The invention discloses an 
electrochemical detection method for activating 
blood coagulation time, which comprises the following specific steps: S1, fixing a detection 
reagent on an 
electrode substrate, pasting a membrane, 
cutting the 
electrode substrate into strips, and packaging a 
test card finished product; s2, during detection, inserting the 
test card into a coagulation analyzer, and adding ablood sample to be detected; s3, after the 
blood coagulation analyzer detects that the to-be-detected blood sample enters the reaction cavity of the 
test card, applying alternating 
voltage, starting aheating piece of the detection module for heating, wherein the temperature is controlled to be 37 DEG C + / -0.5 DEG C; s4, in the detection process, along with solidification of the blood sample, enabling a current 
signal in a reaction cavity of the test card to change, enabling a detection module of the coagulation analyzer to receive the current 
signal, converting the current 
signal into a 
voltage signal through an 
operational amplifier chip, carrying out 
data acquisition and 
processing, and finally, adopting a mathematical 
algorithm to obtain an inflection point of a coagulation 
reaction curve; and calibrating the inflection point to obtain a detection result. The 
electrochemical detection method of the activated 
blood coagulation time is simple and controllable to operate and can improve the detection accuracy and stability.
