COVID-19 (SARS-CoV-2)/FLU/RSV Nucleic Acid Test, Nasopharyngeal
COVID-19; SARS-COV-2, FLU A, FLU B, Respiratory Syncytial Virus, Influenza
Molecular Diagnostics Laboratory
Clinical Indication and Relevance
The assay is useful to detect SARS-CoV-2 (COVID-19), Influenza A (Flu A), Influenza B (Flu B) and/or Respiratory Syncytial Virus.
The assay uses polymerase chain reaction (PCR) on the GeneXpert Xpress System.
Minimum Specimen Requirements
Collect a nasopharyngeal (NP) swab according to instructions provided with the kit
in either viral transport media (VTM) or universal transport media (UTM).
The specimen must be labeled with two identifiers at the time of collection. Examples of acceptable identifiers include but are not limited to: patient name, date of birth, hospital medical record number, accession number. A location (e.g., hospital room number) is not an acceptable identifier. Collection date and collector’s identifier are required.
A completed requisition form should be submitted with every sample and, at minimum, the following is required: ordering physician name, phone number, fax number, and patient’s name, identifying number of patient, patient sex, patient date of birth specimen type, collection date, tests requested, provisional diagnosis or clinical rationale for test, and billing information.
Specimens can contain extremely high levels of virus or other organisms. Specimens
must be shipped and transported in accordance with applicable local, national and international transportation regulations. Maintain proper storage conditions of 2-8°C during shipping to ensure integrity of the specimen.
After collection, store samples at 2-8°C up to 7 days before testing.
Improperly labeled or incorrect patient identification, specimen leaked,
incorrect media, insufficient volume (less than 700 ul), no swab, bloody or grossly mucoid, specimen does not meet transport, storage or date of collection requirements.
1-2 business days.
