Amylase / Creatinine Clearance ratio 計算機 (FE amylase)

Acute pancreatitis と Macroamylasemia の鑑別
Amylase Clearance (%) = (Urine Amylase × Serum Cr) ÷ (Serum Amylase × Urine Cr) × 100

Serum Amylase (U/L):
Serum Creatinine (mg/dL):
Urine Amylase (U/L):
Urine Creatinine (mg/dL):

Amylase Clearance ＞ 5% : Acute pancreatitis の可能性が高い (Macroamylasemia の可能性は低い)
Amylase Clearance ＜ 1% : Macroamylasemia の可能性が高い (Acute pancreatitis の可能性は低い)
