A Biospecimen Project to Retrieve Retrospective Plasma Samples Collected from Patients with Dengue Fever. Assessment of the reactivity pattern of samples from tropical Africa with candidate Dengue prototype assays and with assays addressing potentially cross-reactive agents.
This is a research project with samples provided by Muhimbili National Hospital Laboratory, Dar es Salaam, Tanzania from their routine laboratories. Sample size 160. Testing: All samples to be PCR tested positive using an FDA approved or CE marked assay.
Confirmation that at least 1-2mls of plasma is available for the project. All immunoassay testing/validation measurements were performed at Roche Diagnostics in Penzberg (Germany), as evaluation immunoassays composed of the candidate antigens, which are not commercial products.
