AB Viscoelastic  testing  allows  for  the  rapid  assessment  of  the  hemostatic  properties  of  whole  blood,  measuring  clot  formation,  strength,  and  breakdown.1  The  most  common  forms  of  viscoelastic  testing  commercially  available  include  rotational  thromboelastometry  (ROTEM)  and  thromboelastography  (TEG).  These  tests  both  evaluate  hemostasis  in  a  similar  fashion  and  with  a  similar  graphical  result,  although  they  contain  slightly  different  proprietary  terminology.  TEG  has  traditionally  been  performed  by  combining  whole  blood  with  reagents  in  an  oscillating  cup  with  a  suspended  pin  and  associated  torsion  wire.  The  new  TEG  6s  is  a  cartridge-based  system  with  four  channels,  piezoelectric  actuator,  and  paired  optical  detection  system.2  This  cartridge-based  system  improves  ease  of  use  and  intradevice  reliability.3,4  Studies  have  shown  that  TEG/ROTEM  can  detect  hypercoagulability  of  pregnancy,  effects  of  heparin,  patients  at  risk  of  thrombosis,  and  guide  transfusion  in  postpartum  hemorrhage.5
