Abstract: | Vaccination is the key strategy to prevent and control classical swine fever in China. Detection of vaccine-induced antibody by ELISA is the main method to assess the efficacy of vaccination. In order to evaluate the ability of individual laboratories for antibody detection against classical swine fever virus, Certification and Accreditation of the People's Republic of China organized the national proficiency testing program “Diagnostic Techniques for Classical Swine Fever” (CNCA-19-A01). The National/OIE Reference Laboratory for Classical Swine Fever (NRLCSF) that affiliated to China Institute of Veterinary Drug Control is responsible for the implementation of the program. Positive and negative samples were prepared and numbered randomly. Each participant received 4 different samples, and then the samples were tested according to their selected ELISA methods. All participants should submit their test results and the original reports to NRLCSF. If the results is unsatisfied, the participant will have another chance to retest. If the result is still unsatisfied, the participant will be considered unqualified for CSFV antibody detection. One hundred and three institutions participated this program. The accurate rate is 92.23% (95/103) for the first round of test, and 100% for the first and second tests. This result demonstrated that all participate laboratories provide competence for the detection of CSFV antibody and they could meet the requirement for CSFV diagnosis and surveillance. This proficiency testing program could help participants to investigate the reason for disagreement and implement their deficiencies. |
