Separation of serum or plasma from contact with blood cells and clots should be completed as soon as possible after the blood collection (within 2 hours): (1) Centrifugal time and relative centrifugal force (RCF): Clinical chemical analysis When the blood specimen is centrifuged, RCF (1000 to 1200) ×g, the centrifugation time is 5 to 10 min.
(2) Temperature control Centrifugation: Heat generation during centrifugation is not conducive to the stability of the analyte. Clinical chemical analysis must be performed with a temperature-controlled centrifuge when the blood specimen is centrifuged. Some temperature-dependent analytes (such as adrenocorticotropic hormone, cyclic adenosine monophosphate, catecholamines, etc.) should be separated at 4 ° C; no unusual temperature requirements of the analyte, the centrifugation temperature should be set at 20 ° C ~ 22 ° C; temperature is lower than The blood potassium measurement can be artificially increased at 15 ° C; the refrigerated specimen must be centrifuged at the required temperature. Double spiral cone mixer
(3) Storage of separated serum or plasma: laboratory temperature and storage temperature and time of serum or plasma are important parameters for analyte stability and accuracy of measurement results:
1 at 22 ° C ~ 25 ° C, serum or plasma preservation does not exceed 8h;
2 When the experiment cannot be completed within 8 hours, the serum or plasma should be stored at 2 ° C ~ 8 ° C;
The experimental items that cannot be completed within 348 hours, or the separated serum or plasma should be stored at -20 °C when stored for more than 48 hours;
4 specimens can not be frozen and thawed (can only freeze and thaw once), and can not be stored in a frost-free refrigerator (can cause sample temperature changes);
5 After centrifugation, the serum on the gel (gel barrier) can be stored for 2 to 5 days (also reported at 4 ° C for 24 hours), but the integrity of the gel must be ensured; The serum or plasma must be removed immediately afterwards.
6 Serum or plasma must be stored in a closed test tube.

Veterinary drugs refer to substances (including drug feed additives) used to prevent, treat and diagnose animal diseases or purposefully regulate animal physiological functions.
Veterinary drugs mainly include: serum products, vaccines, diagnostic products, micro ecological products, traditional Chinese medicine, Chinese patent medicine, chemicals, antibiotics, biochemical drugs, radioactive drugs, topical pesticides, disinfectants, etc.GMP in China's veterinary drug industry began to be implemented in the late 1980s. In 1989, the Ministry of agriculture of the people's Republic of China issued the code for quality management of veterinary drug production (for Trial Implementation), and in 1994, the detailed rules for the implementation of the code for quality management of veterinary drug production (for Trial Implementation). From October 1, 1995, all qualified drug manufacturers (workshops) and drug varieties can apply for GMP certification according to the requirements. The administrative department of health shall give priority to the enterprises (workshops) that have obtained the GMP certification certificate when applying for the production of new drugs. As of June 30, 1998, for enterprises (workshops) that have not obtained GMP certification, the administrative department of health will no longer accept applications for new drug production.
On March 19, 2002, the Ministry of agriculture revised and issued the new veterinary drug production quality management specification (hereinafter referred to as veterinary drug GMP specification). Announcement No. 202 was issued on June 14 of the same year, stipulating that the transition period from June 19, 2002 to December 31, 2005 is the implementation of GMP for veterinary drugs, which shall be enforced from January 1, 2006. Since then, China has poured out a large number of GMP veterinary drug enterprises
