Abstract
The use of thyroid function tests as a method of monitoring patients with fulminant hepatic failure has been previously proposed. The use of these indices in two cases with fulminant hepatic failure are described. Both patients had simultaneous ingestion of hepatotoxic mushroom (amanita virosa). Their parallel clinical courses and recovery without liver transplantation is described, outlining the potential long term cost-savings achievable by such tests in the selection of patients for liver transplantation and the need for further study of these indices for this application.
