HelpTest ID DENGS Dengue Virus, Molecular Detection, PCR, Serum
Method Name
Real-Time Reverse Transcription Polymerase Chain Reaction (RT-PCR)
Ordering Guidance
The presence of dengue virus nucleic acid in 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.
