Which of the following is NOT a criterion in Ranson's Criteria for pancreatitis?

Ranson's Criteria is a set of clinical parameters that help assess the severity and prognosis of acute pancreatitis. The criteria include various laboratory and clinical findings observed within the first 48 hours of hospital admission.

Among these criteria, elevated white blood cell count (WBC > 16,000), a significant base deficit (greater than 4 mEq/L), and a decrease in calcium levels are all included in Ranson's Criteria for pancreatitis evaluation. The presence of elevated liver enzymes is not included as part of the Ranson's Criteria. Though elevated liver enzymes can occur in cases of pancreatitis, they are not specific to this scoring system and do not directly contribute to the assessment of severity according to Ranson's Criteria.

Thus, the correct identification of elevated liver enzymes as not being a criterion underscores the need for clarity on what parameters are utilized in the assessment of acute pancreatitis severity.
