Specificity Study of Diagnostic for Early Detection of Dengue Infection

This study assesses the specificity of DENV Detect™ NS1 ELISA versus standard reference tests (e.g. PCR or viral culture) for dengue diagnosis in the US.

DENV Detect™ NS1 ELISA serves as an aid in the clinical laboratory diagnosis of early stages of Dengue infection in patients with clinical symptoms consistent with Dengue infection. This test is intended to be used on sera obtained within the first 7 days of symptoms. DENV Detect™ NS1 ELISA and rapid test results (positive or negative) must be confirmed by testing with a reference standard test.

This study will use archived, leftover human serum samples that have been sequentially collected from areas non-endemic for Dengue infection. Each specimen must have been collected within the first 7 days of symptoms, and must be accompanied by clinical data demonstrating that the individual had symptoms consistent with Dengue infection. The samples will have no personally identifiable information.

ELISAs and reference tests will be performed by different operators who are laboratory staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently.

Primary Outcome Measures:
  • number of subjects with negative result [ Time Frame: one day ]

Biospecimen Retention:   Samples Without DNA

Enrollment: 300
Study Start Date: August 2012
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Human males and females of varying ages and geographical locations where dengue fever is non-endemic. We will use retrospective (archived) human serum samples, not collected specifically for this study and not individually identifiable to the Investigators. These samples will fall under the category of "leftover" specimens as described by FDA guidance. These archived samples will have been collected from patients within 7 days after onset of symptoms consistent with Dengue infection.

Inclusion Criteria:

  • All age groups and both sexes.
  • Serum samples collected within 1- 7 days of onset of symptoms consistent with Dengue virus infection.
  • Information must be available about symptoms, age, and sex of patients from which samples are collected.

Exclusion Criteria:

  • Any sample(s) with linked personal identifiers or any sample for which personal information can be discovered will be excluded.
