2019 Novel Coronavirus (COVID-19) With Respiratory Syncytial Virus, NAA
Also known as: 2019 Novel Coronavirus, COVID-19, Respiratory Viral panel, SARS-CoV-2
Use
Results are for the identification and differentiation of RNA from SARS-CoV-2 and RSV.
Special Instructions
Labcorp does not collect specimens for this test. Patients should not visit Labcorp locations for specimen collection. Specimens must be collected at the healthcare facility where the test is ordered. The specimen should then be sent to Labcorp via standard procedures. Results are typically reported electronically, allowing for faster delivery. Collection and shipping must adhere to guidelines to ensure the specimen's integrity and timely results.
Limitations
The assay is authorized under the FDA's Emergency Use Authorization for the detection of SARS-CoV-2 and RSV. It is not FDA cleared or approved but is permitted for use due to the ongoing public health emergency. Negative results do not rule out the possibility of infection, especially if exposure to the virus has occurred recently or if symptoms are present. Analytical sensitivity may be affected by variations in viral mutations, although no impact has been observed to date.
