This standard is a revision of GB/T14926-21-1994k "Detection method for immune-hemorrhagic disease virus in laboratory animals". In addition to the relevant contents of "5.1 Detection of immunoglobulin virus antigen\ and \5.2-2 ELISA detection of immunoglobulin virus antibody\, the result judgment standard in \5 Detection method and result judgment\ has been revised.
This standard was proposed and coordinated by the Ministry of Science and Technology of the People's Republic of China, and the drafting of this standard was signed by the Chinese Society of Laboratory Animal Science. The main drafter of this standard is He Zhengming
This standard was first issued in January 1994.

Detection method
GB/T14926-21-2001
The HA method (see GB14926.53-2001) was used for virus antigen detection. The HAI method (see GB/T14926-54-2001) was used for blood testing. 5-2
6 Results judgment
6-1 For common delayed immunizations such as lumbar vaccination, the HAI antibody titer should be >1:106-2 For clean delayed immunizations, the first vaccination should not be carried out. The HAI antibody titer ≤1+10 is judged as positive. For positive (HAI antibody titer>1:10) test results, the same method is used for retesting. If it is positive, it is judged as positive. 6- The supernatant of the liver is changed to 10 before the new house. The HA concentration is 1+16 for positive. For positive (HA concentration -16 test results, the same method is used for retesting. If it is still positive, it is judged as positive. Result report
