Dominance: the current situation, in the majority of grass-roots clinics in the three-classification of the instrument is still dominant. The measurement principle of the three-classification blood cell analyzer is to use the resistance resistance method, and its measurement principle is still mainly based on the characteristic that blood cells are bad conductors of electricity. Most of the five classifications use light scattering detection technology, which is mainly composed of a laser source, a detection zone, and a detector.
2, the difference between the leukocyte classification methods:
Three classifications and five classifications are actually for white blood cells. Three classification refers to the leukocytes into three major categories, is through a certain dilution will be respectively small cell group (lymphocytes), intermediate cell group (eosinophils, basophils and monocytes) and large cell group (neutrophils). The five classifications refer to the direct division of leukocytes into neutrophils, lymphocytes, eosinophils, basophils, and monocytes with the help of certain dilutions and chemical staining methods.
3, the price difference:
Three classified and five classified analyzers are different prices, three classified instruments are cheaper, more suitable for use in the grass-roots clinics, which can meet the testing needs, but also do not need to invest in excessive costs, can be a short-term return to profit.
4, the difference between the applicable units:
Three classified analyzers are mainly applicable to the three A hospitals, maternity and child health care hospitals, clinics, and community service centers, etc., the price is relatively cheaper; five classified is mainly used for more than three hospitals, the price and reagents to be much more expensive.
