Monoclonal Protein Study, 24 Hour, Urine

Specimen Type Describes the specimen type needed for testing

Urine

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.

Container/Tube: Plastic, 60-mL urine bottle and plastic, 6-mL tube (Supply T465)

Specimen Volume: 50 mL

Collection Instructions:

1. Collect urine for 24 hours.

2. No preservative.

3. Label specimens appropriately (60-mL bottle for protein electrophoresis and immunofixation and 6-mL tube for protein, total).

Additional Information:

1. 24-Hour volume is required.

2. See Urine Preservatives in Special Instructions for multiple collections.

3. If a serum specimen on the same patient will also be submitted, order MPSS / Monoclonal Protein Study, 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.
