Regarding Ranson's criteria, calcium less than 8 is part of the admission criteria.

Ranson's criteria assess pancreatitis severity using two time points: on admission and at 48 hours. Calcium below 8 mg/dL is not part of the admission criteria; it appears in the 48-hour criteria as a marker of more severe disease. On admission, the criteria are age >55, white blood cell count >16,000/mm3, blood glucose >200 mg/dL, AST >250 U/L, and LDH >350 U/L. The 48-hour criteria include hematocrit drop >10%, BUN increase, calcium <8 mg/dL, arterial PO2 <60 mmHg, base deficit >4 mEq/L, and fluid sequestration >6 L. A low calcium level at 48 hours indicates more severe pancreatitis and worse prognosis. Therefore, the statement is false.
