Aspects of kit validation for tests used for the diagnosis and surveillance of livestock diseases: producer and end-user responsibilities
|Author(s) :||J.R. Crowther, H. Unger & G.J. Viljoen|
The Joint Food and Agriculture Organization/International Atomic Energy Agency (IAEA) Division of Nuclear Techniques in Food and Agriculture, based at the IAEA in Vienna, Austria, has extensive experience in helping to develop and validate assays and has provided strong support in developing World Organisation for Animal Health (OIE) norms. This paper will focus on enzyme-linked immunosorbent assay and polymerase chain reaction as the major technologies exploited in diagnosis and surveillance. Problems involving the terminology and factors in kit production, supply and validation are examined, in particular emphasising the importance of robustness and ruggedness of tests. The authors discuss the responsibilities of the various stakeholders (producers, distributors, users, and national/international organisations) in achieving quality controlled data to solve diagnostic and surveillance problems. The roles of internal quality control (internal proficiency testing) and external quality assurance (external proficiency testing) as well as aids to solving problems with kits are examined.
