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

The instrument used is a Vitros 350. Lactate in the specimen is oxidized by lactate oxidase to pyruvate and hydrogen peroxide. The generated hydrogen peroxide oxidizes the 4-aminoantipyrine, 1,7-dihydroxynaphthlaene dye system in a horseradish peroxidase-catalyzed reaction and results in a dye complex. Each mole of lactate oxidized results in 0.5 mole of the dye complex. The specimen is incubated at 37 degrees C for 5 minutes and the intensity of the dye complex is measured spectrophotometrically at 540 nm.(Package insert: Vitros Chemistry Products Instructions for Use - LAC, Version 7.0 Ortho-Clinical Diagnostics, Inc.

No

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

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 day

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

Rochester
