Key facts

Hepatocellular carcinoma risk [Score] by GAAD

Hepatocellular carcinoma risk

The GAAD score is used to predict the probability of developing early-stage hepatocellular carcinoma (HCC). It is calculated based on gender, age, alpha-fetoprotein (AFP), and des-gamma-carboxy prothrombin (DCP, also called PIVKA-II). In contrast, the GALAD score [LOINC96450-2] includes AFP-L3. The risk-factor score ranges from 0-10 where a higher GAAD scores correlate with increased risk of HCC.
