thromboelastography
Pronunciation: throm-bo-ee-las-TOG-ra-fee
Point-of-care test measuring blood clot formation and breakdown in real-time.
Full Definition
Thromboelastography is a viscoelastic hemostatic assay that provides real-time information about the entire coagulation process from initial clot formation through fibrinolysis. Unlike traditional coagulation studies, TEG provides functional assessment of platelet function, fibrinogen levels, and clot stability. This test is particularly valuable in surgical patients requiring massive transfusion, guiding targeted blood product therapy.
Usage
Usage note: Often abbreviated as TEG; similar to but distinct from ROTEM technology.
In Context
- "Thromboelastography guided our coagulation management during liver transplantation." — operative report
