(a) Kaolin-activated thromboelastography (TEG) and (b) tissue factor-activated TEG tracings from an azotemic cat with bilateral perinephric pseudocysts and factor XII (FXII) deficiency; (c) kaolin-activated TEG and (d) tissue factor-activated TEG tracings from a normal cat with FXII deficiency. Part (d) is considered a normal tissue factor-activated tracing

Kaolin-activated TEG exhibited delayed clot formation characterized by markedly prolonged reaction (R) and kappa (kappa) times, and a decreased angle compared with normal (Table 1; Figures 1a and 2), whereas the TF-activated TEG revealed a normal to mildly hypercoagulable tracing characterized by a mildly increased maximum amplitude (Table 1; Figure 1b).
