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.

Expected 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.
