Abstract
The present invention provides an electrochemical test strip (200) for detecting multiple indicators and a test method thereof. The electrochemical test strip includes a first biosensor (100) provided with an insulating substrate (1), a first electrode system, a first channel forming layer (4) and a first upper cover layer (5), and a second biosensor (101) provided with an insulating substrate (8), a second electrode system, a second channel forming layer (11) and a second upper cover layer (12). The first biosensor (100) and the second biosensor (101) are located on the front and back sides of the electrochemical test strip (200), respectively. A sample addition port (6) of the electrochemical test strip (200) is in liquid communication with a first channel forming area (55) of the first biosensor (100) and a second channel forming area (56) of the second biosensor (101), respectively.
