Tracking COVID-19 Variants
Labcorp has been regularly tracking variants of the virus throughout the pandemic. The sensitivity of our PCR test is not impacted by these variants. We have been working with the Centers for Disease Control and Prevention (CDC) to provide sequencing of samples of SARS-CoV-2, the virus that causes COVID-19. Our tests remain effective against variants like Omicron and Delta. This is because they are designed to identify segments of the genetic code that are the least likely to mutate. For more information on variants, see our Viral Variation 101 post or read our Guide to Variants.

It is not yet determined what level of antibodies (to the SARS-CoV-2 spike protein) correlate to immunity against developing symptomatic SARS-CoV-2 disease. Studies are underway to measure the quantitative levels of specific SARS-CoV-2 antibodies following vaccination. Such studies will provide valuable insights into the correlation between protection from vaccination and antibody levels.
Labcorp currently offers several options for COVID-19 tests that identify if individuals are infected or may have been infected with coronavirus. This infographic was developed to help you determine which test is right for you. If you are experiencing symptoms of COVID-19, please contact your healthcare provider.
COVID-19 IgG antibody test collections (blood draw) are available through our patient service centers, including Labcorp at Walgreens locations. This type of COVID-19 test is for individuals who think they may have had COVID-19 and do not have symptoms. Individuals have the ability to receive the COVID-19 IgG antibody test from their doctor, in person or through a telemedicine program, and now directly using www.Labcorp.com/antibody-testing.
Select Labcorp patient service centers also offer specimen collection for COVID-19 PCR testing to individuals who are symptom-free and who have not been exposed to COVID-19. If you have COVID-19 symptoms, please consult your physician or other healthcare provider.
