Abstract: The present invention relates to an image detection method for diagnostic plates, which detects the changes of signal lines in multiple assay regions at the same time, and promotes the detection efficiency remarkably. The diagnostic plates in the present invention may comprise Radio frequency identification (RFID) tags, and comprise at least one assay region, and at least one signal line within the assay region. This image detection method for diagnostic plates according to the present invention comprises: reading the parameters from the RFID tags of the diagnostic plates directly, or reading the alternative RFID tags provided with an RFID reader, or downloading the parameters from external files of computer; detecting the changes of the images whether reaches the stable state; analyzing and measuring the color of signal lines and the background in the image of the diagnostic plates after the images are stabilized; calculating the color intensity difference between the images of the signal line and the corresponding background; and determining the result of the signal lines in the assay region based on the difference in intensity.
