There are multiple collection devices that can be used for COVID-19 PCR 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 PCR Specimen Collection Device Guidelines.

To meet the growing demand of our healthcare providers and patients, Quest Diagnostics has rapidly expanded testing capacity with the addition of both the Roche Diagnostics high-throughput test and the Quest Diagnostics lab-developed test (LDT) running simultaneously in many of our laboratories across the country for PCR testing.

  • Test Code 39448: Healthcare professionals can now order COVID-19 testing using a single code—39448. The new test code authorizes DLO/Quest to select which test type to perform and result—the FDA-Emergency Use Authorized Quest Diagnostics lab-developed test (LDT), the FDA-Emergency Use Authorized Roche Diagnostics test, or any subsequent similar PCR detection test platforms Quest introduces for COVID-19. Ordering COVID-19 testing with a single code allows DLO and Quest to more efficiently distribute testing to whichever platform offers the most access at a given time. Both tests can utilize the nasopharyngeal (preferred) and/or oropharyngeal specimen types.
  • The 39448 tests code 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.

Test Code 39504: Healthcare professionals can now order a serologic test to detect IgG antibodies. By offering serological testing, DLO can work with providers to identify individuals who may have been exposed to the SARS-CoV-2 virus and are likely to have developed an immune response. Knowing whether your patients and/or healthcare staff have had prior exposure, and may have developed immunity, can offer them the peace of mind and the insight necessary to make a more informed decision about their return to work and/or activity. This insight also helps to minimize the risk of continued spread of COVID-19. Specimens for IgG testing can be collected at a DLO Patient Service Center or by a DLO in-office phlebotomist.

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.
