There are multiple collection devices that can be used for COVID-19 testing. DLO's preferred devices are the Nasopharyngeal and/or Oropharyngeal swab collected in a multi microbe media (M4) VCM, medium (green-cap) tube or equivalent (UTM). For a complete list of other acceptable collection devices, please view DLO's Specimen Collection Device Guidelines.

To meet the growing demand of our healthcare providers and patients, DLO and Quest Diagnostics have been rapidly expanding testing capacity by adding:

  • Test Code 39433: The Quest Diagnostics lab-developed test (LDT) to many of its other high-complexity laboratories including Chantilly, VA and Marlborough, MA. This test has been authorized by FDA under an EUA for use by authorized laboratories.
  • Test Code 39444: A high-throughput, FDA-Emergency Use Authorized Roche Diagnostics test for COVID-19, which is now available.
  • With the Roche test now available broadly, customers should be ordering the Roche test when submitting upper respiratory specimens. The Roche platform provides high-throughput automation, which will enable us to provide more testing capacity. For lower respiratory specimens, including bronchial lavage/wash (BAL), nasopharyngeal aspirate/wash, tracheal aspirate, or sputum, customers can still must order the LDT (test code 39433) for those specimen types.
  • Both tests codes available can utilize the nasopharyngeal (preferred) and/or oropharyngeal specimen types.

Providers should not refer any patients suspected (persons under investigation) or confirmed to be infected with COVID-19 to a DLO Patient Service Center or other phlebotomy site.

DLO will continue to provide test services for patients suspected (persons of interest) specimens collected in appropriate healthcare settings, such as physician offices and hospitals.

Providers should review the CDC website or contact their public health authority for information to guide their patient management and lab testing for COVID-19.

This is a changing situation and we will provide updates as our plans develop.

Yes. Specimens collected at physician offices, clinics or hospital settings may be forwarded per normal logistics processes to DLO.

Can patients order this directly, such as through DLO Direct?
No. A physician must order the test for a patient.
