Aiding in the evaluation of acute pancreatitis

 

This test is not useful for diagnosing or characterizing pancreatic cancer or cysts.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Amylases degrade complex carbohydrates (starches) into simple sugars. Two isoenzymes, pancreatic and salivary, are found in serum. Serum pancreatic amylase should always be interpreted in a context of total amylase to determine the relative contribution of salivary and pancreatic isoenzymes.

 

Imaging tests have become the diagnostic tests of choice for diagnosing pancreatitis. Pancreatic isoamylase may be used as an adjunct to totally serum amylase, serum lipase, and imaging tests.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

0-<24 months: 0-20 U/L

2-<18 years: 9-35 U/L

> or =18 years: 13-53 U/L

Interpretation
Provides information to assist in interpretation of the test results

Increased concentrations of pancreatic amylase isoenzymes in a context of elevated total serum amylase may indicate pancreatitis.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Elevations of pancreatic amylase may be seen in patients that have macroamylase present. This elevation is caused by the inability of macroamylase to be excreted in the urine and is not diagnostic for pancreatitis, pancreatic cancer or cysts. The presence or absence of macroamylase may be determined by utilizing serum lipase and urinary amylase tests.

 

Detection of chronic pancreatitis can only be aided by pancreatic amylase during acute episodes.

Icodextrin-based medications may lead to decreased amylase values.

 

In very rare cases of gammopathy, in particular type IgM (Waldenstrom macroglobulinemia), may cause unreliable results.

Method Description
Describes how the test is performed and provides a method-specific reference

After immunoinhibition with antibodies against human salivary alpha-amylase the amount of pancreatic alpha-amylase in a sample is selectively determined by an enzymatic colorimetric method using the substrate 4,6-ethylidene-p-nitrophenyl-alpha-D-maltoheptaoside (ethylidene-G7PNP).(Package insert: Alpha-Amylase EPS Pancreatic, Roche Diagnostics; V 13.0. 01/2020)

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Monday through Saturday

Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

1 to 3 days

Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

7 days

Performing Laboratory Location
Indicates the location of the laboratory that performs the test

Test Classification
Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.

This test has been cleared, approved, or is exempt by the US Food and Drug Administration and is used per manufacturer's instructions. Performance characteristics were verified by Mayo Clinic in a manner consistent with CLIA requirements.

CPT Code Information
Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.

CPT codes are provided by the performing laboratory.
