An Investigation of a New Activated Clotting Time “MAX-ACT” in Patients Undergoing Extracorporeal Circulation

Abstract

MAX-ACT (a new activated clotting time [ACT] test) uses more maximal clotting activation in vitro and, although it is less susceptible to increase because of hypothermia and hemodilution than ACT, lack of correlation with heparin levels remains a persistent limitation.
