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.

Condition Intervention Phase
Cirrhosis Device: BreathID (Methacetin breath test) Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Use of the BreathID Methacetin Breath Test to Assess Hepatic Metabolic Reserve and to Predict Hepatic Decompensation in Patients Awaiting Liver Transplantation

Enrollment: 165
Study Start Date: March 2010
Study Completion Date: July 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
