Fluorescent immunoassay is a method that combines the specificity of an immunological reaction with the sensitivity of a fluorescent technique. The fluorescent immunoassay analyzer is based on the principle of immunochromatography, a light source with specific wavelength irradiates a test area of a detection card, a fluorescent marker positioned in the test area emits light with different wavelength from light of the light source after being excited and is captured by a photoelectric sensing device to form a current signal, and the magnitude of the current is related to the concentration of an analyte in a sample, so that qualitative or quantitative analysis of the analyte in the sample is realized. The fluorescent immunoassay instrument can be used for common fluorescent detection and time-resolved fluorescence measurement.
