EPU - Overview: Electrophoresis, Protein, 24 Hour, Urine

Test Catalog

Test ID: EPU    
Electrophoresis, Protein, 24 Hour, Urine

Useful For Suggests clinical disorders or settings where the test may be helpful

Monitoring patients with monoclonal gammopathies


Urine protein electrophoresis alone is not considered an adequate screening for monoclonal gammopathies

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
PTUProtein, Total, UYesYes
PEUProtein Electrophoresis, UNoYes

Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Test IDReporting NameAvailable SeparatelyAlways Performed
IFXUImmunofixation, UNoNo

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If a discrete electrophoresis band is identified, the laboratory will evaluate the urine protein electrophoresis and, if necessary, perform immunofixation at an additional charge.

Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test

Method Name A short description of the method used to perform the test

PTU: Dye Binding (Pyrogallol Red)

PEU: Agarose Gel Electrophoresis

IFXU: Immunofixation

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.


Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
