NASOPHARYNGEAL: Insert a flexible mini-tip swab through the nostril into the nasopharynx. Rotate gently and withdraw. Place swab into Universal Transport Media. NARES: Insert a flexible mini-tip swab or regular swab 1-2cm into one of the anterior nares. Rotate the swab against the nasal mucosa for about 3 seconds and withdraw. Repeat with the other anterior nare using the same swab. Place swab into Universal Transport Media.
Storage/Transport Temperature
Refrigerate
Unacceptable Conditions
Inappropriate specimen type (throat or sputum), inadequate volume, inappropriate transport device (including ESwab, leaking specimen.
Stability (from collection to initiation)
Ambient: Nasopharyngeal/Nasal specimens are stable in VTM/UTM for up to 48 hours room temperature.
Refrigerated: Nasopharyngeal/Nasal specimens are stable in VTM/UTM for up to 7 days refridgerated.
Frozen: Nasopharyngeal/Nasal specimens are stable in VTM/UTM for up to 1 month.
Remarks
SARS-CoV-2 (2019-nCoV) is the virus which causes the disease named "coronavirus disease 2019" (abbreviated "COVID-19").
Performed
Monday-Sunday
Reported
Froedtert Inpatient and Emergency room: 6 hours
Outpatient: 24 hours
Methodology
Real Time Polymerase Chain Reaction (PCR) Amplification
Reference Interval
Not Detected
Interpretive Data
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions.
Test performed using Cepheid Xpert Xpress SARS-CoV-2/Flu/RSV assay. Cepheid Xpert Xpress SARS-CoV-2/Flu/RSV is a real-time PCR assay intended for the qualitative detection and differentiation of SARS-CoV-2 (COVID-19), influenza A virus, influenza B virus, and/or respiratory syncytial virus (RSV) nucleic acid. This assay has Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration for specimens collected from individuals suspected of respiratory viral infection consistent with COVID-19. Test performance characteristics were determined by the Wisconsin Diagnostic Laboratories Microbiology/Molecular Department. This laboratory is certified under the Clinical Laboratory Improvements Amendment of 1988 (CLIA) as qualified to perform high complexity clinical laboratory testing.
