HelpTest ID DENGS Dengue Virus, Molecular Detection, PCR, Serum
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 PCR) and may require serologic testing (DENVP / Dengue Virus Antibody/Antigen Panel, Serum) to confirm the diagnosis of dengue virus infection.
Specimen Required
Collection Container/Tube:
Preferred: Serum gel
Acceptable: Red top
Submission Container: Sterile container
Specimen Volume: 0.5 mL
Collection Instructions:
1. Collect whole blood in a serum gel tube.
2. Centrifuge and aliquot the serum into a sterile container within 6 hours of collection.
3. Label specimen as serum.
Useful For
Aiding in the diagnosis of acute infection caused by dengue virus
Highlights
Detection of dengue virus nucleic acid in serum is suggestive of recent exposure and acute infection with dengue virus.
The presence of dengue virus nucleic acid in serum can be used as a marker for acute-phase infection. 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 to confirm the diagnosis of dengue virus infection.
