| mg/dL | <2.0 | 2.0-3.0 | >3.0 | |
| Serum albumin | g/L | >35 | 30-35 | <30 |
| g/dL | >3.5 | 3.0-3.5 | <3.0 | |
| Prothrombin time | Seconds prolonged | 0-4 | 4-6 | >6 |
| INR | <1.7 | 1.7-2.3 | >2.3 | |

Note: The Child-Pugh score is calculated by adding the scores of the five factors and can range from 5-15. Child-Pugh class is either A (a score of 5-6), B (7-9), or C (10 or above). Decompensation indicates cirrhosis with a Child-Pugh score of 7 or more (class B). This level has been the accepted criterion for listing for liver transplantation.
