Test ID BLOD1761 Dengue Virus, Molecular Detection, PCR, Serum

Useful For

Aiding in the diagnosis of acute infection caused by dengue virus

Specimen Type

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 polymerase chain reaction) and may require serologic testing (DENVP / Dengue Virus Antibody/Antigen Panel, Serum) to confirm the diagnosis of dengue virus infection.
