Fluorescence flow cytometry can really help you<\/h2>\n

Fluorescence flow cytometry is used to analyse physiological and chemical properties of cells. It can also be used to analyse other biological particles in urinalysis analysers. It provides:<\/p>\n

Information about cell size and structure<\/strong><\/p>\n

Information about a cell\u2019s interior<\/strong><\/p>\n

 <\/p>\n

In flow cytometry, we examine cells and particles while they are flowing through a very narrow flow cell.<\/p>\n

First a blood sample is aspirated and proportioned, then diluted to a pre-set ratio and labelled with a proprietary fluorescence marker that binds specifically to nucleic acids.<\/p>\n

Next the sample is transported into the flow cell. The sample is illuminated by a semiconductor laser beam, which can separate the cells using three different signals:<\/p>\n

forward scattered light (forward scatter or FSC)<\/strong><\/p>\n

side scattered light (side scatter or SSC)<\/strong><\/p>\n

side fluorescence light (side fluorescence or SFL).<\/strong><\/p>\n

 <\/p>\n

The intensity of the forward scatter indicates the cell volume. The side scatter provides information about the cell content, such as nucleus and granules. The side fluorescence indicates the amount of DNA and RNA present in the cell.<\/p>\n

Cells with similar physical and chemical properties form a cluster in a graph known as a scattergram.<\/p>\n

The principle of fluorescence flow cytometry is used in different analysers for haematology and urinalysis. For blood cell counts we use fluorescence flow cytometry, e.g. for the WBC and differential, for NRBC counting and reticulocyte measurement.<\/p>\n

In urinalysis analysers, fluorescence technology is also used for counting bacteria, red blood cells, white blood cells and other elements.<\/p>\n

Red blood cells, platelets, haemoglobin and haematocrit<\/h2>\n

The XS-500i<\/em> may be compact, but it uses the same globally-renown detection technologies as Sysmex\u2019s larger analysers. And thanks to its absolute counting principle, you don\u2019t need to calibrate the particle counts yourself, which will save you a significant amount of time and effort.<\/p>\n

Red blood cells and platelets<\/strong><\/h4>\n

For red blood cells and platelets, the XS-500i <\/em>uses advanced sheath flow impedance technology. This hydrodynamic focusing is more precise than ordinary methods as it eliminates potential errors such as coincidence and recirculation. In practical terms, this lets you spot changes in red blood cell composition in the peripheral blood. This is the essential basis for screening and classifying anaemic forms of disease. And it works even for samples with extremely low or unusually high numbers of red cells and platelets.<\/p>\n

Haemoglobin<\/strong><\/h4>\n

The XS-series uses Sysmex\u2019s cyanide-free SLS method for analysing haemoglobin. This correlates excellently with the reference method. Since haemoglobin is determined in a dedicated channel, interference with lipids or high concentrations of WBC is minimised.<\/p>\n

Haematocrit <\/strong><\/h4>\n

The XS-500i<\/em> measures haematocrit using a precise red blood cell count and volume detection. Using what is known as the \u2018cumulative pulse height\u2019 detection method, the pulses and the resulting cell volumes of a defined sample volume are added together to give a direct, extremely accurate haematocrit value.<\/p>\n<\/div>\n<\/div>\n
