Abstract

The invention relates to a quantitative detection apparatus and method of an immunochromatographic test strip. The immunochromatographic test strip is used for detecting the concentration of a matter to be measured. The quantitative detection apparatus comprises an image shooting unit used for shooting a detection card and the immunochromatographic test strip placed on the detection card to obtain the integral image of the detection card and the immunochromatographic test strip placed on the detection card; an image processing unit used for correcting and segmenting the integral image to obtain the test image of the immunochromatographic test strip; and an analyzing and processing unit used for analyzing the test image to obtain the concentration of the matter to be measured.

Description

technical field [0001] The invention belongs to the field of mobile medical detection, and in particular relates to an immunochromatographic test strip quantitative detection device and method, where the immunochromatographic test strip is used to detect the concentration of a test substance. Background technique [0002] Colloidal gold chromatography test strips apply immune technology, chromatography technology and colloidal gold chromogenic technology, and can detect disease markers contained in blood, urine, saliva and other body fluids. Low cost and other advantages, so the development is very fast. Since the emergence of this technology, amazing development has been achieved, and dozens of measurable items have been achieved, including antigens and antibodies of infectious diseases, myocardial markers, tumor markers, hormones and various proteins. [0003] At present, colloidal gold chromatography test strips mostly use visual inspection for qualitative judgment, whic...
