Electrochemical test strip for testing multiple indicators, and testing method thereof

An electrochemical test strip for detecting renal function indicators, comprising:

• a first biosensor which comprises an insulating substrate, a first electrode system disposed on the insulating substrate, a first channel forming layer and a first upper cover layer, a first channel forming area disposed in the first channel forming layer, the first channel forming area disposed above at least one electrode of the first electrode system, wherein the electrochemical test strip further comprises a second biosensor, and the second biosensor comprises an insulating substrate, a second electrode system disposed on the insulating substrate, a second channel forming layer and a second upper cover layer, a second channel forming area disposed in the second channel forming layer, the second channel forming area disposed above at least one electrode of the second electrode system;
• a sample addition port in liquid communication with the first channel forming area of the first biosensor and the second channel forming area of the second biosensor, respectively;
• the first biosensor and the second biosensor are located on the front and back sides of the electrochemical test strip, respectively;
• wherein the first biosensor is used for determining two indicators of urea, creatinine and uric acid, and the second biosensor is used for determining a remaining third indicator of urea, creatinine and uric acid.
