Abstract:
1. A diagnostic test device, comprising: a test strip plate or cassette configured for detecting pathological change, the test strip plate or cassette comprising a test strip and being configured for generating a control line and two test lines at respective specific positions of the test strip according to a test result; and a test strip reader comprising: four light sources; a timing generator configured for generating time-controlled signals; a driver configured for driving the light sources to emit lights to sections of the test strip corresponding to the control line and the test lines and to a background of the test strip, respectively, in sequence according to the time-controlled signals; four photo detectors configured for receiving the lights reflected from the sections of the test strip and from the background of the zone, respectively, in sequence according to the time-controlled signals and generating a detecting signal; a signal processor configured for processing the detecting signal to generate a result signal corresponding to the test result; and a display configured for display the test result according to the result signal; wherein the timing generator, the driver, and the signal processor are integrated into a printed circuit board (PCB), and the light sources, the photo detectors, and the display are mounted on and electrically connected to the PCB at appropriate positions.
