TEG
Pronunciation: teg
Also written as: TEG — Thromboelastography
Point-of-care test that measures the viscoelastic properties of blood clotting to guide hemostasis management.
Full Definition
Thromboelastography (TEG) is a specialized coagulation test that provides real-time assessment of clot formation, strength, and breakdown. In surgical critical care, TEG is invaluable for managing coagulopathy in bleeding patients, guiding blood product transfusion decisions, and monitoring anticoagulation reversal. The test produces a characteristic tracing that displays multiple parameters including R-time (time to clot initiation), K-time (clot formation speed), angle (rate of clot strengthening), and MA (maximum amplitude representing clot strength). TEG allows for more precise and rapid coagulation management compared to traditional laboratory tests.
Usage
Usage note: Pronounced 'teg' as a word, not spelled out as T-E-G.
