Standard Volume: 1 mL serum
Minimum Volume: 0.5 mL serum
Transport: Frozen on dry ice.
Comments: Useful for diagnosing acute pancreatitis. Detection of chronic pancreatitis can only be aided by p-amylase

during acute episodes. Not useful for diagnosing pancreatic cancer.

Rejection Criteria: Specimen other than serum; gross hemolysis, gross lipemia, or gross icteric.

Reference Range:
0- <24 months 0-20 U/L
2 – <18 years 9-35 U/L
≥ 18 years 11-54 U/L
Pancreatic amylase is elevated in acute pancreatitis within 12 hours of onset and persists 3 to 4 days. The elevation is usually 4-fold to 6-fold the upper reference limit. Macroamylase may cause less dramatic and more persistent elevations of p-amylase over weeks or months. This is usually accompanied by a reduced amylase clearance.
