The correlation between serum total bilirubin (TB) and direct bilirubin (DB) level with serum CEACAM1 level in HCC patients was also calculated using Spearman’s rank correlation analysis owing to the non-normal distribution of the data (mean TB ±SD = 1.64±3.45 mg/dL, median TB, IQR: 0.81, 0.58-1.48 mg/dL and (mean DB±SD : 1.06±3.03 mg/dL, median TB, IQR: 0.39, 0.26-0.72 mg/dL). Here, CEACAM1 is linked to hepatocellular carcinoma.
