices in different levels of concentration.
The CO shall provide the applicant with RMs, so that the applicant can prepare its internal RMs in order to
conduct the control described in this standard (refer to ISO Guide 30; ISO/DIS 33403;). With these RMs, it
may provide the characteristics listed in Annex A of prEN 18000-1:2023. For certified RMs, the
characteristics appearing on the certificate to be provided are listed in ISO/DIS 33401.
The RMs may also be prepared and/or supplied by third parties, provided that they meet the criteria defined
by the CO and have been approved by the latter.
Certain RMs are defined by regulations or standards.
For certain matrices (e.g. wet blots), the RMs shall be produced under conditions as close to reality as
possible. If possible, the CO shall provide the user and the applicant with the production protocol.
The CO is not required to provide the field samples or the samples produced by experimental infection that
are necessary for the assessment of the diagnostic sensitivity and specificity.
5.3 Definition of the objectives of the reagents
The CO shall specify in writing the objectives of the reagents for the applicant (regulatory an
