The World Organisation for Animal Health (OIE) Collaborating Centre for Diagnostic Test Validation Science in the Asia-Pacific Region is a joint initiative of the CSIRO Australian Animal Health Laboratory (AAHL), the Faculty of Veterinary and Agricultural Sciences (FVAS) of the University of Melbourne and the EpiCentre, Institute of Veterinary and Biomedical Sciences, Massey University, New Zealand.

Mission statement

The Centre’s mission is to generate new knowledge and techniques that improve the use and interpretation of diagnostic tests used in human and animal health and to promote dissemination of that knowledge to the wider medical and veterinary communities.

Terms of reference

The Centre’s terms of reference are as follows:

  • To provide services to the OIE, in particular within the region, in the designated specialty, in support of the science-based development and implementation of OIE policies and, where required, seek for collaboration with OIE Reference Laboratories;
  • To propose or develop methods and procedures that facilitate harmonisation of international standards and guidelines applicable to the designated specialty;
  • To carry out and/or coordinate scientific and technical studies in collaboration with other centres, laboratories or organisations;
  • To collect, process, analyse, publish and disseminate data and information relevant to the designated specialty;
  • To provide, within the designated specialty, scientific and technical training to personnel from OIE Member Countries;
  • To organise and participate in scientific meetings and other activities on behalf of the OIE;
  • To identify and maintain existing expertise, in particular within its region;
  • To establish and maintain a network with other OIE Collaborating Centres designated for the same specialty, and should the need arise, with Collaborating Centres in other disciplines;
  • To place expert consultants at the disposal of the OIE.

Teaching

Staff across our three institutions have a broad range of experience in laboratory diagnostic methods, epidemiology and biostatistics. We combine a high level of technical expertise with wide-ranging practical experience to provide training opportunities that cover the fundamentals and theory of diagnostic test validation science as well as application of these methods in a practical setting.

Post graduate training opportunities

Please contact us if you are interested in postgraduate research opportunities in diagnostic test validation science.
