A ROTEM-INTEM test is a specific analysis performed using a rotational thromboelastometry (ROTEM) device, where the "INTEM" part refers to a specific reagent that activates the intrinsic pathway of the coagulation cascade, essentially providing information similar to a standard activated partial thromboplastin time (aPTT) test, allowing for detailed evaluation of a patient's blood clotting ability by measuring clot formation time and strength through a viscoelastic analysis.
