The TEG 6s System: System Description and Protocol for Measurements.

A new generation of thromboelastography, TEG 6s (Haemonetics, Boston, MA), that assesses blood viscoelastic properties by resonance technology has recently been developed. This newer methodology represents a cartridge-based, automated assay aimed to improve on historical TEG performance and precision. In a previous chapter, we reviewed the advantages and limitations of TEG 6s as well as factors that affect TEG 6s and which must be considered when interpreting tracings. In the present chapter, we provide a description of the TEG 6s principle and its operation protocol.
