REPU - Specimen: Electrophoresis, Protein, Random, Urine

Test Catalog

Test ID: REPU    
Electrophoresis, Protein, Random, Urine

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.

Specimen Type Describes the specimen type needed for testing


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.

Collection Container/Tube: Clean, plastic urine collection container

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

Specimen Volume: 50 mL

Collection Instructions:

1. Collect a random urine specimen.

2. No preservative.

3. Divide specimen between submission containers.

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

Additional Information:

1. Random urine, no volume is required.

2. If a serum specimen on the same patient will also be submitted, order PEL / Electrophoresis, Protein, Serum under a separate order number.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

25 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected










Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
