Test Code DENGC Dengue Virus, Molecular Detection, PCR, Spinal Fluid
Ordering Guidance
The presence of dengue virus nucleic acid in cerebrospinal fluid (CSF) or serum (as detected by molecular assays [This test or DENGS / Dengue Virus, Molecular Detection, PCR, Serum] overlaps with the presence of dengue virus nonstructural protein 1 (NS1) antigen (DNSAG / Dengue Virus NS1 Antigen, Serum). Patients with a history of symptoms for more than 1 week may be negative by molecular tests (ie, real-time PCR) and may require serologic testing (DENVP / Dengue Virus Antibody/Antigen Panel, Serum) to confirm the diagnosis of dengue virus infection.
