Test Name

Test ID: REPU    
Electrophoresis, Protein, Random, Urine

Method Description Describes how the test is performed and provides a method-specific reference

Urine proteins are separated in an electric field according to their size, shape, and electric charge (Helena SPIFE 3000). The separation is performed on agarose gels (Helena SPIFE SPE Vis Gel). The proteins are visualized by staining with acid blue and the intensity of staining is quantitated by densitometry (Helena Quick Scan Touch). Multiplying by the urine protein concentration (Benzethonium Chloride) converts the percentage of protein in each fraction into urine concentration.(Kyle RA, Katzmann JA, Lust JA, Dispernzieri A: Immunochemical characterization of immunoglobulins.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Total Protein: Monday through Sunday; Continuous

Protein Electrophoresis: Monday through Saturday; 12 p.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

3 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

See Individual Unit Codes

Performing Laboratory Location The location of the laboratory that performs the test
