- Due to a nationwide shortage of rapid testing reagents, this rapid PCR test will only be available to hospital patients.
- Tests positive for influenza or RSV outside of respiratory virus season (generally May through October) must be confirmed by a second method. Specimens will be sent to MDHHS for confirmation.
Specimen Collection Criteria
Collection instructions For Nasopharyngeal specimens:
- Collect: Nasopharyngeal (preferred) or nasal swab in viral transport media (i.e. M4-RT, M5, UVT, UTM).
- Specimen Collections Manual: Nasopharyngeal (NP) Specimens,
- Place the swab into viral transport media and make sure that the cap is tightly sealed.
- Specimens sent through the pneumatic tube system must be double bagged and both bags must be completely sealed.
Physician Office/Draw Specimen Preparation
Maintain all specimens refrigerated (2-8°C or 36-46°F) prior to transport.
Preparation for Courier Transport
Transport: Nasopharyngeal or nasal swab in viral transport media, refrigerated (2-8°C or 36-46°F).
Preparation for Intra-Hospital Transport:
Specimens sent through the pneumatic tube system should be double bagged and completely sealed.
- Dry swabs.
- Specimens in non-sterile or leaking containers.
- Cotton/calcium alginate swabs or swabs with wooden shafts
- Contaminated media (e.g. yellow in color or contain black particles
Specimens are stable for eight (8) hours at room temperature (20-26°C or 68-78.8°F).
Specimens may also be refrigerated (2-8°C or 36-46°F) prior to testing.
Specimen Stability for Testing:
Room Temperature (20-26°C or 68-78.8°F): 48 hours
Refrigerated (2-8°C or 36-46°F): 7 days
Frozen (-20°C/-4°F or below): 7 days
Specimen Storage in Department Prior to Disposal:
Frozen (2-8°C or 36-46°F): 7 days (negative samples only)

Not Detected: No SARS-CoV-2, influenza A, influenza B, or RSV RNA detected.
Nucleic Acid Amplification (NAA) / Polymerase Chain Reaction (PCR). The SARS-CoV-2 (COVID-19) test is for in vitro diagnostic use under the FDA Emergency Use Authorization (EUA) for US laboratories certified under CLIA to perform high complexity testing. This test has not been FDA cleared or approved.
This assay determines the presence of SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus (RSV) in a respiratory specimen. Nucleic acid amplification testing is the optimal diagnostic modality for detection of respiratory viruses.
Symptoms of a respiratory virus infections may include fever, cough, sore throat, and malaise, which is also seen in patients with COVID-19. Due to the differences in patient treatment and management, it is necessary to differentiate COVID-19 from other common respiratory infections. This assay detects and differentiates SARS-CoV-2 (COVID-19), influenza A, influenza B, and respiratory syncytial virus (RSV).
Symptoms of SARS-CoV-2 (CoVID-19) infection are similar to those of other respiratory viruses that occur seasonally in the fall/winter and include:
Shortness of breath
Respiratory viruses typically follow a seasonal pattern with an increase of infections beginning in the fall and winter.
- As an emerging pathogen, the seasonal pattern of SARS-CoV-2 is currently unknown
- Most cases of influenza occur in the winter and early spring (January through April) with peak incidence in January and February.
- RSV is present yearly, showing up in the early fall and causing morbidity until late spring.
SARS-CoV-2: According to estimates from the World Health Organization (WHO), the incubation period for SARS-CoV-2 ranges from 2 – 14 days with a median incubation period of 5 days. Patients are infectious 1-2 days before the onset of symptoms and up to 10 days thereafter. Immunocompromised and critically ill patients may shed infectious virus for longer periods of time.
Influenza and RSV: The incubation period is 18-70 hours. Patients are infectious one day before the onset of symptoms and for 3-4 days thereafter. Infants and immunocompromised patients may shed infectious virus for longer periods of time.
These viruses are very contagious and are transmitted through inhalation of virus-laden aerosols or by autoinoculation after handling fomites contaminated with nasal or throat secretions.
