Term Description

This test calculates the ratio of pancreatic amylase (P-amylase) to creatinine that is filtered by the kidneys. It is used to evaluate conditions such as pancreatic disease, proteinuria and macroamylasemia.
Human amylase (1,4-alpha-D-glucanglucanohydrolase) consists of two major isomers, pancreatic amylase (P-amylase) and salivary amylase (S-amylase). The isomers are identical is size but have a different charge where S-amylase is more anionic than P-amylase. JM Wetzels, et al (1988) demonstrated that the mean fractional excretions of these isomers were negatively correlated due to the differences in charges. [PMID 2450698]

Part Descriptions

LP15360-8   Amylase.pancreatic
The pancreas makes amylase (alpha amylase) to hydrolyze dietary starch into carbohydrates which are converted to glucose to provide the body with energy. Elevated pancreatic amylase levels can be found in pancreatic pleural effusions from patients with pancreatitis. Source: Regenstrief LOINC

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
