Adaptive medical POCT system and detection method

The invention discloses an adaptive medical POCT system and a detection method, includes a scanning device for scanning an image of a test paper card, processing means for receiving the image, and display means for displaying a detection result, the processing means being programmed to perform the following steps: identifying a detection item and a characteristic value corresponding to the test paper card from the image, and comparing the detection item of the test paper card with an item in a database; if there is no test item in the database, the fitting formula of the test item is obtainedby test paper card training and stored in the database; and the detection item already exists in the database, the fitting formula corresponding to the detection item is called from the database, andthe eigenvalue of the image is substituted into the fitting formula to calculate the detection result. The invention does not need to upgrade the system software after the new detection item is generated, and the new detection
