Impedance Measurement Monitors Blood Coagulation

Blood coagulation is a complex process by which clots are formed to end bleeding at an injured site. During heart-bypass surgery, blood is diverted to a heart-lung machine. An anticoagulant is administered during surgery—followed by a rapid reversal. This article describes a coagulation monitor that provides rapid, automated data—aiding patient safety, workflow, and decision making—and leading to improved outcomes.

Thank you for your article.
I also made impedance measurements on blood drops samples with the AD5933 device, but without taking care of coagulation for instance. I obtained similar results for impedance profiles along time (as in the Figure 4 in your article).
I wonder if you explained this behaviour (increase of impedance until about 20 minutes and decrease after)
Best regards
