DLO OFFERS COVID-19 IgG antibody serology testing in Oklahoma

In addition to COVID-19 PCR testing for active infections, DLO now offers a serologic test to detect IgG antibodies for COVID-19. 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 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. Visit dlolab.com/covid-19 for more information.


Due to low patient volume during the COVID-19 outbreak, some DLO locations have reduced operating hours, including one location that is temporarily closed. DLO wants to remind our patients that PCR specimen collection for active COVID-19 infections must be done in a clinic setting such as a doctor's office or hospital. We do not collect COVID-19 PCR specimens in our patient service centers. If you have symptoms, please call your healthcare provider and do not visit a DLO lab.

DLO would also like to encourage our patients to schedule an appointment to help reduce your wait time. To make an appointment and view the new operating hours, visit dlolab.com/locations and click the "Make an Appointment" link on the site you want to visit. We apologize for any inconvenience and appreciate your understanding during this challenging time.
