DLO can now collect COVID-19 PCR specimens for asymptomatic patients at most DLO Patient Service Centers throughout Oklahoma. Patients with active COVID-19 symptoms should go to a healtchare provider or pharmacy drive-thru for specimen collections. Please do not go to a DLO location if you have active symptoms.

Where to get tested for COVID-19

Testing for COVID-19

Through our relationship with Quest Diagnostics, DLO began PCR testing for COVID-19 on March 9, 2020. As of April 21, DLO began providing COVID-19 SARS-CoV-2 immunoglobulin G (IgG) antibody serology test which can identify individuals who have developed a serological response. The PCR test specimen collection is to be performed only using respiratory specimens collected from individuals who meet CDC clinical and/or epidemiological criteria for COVID-19 testing. DLO Patient Service Centers and other phlebotomy sites cannot collect specimens for the PCR test, but the IgG serology test is a routine blood collection and can be drawn at a DLO location with a provider's order.

Patients: Most DLO Patient Service Centers can collect for COVID-19 PCR testing as long as you are asymptomatic. If you have active COVID-19 symptoms, please contact your healthcare provider and do not go to a DLO location for specimen collection.
