The invention provides a near infrared fluorescence scanner. The near infrared fluorescence scanner comprises a light source, a beam splitter, a focus lens, a moving device, a timing unit, a near infrared detector as well as a controller; the controller triggers the timing unit to time so as to control the chromatography time of a test strip, and triggers the moving device to move the test strip when the timing unit exceeds time; near infrared light emitted by the light source focuses, is projected to a test strip of a sample with a near infrared fluorescence mark, and generates reflective light; the near infrared detector collects the reflective light, converts the reflective light into an electric signal, and sends the electric signal to the controller; the controller analyzes the concentration of a target object in the sample according to the electric signal, can judge whether the sample is positive or negative according to the concentration of the target object, can improve the diagnosis flexibility effectively, and also can analyze the concentration of a target detection object quantitatively.
Description
technical field [0001] The invention relates to a diagnostic instrument, in particular to a near-infrared fluorescence scanner. Background technique [0002] Immunochromatography is a rapid diagnostic technique that has emerged in recent years. Its principle is to immobilize specific antibodies on a certain area of a specific test paper. When the test paper invades the sample (urine or serum), the corresponding antigen in the sample It specifically binds to the antibody, and the colloidal gold chromogenic technology can make the test paper display a certain color. Through the color, it can be judged whether the sample is negative or positive. [0003] However, there are defects in this technology: first, the sensitivity is low, and the color cannot be developed if the sample concentration is low; second, it cannot be quantitatively analyzed. Contents of the invention [0004] Aiming at the defects of low sensitivity and inability to quantify current immunochromatography...
