COVID-19 Healthcare Provider Information

Important Information for Providers

DLO provides our healthcare providers with the latest on COVID-19 testing and collection information.

COVID-19 Molecular Test Code

  • Test Code 39448: SARS-CoV-2 RNA (COVID-19), Qualitative NAAT - This test is a qualitative multi-target molecular diagnostics test that aids in the detection of COVID-19.

There are multiple collection devices that can be used for COVID-19 PCR testing. DLO's preferred collection device is the Anterior Nares (AN) collection swab. Other common collection 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.

Since the beginning of 2021, Quest Diagnostics has launched three new SARS-CoV-2 (COVID-19) antibody tests, two semi-quantitative spike protein specific tests, and a qualitative nucleocapsid protein specific test.

COVID-19 IgG and IgG/IgM Test Codes

  • Test Code 34499: SARS-CoV-2 Antibody (IgG), Spike, Semi-Quantitative - This test helps identify individuals with antibodies to the SARS-CoV-2 (COVID-19) spike protein. The semi-quantitative test provides a numerical result, with a level of 1.0 or more as a positive result, indicating an immune response to SARS-CoV-2.
  • Test Code 39749: SARS-CoV-2 Antibody (IgG), Nucleocapsid, Qualitative test - This test is a nucleocapsid protein specific test to detect an immune response to a recent or prior infection with SARS-CoV-2.
  • Test Code 31672: SARS-CoV-2 Antibody (IgG, IgM) panel - This test expands on the IgG antibody offering to include IgM detection. The panel provides for the qualitative detection of IgM and IgG antibodies to SARS-CoV-2, with separate results provided for IgM and IgG.

Providers should not refer any patients with active COVID-19 symptoms to a DLO Patient Service Center or other phlebotomy site for specimen collection, but DLO is able to do observed swab collections for patients who don't have active symptoms, as well as blood collections for serology testing.

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.

For more information, please download the DLO COVID-19 Molecular and Serology Testing Information Sheet.

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.
