Embodiment 1

[0045] Under normal temperature and normal pressure, diluent, hemolyzing agent, sheath fluid and crude cleaning solution were prepared in a conventional way according to the components specified in the following Table 1, wherein the aromatic alcohol in the sheath fluid was benzyl alcohol; the crude product obtained from the preparation Filter with 0.2 μm fiber membrane respectively to obtain the reagent for hematology analyzer of the present invention.

Embodiment 2

[0047] The procedure of Example 1 was repeated with the components specified in Table 1 below, but substituting phenylethyl alcohol for benzyl alcohol.

Embodiment 3

[0049] The procedure of Example 1 was repeated with the components specified in Table 1 below, but diphenyl ether was used instead of benzyl alcohol.

Abstract

The invention discloses a reagent for hemocyte analyzers, which is prepared from diluent, hemolytic agent, sheath flow liquid and cleaning fluid. Compared with the prior art, the invention changes the actual state of long-term dependence on import of the reagent for hemocyte analyzers in China, and is produced and sold in China, thereby greatly reducing the production cost; the hemolytic agent in the reagent does not contain cyanogen, thereby greatly reducing the injury to health of the personnel and experiment operators in manufacturing factories, and avoiding the environment pollution of prussiates; the reagent is especially suitable for the CD3700 / 3500, CD3000 and CD3200 differential count full-automatic hemocyte analyzers of Abbott Laboratories in America, and the hemolytic agent A750test indicates the reagent achieves the ICSH standard; and the correlation coefficients of leucocyte, erythrocyte, hemoglobin, thrombocyte and the like relative to the imported ABBOTT CELL-DYN3700 / 3500 reagent are respectively greater than 0.95.

Description

technical field [0001] The invention relates to a reagent for a medical diagnostic instrument, in particular to a reagent for a blood cell analyzer. Background technique [0002] Blood cell analysis is the most commonly used item in clinical testing. It can detect pathological changes in more than 20 blood items. It is very helpful for the rational application of antibiotics, various anemia tests, blood disease screening, allergic disease screening, etc.; Analytical technology can monitor the physical condition of the human body in time, reduce the incidence of disease or control the disease. [0003] The blood cell five-category technology is the most advanced analysis technology in this field at present, and its analysis system consists of instruments and reagents. Abbott, Coulter, ABX of France, Nishimekon of Japan and other companies abroad currently produce products; among domestic manufacturers, only Shenzhen Mindray Company has reported products. For example, the CE...
