For healthcare professionals
ABIC score calculator
The ABIC score (age, serum bilirubin, INR and serum creatinine) sorts patients with alcohol-associated hepatitis into low, intermediate and high risk of death at 90 days, using cut points of 6.71 and 9. Dominguez and colleagues published it in 2008. This calculator is written for clinicians and is not a diagnosis.

Source
Dominguez M and colleagues, American Journal of Gastroenterology 2008. The formula and the cut points of 6.71 and 9 are taken from an open-access (CC BY 4.0) review, Rahimi and Pan, Biomarker Research 2015, and the units (mg/dL) from Jia and colleagues, Lipids in Health and Disease 2023, Table 1 (CC BY 4.0). The tests check the formula, both cut points and the unit conversions.
Validated in
Built from variables measured on admission in patients with alcohol-associated hepatitis and validated in an independent prospective cohort (Rahimi 2015). It is not meant for other liver diseases.
Limits
For 90-day death, sensitivity and specificity were 100% and 50% at 6.71, and 70% and 33% at 9. In a retrospective comparison of 9 scores, for 30-day mortality they were 100% and 20% at 6.71, and 60% and 80% at 9 (Rahimi 2015). The score rules out risk better than it confirms it. Unit conversions on this page are arithmetic and are not part of the published score.
Formula
ABIC = (age in years x 0.1) + (serum bilirubin in mg/dL x 0.08) + (serum creatinine in mg/dL x 0.3) + (INR x 0.8) (Rahimi 2015) (Jia 2023). The original paper is by Dominguez and colleagues (Dominguez 2008).
Worked example: age 50, bilirubin 10 mg/dL, creatinine 1.0 mg/dL and INR 2.0 give 5 + 0.8 + 0.3 + 1.6 = 7.70, the intermediate group.
To convert units on this page, bilirubin in umol/L is divided by 17.1, and creatinine in umol/L is divided by 88.4, to give mg/dL.
Risk groups
| ABIC score | Risk group | 90-day survival |
|---|---|---|
| under 6.71 | Low | 100% |
| 6.71 to 8.99 | Intermediate | 70% |
| 9 or more | High | 25% |
Source: Rahimi and Pan 2015 (Rahimi 2015). The review prints the intermediate group as 6.71 to 8.99, so a score of exactly 9 is counted as high here.
In the subgroup treated with steroids, the greatest response was in the intermediate group. The ABIC score was the only independent predictor of 1-year mortality among the models compared (hazard ratio 2.49) (Rahimi 2015). A higher cut point of 9.5 raised specificity in one study (Rahimi 2015).
