One study [17] obtained several hemostasis tests, including PT, aPTT, fibrinogen, thrombin-antithrombin complex, antithrombin III activity and fibrinolytic markers (d-dimer, plasminogen activator inhibitor, and plasminogen tissue activator), from ill preterm infants with RDS, sepsis or asphyxia and compared them to a group of healthy preterm infants. Here, PLAT is linked to Sepsis.
