BIOMARKER DETECTING SYSTEM AND METHOD BASED ON COLLOIDAL GOLD TEST STRIP

摘要

Disclosed are a biomarker detecting system (10) and biomarker detecting method based on a colloidal gold test strip (4). The biomarker detecting method comprises the following steps: scanning, via a camera (20), a two-dimensional code (41) of a colloidal gold test strip (4) so as to obtain information about the two-dimensional code (41) of the colloidal gold test strip (4), and photographing, from a detection band (42) of the colloidal gold test strip (4), a detection result image of a biomarker; recognising the type of the biomarker according to the information about the two-dimensional code (41); locating the position, in the detection result image, of a reaction colour band of the biomarker; segmenting, according to the position of the reaction colour band, a reaction colour band region of the biomarker from the detection result image; extracting a characteristic value of the reaction colour band region, and calculating, according to the extracted characteristic value, a grey value of the reaction colour band region; and comparing the grey value of the reaction colour band region with a standard substance grey value, so as to obtain a content detection result of the biomarker. The biomarker detecting system (10) and biomarker detecting method based on a colloidal gold test strip (4) are capable of analysing the content of a biomarker on the colloidal gold test strip (4) anytime anywhere, thereby preventing a detection result deviation caused by subjectivity or an error.
