Test Code POWVU Powassan Virus, RNA, Molecular Detection, PCR, Random, Urine
Ordering Guidance
The Powassan virus polymerase chain reaction result may remain positive for a longer time in urine than in blood, serum, and cerebrospinal fluid (7 days or more).
Specimen Required
Container/Tube: Sterile container
Specimen Volume: 1 mL
Collection Instructions:
1. Collect random urine in a sterile container.
2. Label specimen as urine.
Useful For
Rapid testing for Powassan virus RNA (lineage 1 and lineage 2) using random urine specimens
An adjunctive test to serology for detection of early Powassan virus infection (ie, first few days after symptom onset).
This assay should not be used for screening asymptomatic individuals and should only be used to test patients with signs and symptoms of Powassan virus disease.
