The invention discloses a digital colloidal gold detection card and a digital detection method in the field of in vitro diagnosis technology. The detection line is provided with colloidal gold-labeled protein on the binding pad, the upper shell of the shell is provided with a switch button, a receiving system and a sample injection hole, the receiving system includes a photodetector and a band-pass filter lens, and the lower shell of the shell is provided with a circuit board and optical system, the optical system includes a lens, a mirror and a light source, the photodetector is connected to the mobile device through a bluetooth module, and qualitative and quantitative detection can be realized according to the transmission spectrum test method, and the photodetector on the test strip receives the transmitted light signal. , to avoid the influence of stray light on signal reception when it is located on the same side, thereby improving the detection sensitivity, the lens with band-pass filtering function reduces the influence of ambient light, and the measurement results are uploaded to the server to realize the digital and information management of colloidal gold detection. |
