Test ID: DNSAG    
Dengue Virus NS1 Antigen, Serum

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

The InBios NS1 enzyme-linked immunosorbent assay (ELISA) is a 2-step sandwich-format colorimetric immunoassay for qualitative detection of nonstructural protein 1 (NS1) antigen in serum. Testing is performed according to manufacturer’s instructions on the Triturus automated EIA analyzer (Grifols, Miami, FL). Diluted patient samples and controls incubated in wells coated with purified capture antibody, specific for the dengue NS1 antigen. Following incubation, wells are washed, incubated with a horseradish peroxidase-conjugated polyclonal antibody specific to NS1 antigen and reincubated. Wells are subsequently washed and 3,3’,5,5’-tetramethlbenzidine substrate is added and incubated in the dark at room temperature. Stop solution is added next and the optical density (OD) of the reaction is measured at 450/620 nm. The immune status ratio (ISR) for each sample is calculated from the ratio of the OD obtained with the test sample divided by the OD from the calculated cutoff value (determined by the cutoff control sample).(Package insert: InBios DENV DetectTM NS1 ELISA, Seattle, WA)

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; 8 a.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 Clinic Laboratories until the release of the test result

7 days

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