Test ID: NOXB    
Neutrophil Oxidative Burst, Blood

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

Neutrophil oxidative burst is a functional assay that measures the oxidation (and resultant fluorescence) of dihydrorhodamine 123 (DHR 123) due to oxygen radical generation during the oxidative burst. The DHR 123 is preloaded into the cells, PMA (phorbol 12-myristate 13-acetate) is added to stimulate the neutrophils, and the neutrophil fluorescence is quantitated as the blood is analyzed on a flow cytometer.

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 Friday

Do not send specimen after Thursday. Specimen must be received by 10 a.m. on Friday.

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.

3 days

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

4 days

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