Other: CLD (chronic liver disease)
Chronic liver disease subjects with recent biopsy will be tested with a breath tests using a 13C enriched substrate metabolized by their liver
|
Carbon 13 methacetin 75mg dissolved in 150 ml is given to the subject and metabolism is measured by a breath analyzer after decomposed by the liver

Measure Description |
Time Frame |
|---|---|---|
|
Number of Subjects With Likelihood of Cirrhosis Based on "Hepatic Impairment Score" (HIS)
Time Frame: Study day 1 after a 1 hour test
|
"Hepatic Impairment Score" (HIS) is a score based on breath test parameters and demographic parameters of the subject being tested.
A HIS value greater than 0.14 would mean that the subject is likely to be cirrhotic (based on biopsy result as the gold standard).
The HIS is a probability score,i.e.
ranges from 0 to 1, where 0 would mean the lowest probability of having liver cirrhosis and 1 would be the highest probability of having liver cirrhosis.
This would be compared to the actual biopsy result of cirrhosis detection as the gold standard.

Measure Description |
Time Frame |
|---|---|---|
|
AUC of ROC (Area Under Receiver Operating Characteristic Curve)
Time Frame: At study day 1 after 1 hour test
|
The AUC represents a summary measure of the ROC curve and is the accuracy of the HIS in detecting cirrhosis compared to the gold standard of biopsy.
