The invention relates to a correction test strip for an immunochromatographic test strip quantitative detecting instrument, and a manufacturing method of the correction test strip. The correction test strip can be used for correcting the immunochromatographic test strip quantitative detecting instrument taking nanogold particles, high-molecular nanometer fluorescent particles and other long-decayed materials as developing markers; a developing window of the correction test strip comprises a developing testing line, a quality control line and a cellulose nitrate membrane blank area; the color of the testing line darkens and comprises at least five grades; the colors of the testing line and the quality control line are converted into digital images by a scanner, a digital camera or other image acquisition device through real test strips with corresponding colors and can be obtained thorugh processing of image processing software on a computer; the color of each grade can be determined by collecting not less than 20 real test strip images of the same color range; the testing line and the quality conrol line are printed on a cellulose nitrate membrane by a color printer according to the size of a real immunochromatographic test strip and the color of a corresponding image; and the cellulose nitrate membrane used for printing is fixed on a plastic base plate.
Description
technical field [0001] The invention relates to a calibration test strip of an immunochromatography test strip quantitative detector and a manufacturing method thereof, belonging to the technical fields of instrument science, biomedical engineering, etc., and in particular to the quantitative detection technology of the immunochromatography test strip. Background technique [0002] Existing patents for immunochromatographic quantitative detectors are mainly based on the principle of quantitative detection, most of which are based on the principle of light reflection, using a light source with a certain wavelength and intensity to irradiate the test window of the immunochromatographic test strip, using optical fiber as the optical signal transmission medium, Through photoelectric sensing devices (such as photodiodes, phototransistors, CCD, CIS, CMOS, etc.), the reflected light signals in the three areas of the test line, quality control line and blank area in the test strip te...
