Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
An amylase, monomeric result above the upper reference limit is consistent with hyperamylasemia. An amylase, percent monomeric less than 71 percent suggests the presence of macroamylase.
Amylase, monomeric is determined after ultrafiltration. Macroamylase is removed by ultrafiltration and is not measured.
For confirmation of macroamylasemia, consider ordering Amylase, Urine (ARUP test code 0020471).
