HelpTest ID DENGC Dengue Virus, Molecular Detection, PCR, Spinal Fluid
Ordering Guidance
The presence of dengue virus nucleic acid in cerebrospinal fluid or 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 polymerase chain reaction) and may require serologic testing (DENVP / Dengue Virus Antibody/Antigen Panel, Serum) to confirm the diagnosis of dengue virus infection.
