Test ID: URIC    
Uric Acid, Serum

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

Uric acid is oxidized by uricase to form allantoin and hydrogen peroxide. The hydrogen peroxide reacts with TOOS (N-ethyl-N-[2-hydroxy-3-sulfopropyl]-3-methylaniline) and 4-aminophenazone in the presence of peroxidase to form a quinone-imine dye. The intensity of the red color formed is proportional to the uric acid concentration. Prior to the start of the reaction, the sample is initially incubated with a reagent mixture containing ascorbate oxidase and a clearing system. This eliminates any ascorbic acid present in the sample which could interfere with the peroxidase indicator reaction.(Package insert: Roche Uric Acid reagent, Roche Diagnostic Corp., Indianapolis IN, V10. 12/2018)

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

Monday through Sunday

Report Available The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

Same day/1 to 2 days

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

1 week

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