Immunofluorescence technology (Immunofluorescence technique), also known as fluorescent antibody technology, is one of the earliest development of labeling immune technology. It is a technology based on immunology, biochemistry and microscopy. For a long time, some scholars have tried to combine antibody molecules with some tracer substances and use antigen-antibody reaction to locate antigen substances in tissues or cells.
Immunofluorescence analyzer is suitable for in vitro quantitative detection of human serum, plasma, whole blood C- reactive protein, human chorionic sac gonadotropin, pregnancy alpha-fetoprotein, thyroid stimulating hormone content, test results for clinical diagnosis.
The fluorescence immunoassay analyzer consists of an optical unit, a mechanical unit, a control unit, an output display unit and a component card of a detection system. When the sample detection card is inserted into the fluorescence immunoassay quantitative analyzer, the internal two-dimensional code scanner reads the detection card information, the processor controls the mechanical transmission device to transmit the detection card to the laser detection area, the LED excitation light source irradiates the detection card according to the two-dimensional code information, and then the optical signal is collected and converted into an electrical signal; The control unit collects the signal, automatically calculates the content of the analyte in the test sample according to the software, and outputs to the display screen. The analyzer comes with a thermal printer, which can print the test results directly.
