Electrophoresis, Protein, Random, 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:
Specimen Type Describes the specimen type validated for testing
Advisory Information
Random urine specimens may be sufficient for identifying monoclonal proteins, but 24-hour specimens should be used to quantitate and monitor urinary abnormalities. See MPSU / Monoclonal Protein Study, 24 Hour, Urine.
Shipping Instructions
Refrigerate specimen after collection and send refrigerated.
Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Supplies:
Urine Container, 60 mL (T313)
Aliquot Tube, 5 mL (T465)
Submission Container/Tube: Plastic, 60-mL urine bottle and plastic, 5-mL tube
Specimen Volume: 50 mL
Collection Instructions:
1. Collect random urine specimen.
2. Aliquot at least 25-mL specimen in plastic, 60-mL urine bottle and at least 1-mL of specimen in plastic, 5-mL tube.
3. Label specimens appropriately (60-mL bottle for protein electrophoresis and 5-mL tube for protein, total).
Special Instructions Library of PDFs including pertinent information and forms related to the test
Specimen Minimum Volume Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| All specimens will be evaluated at Mayo Clinic Laboratories for test suitability. |
