12PTU - Performance: Protein, Total, 12 Hour, Urine

Test Catalog

Test ID: 12PTU    
Protein, Total, 12 Hour, Urine

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

The pyrogallol red dye is combined with molybdenum acid, forming a red complex with maximum absorption at 470 nm. When this complex is combined with protein under acidic conditions, its maximum absorption is shifted to a longer wavelength and develops a blue-purple color with a maximum at 604 nm. The concentration of protein in the specimen is equivalent to the absorbance of the dye urine mixture measured at 600 nm.(Package insert: QuanTtest Red Total Protein Assay System, Quantimetrix, Redondo Beach, CA, 4/13)

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.

Monday through Sunday; Continuously

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

Same day/1 day

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

7 days

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