TEG Analyzer Parameters
The TEG analyzer uses various parameters to determine a clot’s properties.
These parameters determine clot formation, lysis, kinetics, strength and
stability.
The following table lists each parameter and its definition.
Parameter Description
R Reaction time. The amount of time between the start of
the test and the beginning of coagulation.
K The speed of formation of the clot from R time to a
specific clot strength.
Alpha (Angle) The speed of clot strengthening.
MA Maximum Amplitude. The ultimate strength of the clot.
LY30 Percent lysis 30 minutes after MA is finalized. The LY30
measurement is based on the reduction of the tracing
area that occurs between the time that MA is measured
until 30 minutes after the MA is finalized.
TEG-ACT
Calculates an ACT (Activated Clotting Time) value from
the R parameter for RapidTEG™ tests.
FLEV Calculates a FLEV (Functional Fibrinogen Level) value
from the MA parameter for Functional Fibrinogen tests.
% Inhibition Indicates the reduction in platelet contribution to overall
clot strength. Displayed for PlateletMapping tests.
% Aggregation Indicates the percent of platelets not inhibited,
determined by comparing the uninhibited platelet
contribution to the baseline platelet contribution.
Displayed for PlateletMapping tests.
