What is the difference between 3 parts and 5 parts hematology analyzer?
Hematology analyzers are also known as hematology analyzers. At present, hematology analyzers on the market are mainly divided into fully automatic and semi-automatic instruments.
As this instrument has become a necessary instrument for clinical testing in hospitals and the continuous development of computer technology in recent years, the product has also shifted from three-division to five-division, and from two-dimensional space to three-dimensional space. For three-class blood cell analyzers and five-class instruments What's the difference?
1.The difference in the principle of instrument detection
Most of the three-category instruments use electrical impedance detection technology, which is composed of signal generators, amplifiers, discriminators, threshold regulators, detection counting systems and automatic compensation devices; five-category products mostly use light scattering detection technology, mainly composed of laser sources (Mostly use argon ion laser to provide monochromatic light) detection area (mainly composed of a sheath flow device to ensure that the cell suspension forms a single array of cell flow in the detection flow), detector (scattered light detection The device is a photodiode to collect the scattered light signal generated by the cell after the laser is irradiated; the fluorescence detector is a photomultiplier tube to receive the fluorescent signal generated by the cell after the laser is irradiated by the fluorescent dye).
2. The difference between white blood cell classification methods
The three-classification product divides white blood cells into lymphocytes, monocytes, and granulocytes; the five-class instrument divides white blood cells into lymphocytes, monocytes, and granulocytes (neutrophils, eosinophils, and basophils).
3. The difference between applicable customers
The three-category blood cell analyzer is mainly used in hospitals, maternal and child health care centers, clinics, and community service centers below the third grade A, and the price is relatively much cheaper; while the five-category products are mainly used in hospitals above the third grade, and the price and reagents are more expensive. a lot of. With the current needs of clinical testing, various blood cell analyzers continue to emerge. I personally think that the product is not good or bad. It is mainly to choose the right one. Customers can choose to purchase three categories according to the amount of clinical testing samples and testing standards. It is still a five-category product. In terms of clinical application, three-category instruments are more widely used. At present, Hanfang’s blood cell analyzers use three-category instruments, which are no less than five in terms of price, operation methods, and test results. Classification instrument.
