Test name:

Test number:

994

Excellian order number:

LAB994

Abbreviation:

MSO

Alternate names:

Powassan
Powassan virus
Powassan Virus, PCR, CSF
POWVC

Useful for:

Rapid testing for Powassan virus RNA (lineage 1 and lineage 2) using cerebrospinal fluid 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.
