Predicting Lung Injury From Transfusion in Patients With Liver Disease
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
A certain molecule floating in the blood may represent a risk of lung injury after a transfusion. We are determining whether detection of this molecule on a simple blood clotting test will predict the development of lung injury due to transfusion in bleeding patients with chronic liver disease.
