Brief Summary:
The methacetin breath test (MBT) is a non-invasive liver function test which measures the ability of the liver to metabolize a tracer dose of a compound to carbon dioxide, which is exhaled. The study hypothesis is that measurement of the MBT will allow earlier detection of a decline in liver function in patients with cirrhosis who are awaiting liver transplantation.

Arm Intervention/treatment
Experimental: Laboratory assay Device: BreathID (Methacetin breath test)
13C-labeled methacetin (75 mg) is given to the patient by mouth in a small volume of water, and expired 13C-labeled carbon dioxide is measured from a nasal cannula.
