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

Test Catalog

Test Name

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

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

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

 

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

 

The following algorithms are available in Special Instructions:

-Laboratory Approach to the Diagnosis of Amyloidosis

-Laboratory Screening Tests for Suspected Multiple Myeloma

Specimen Type Describes the specimen type validated for testing

Urine

Shipping Instructions

Refrigerate specimen during collection and send refrigerated.

Necessary Information

24-Hour volume is required.

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Supplies: Aliquot Tube, 5 mL (T465)

Submission Container/Tube: Plastic, 60-mL urine bottle and plastic, 5-mL tube (T465)

Specimen Volume: 50 mL

Collection Instructions:

1. Collect urine for 24 hours.

2. Aliquot specimen between containers.

3. Label specimens appropriately (60-mL bottle for protein electrophoresis and 5-mL tube for protein, total).

Additional Information: See Urine Preservatives in Special Instructions for multiple collections.
