Our labs process samples seven days a week. Presence of the specific organism nucleic acid may be confirmed by performing a melting curve analysis of the amplicon. Furthermore, the viruses may not be detected if the sample is not collected as directed. On samples collected from regions where Lyme disease is endemic, seroprevalence for POWV in TBD samples was 9.4% (10 of 106) versus 2% when tested with non-TBD samples (2 of 100, P = 0.034). If you have reason to believe you have been exposed, it is important to follow up with a healthcare provider for further evaluation, get re-tested, and follow isolation or quarantine precautions as recommended.

Additional information regarding LOINC codes can be found at LOINC.org, including the LOINC Manual, which can be downloaded at LOINC.org/downloads/files/LOINCManual.pdf. Powassan is a rare, but often serious disease that is caused by a virus spread by infected ticks. Unauthorized use of these marks is strictly prohibited. Although there is no targeted antiviral therapy and treatment is entirely supportive care, diagnosis is important for a number of reasons, including the ability to discontinue empiric antibiotics and to provide prognostic information for patients and families. It is common for RT-PCR and serology to be used together for diagnosis of early infection, as they are complementary methods. Gross contamination; severe hemolysis; icteric serum; lipemic serum; quantity not sufficient for analysis. After 7 days, POWV RT-PCR is less sensitive and serologic testing is the preferred diagnostic method.
