Discussion on the Scope Expression of CNAS Laboratory Accreditation in Veterinary Pathology Testing Field

At present, due to some differences in the scope expression of veterinary pathology testing accreditation ability, the laboratory accreditation of China National Accreditation Service for Conformity Assessment (CNAS) is not standardized and uniform in the process of application of expanded items in the field of veterinary pathology testing and the process of assessors' evaluation, which makes many laboratories engaged in laboratory animal pathology testing and scientific research fail to obtain relevant qualifications.This article discussed the problems of scope expression in the field of CNAS veterinary pathology accreditation, and compared the expression with other veterinary pathology laboratories in other countries including the United Kingdom, the United States, Canada, New Zealand, and Singapore. The scope expression in medical pathology laboratories accredited by CNAS and some other ISO/IEC 17025 accreditation organizations were also compared. Combined with the accreditation practice of veterinary pathology laboratories in China, this paper put forward some suggestions on the scope expression in veterinary pathology testing field, so as to further unify and standardize the scope expression in veterinary pathology testing field in China, and improve the standardization of accreditation system in China
