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. Diluted patient samples and controls are 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; InBios International, Inc; Revision 1/26/2015)

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.


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 7 days

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