摘要
Currently available chromogenic and fluorogenic substrates for endogenous thrombin potential (ETP) measurement are cleaved by both free (active) and alpha-2-macroglobulin-bound (inactive) thrombin, leading to an overestimation of ETP. Commercial methods for ETP measurement determine this using a mathematical algorithm, which assumes the contribution of alpha-2-macroglobulin to the ETP. This limits application of such methods to populations where variation in alpha-2-macroglobulin concentrations is observed, primarily children. This study examined the contribution of alpha-2-macroglobulin-bound thrombin to the ETP measurement in neonates, children and adults, to determine whether automated methods are appropriate for use in neonates and children.
