The results of TEG in ALF have been contrasting in the two studies which included predominantly paracetamol induced ALF. Stravitz et al in a study of 51 ALF patients reported normal TEG in 63%, 1 abnormality in 16%, 2 abnormalities in 10%, 3 abnormalities in 8% of patients and 4 abnormalities in 4% whereas 8% patients had TEG parameters in a hypercoagulable range though the mean of parameters were within normal limits in all patients. In another study of 20 ALF patients, TEG findings were consistent with a hypocoagulable state in 20%, normal in 45%, and hypercoagulable in 35% of the patients.
