2019 Novel Coronavirus (COVID-19) With Influenza A and Influenza B
Use
Results are for the identification and differentiation of RNA from SARS-CoV-2, Influenza A and Influenza B.
Special Instructions
Labcorp does not currently collect specimens for this test at their locations. Patients should have specimen collection performed at the healthcare facility where they receive treatment or testing orders. Specimens should then be sent to Labcorp using standard procedures for processing.
Limitations
The test is intended for use under the FDA's Emergency Use Authorization and has not been FDA cleared or approved. False negatives may occur depending on the timing of sample collection or variability in viral shedding. In such cases, test results should be interpreted in the context of clinical signs and symptoms as well as patient exposure history. Additionally, substances such as heparin, hemoglobin, ethanol, and EDTA at concentrations above 0.01M should not be present in specimens as these can inhibit PCR and potentially cause test failure.
