Objective To investigate the predictive value of serum calcium ion (Ca2+), random blood glucose (RBG), C-reactive protein to albumin ratio (CRP/ALB) for the severity of early acute pancreatitis (AP). Methods The clinical data of 138 patients with AP who were hospitalized at the Seventh Affiliated Hospital of Sun Yat-sen University from July 2020 to August 2025 were retrospectively analyzed. Among them, 99 cases were in the mild acute pancreatitis (MAP) group, and 39 cases were in the non-mild acute pancreatitis (including moderate and severe, NMAP) group. Univariate analysis was conducted on the age, RBG, amylase (AMY), lipase (LPS), white blood cell (WBC), neutrophil (N), lymphocyte (L), hemoglobin (Hb), hematocrit (HCT), sodium(Na+), potassium(K+),Ca2+, serum creatinine (Cr), blood urea nitrogen (BUN), fibrinogen (Fib), D-dimer (D-dimer), carbon dioxide combining power (CO₂CP), procalcitonin (PCT), C-reactive protein (CRP), albumin (ALB), procalcitonin to albumin ratio(PCT/ALB), and CRP/ALB of the two groups. The indicators related to the severity of AP were selected through ROC curve analysis and binary logistic regression analysis. Results The areas under the ROC curve for Ca2+, RBG, and CRP/ALB in predicting the severity of AP were 0.750, 0.697, and 0.864, respectively. Logistic regression analysis showed that Ca2+ [OR = 0.014, 95% CI (0.001, 0.313)], RBG [OR = 1.159, 95% CI (1.024, 1.311)], and CRP/ALB [OR = 1.393, 95% CI (1.186, 1.637)] were independent risk factors for early prediction of AP severity. Conclusion The lower the Ca2+, the higher the RBG, and the higher the CRP/ALB ratio, the greater the possibility of AP patients developing into severe cases. The RBG and CRP/ALB ratio are positively correlated with the severity of the disease in AP patients, while Ca2+ is negatively correlated with the severity of the disease in AP patients.
