Test Details
Methodology
Nucleic Acid Amplification (NAA)
Result Turnaround Time
1 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Results are for the identification and differentiation of RNA from SARS-CoV-2, Influenza A, Influenza B and RSV.
Special Instructions
Please note: Labcorp does not currently collect specimens for this test. Patients for whom testing has been ordered should not be sent to a Labcorp location to have a specimen collected. Instead, an appropriate specimen should be collected at the health care facility where the patient was seen and the test was ordered. The specimen should be sent to Labcorp using standard procedures.
Please note: It takes approximately 1 - 3 days from the date of pickup of a specimen for testing to the release of the test result to the health care provider. Test results are most typically reported electronically, which generally allows for faster delivery. This time frame can vary based on demand, the length of time to transport the specimen to Labcorp's test facilities, and the prioritization of the patients (as defined by heath care authorities and the White House Coronavirus Task Force, HHS and other health authorities). Labcorp is working continuously to support the needs of health care workers, patients, government, clients and other organizations, and expects capacity to continue to increase.
We have been regularly tracking mutations of the virus throughout the pandemic to determine the impact it would have on our test sensitivity. To date, we have not seen any impact.
Limitations
This assay is intended for use only under the Food and Drug Administration's Emergency Use Authorization for COVID-19 testing.
For Flu A+B and RSV testing: This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Specimen Requirements
Specimen
Anterior nasal swab; nasopharyngeal swab, mid-turbinate swab
Volume
1 - 3 mL
Minimum Volume
1 mL (Note: This volume does not allow for repeat testing.)
Container
Anterior nasal swab, nasopharyngeal (NP) swab or mid-turbinate swab in viral/universal transport medium (VTM/UTM) or 0.9% saline
Collection Instructions
Nasopharyngeal (NP) and mid-turbinate swabs: Collect using standard techniques. Place the swab into VTM/UTM and cap tightly.
Anterior nasal swab: Insert the tip of the swab into one nostril. The swab does not need to be inserted far. Insert just until the tip of the swab is no longer visible. Rotate the swab in a circle around the entire edge of your nostril at least three times. Repeat with the second nostril. Insert swab into the 0.9% saline tube and cap tightly.
Stability Requirements
Temperature | Period |
---|---|
Room temperature | 72 hours |
Refrigerated | 72 hours |
Frozen | > 72 hours |
Storage Instructions
Frozen at -20° C (preferred). Refrigerated specimens and room temperature specimens (if received for testing within 72 hours of collection) are also acceptable.
Causes for Rejection
Unacceptable specimens include specimens that are beyond the established stability, improperly labeled, grossly contaminated, broken or with significant leakage in transit or improperly collected or shipped. Substances inhibitory to PCR should not be used to collect specimens; known inhibitory substances include heparin, hemoglobin, ethanol, EDTA concentrations > 0.01M. Specimens must be submitted with a swab.
