Frequently Asked Questions


  • Does the PCR (molecular) test detect ‘newer’ strains of the virus?

    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.

  • What do the results of a semi-quantitative antibody test mean in respect to immunity?

    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.

  • I may have been exposed to COVID-19. What should I do?

    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.

  • Can I visit one of Labcorp’s patient service centers and request a COVID-19 test?

    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

    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.

    * For information on how to request an at-home collection test kit to detect an active COVID-19 infection, visit Pixel by LabcorpTM.

  • How do I know if I need to be tested?

    The Centers for Disease Control and Prevention (CDC) recommends that you contact your healthcare provider if you are experiencing symptoms such as fever, cough and shortness of breath; if you’ve been in contact with a person who has COVID-19; or if you have traveled recently from an area with sustained, ongoing transmission.

  • How long will it take for Labcorp to report results?

    The current average time to deliver results for the COVID-19 swab test is 1-2 days from the date of specimen pickup. 

    For the COVID-19 IgG antibody test, the average delivery of test results is 1-3 days from the date of specimen pickup.

  • I have an appointment or would like to visit a patient service center for another type of test. Are you still open?

    Yes, most of our centers remain open. For specific opening hours and locations, visit our labs and appointments page.

  • What are Labcorp prices for COVID-19 testing?

    Labcorp will bill the individual’s health insurance for the cost of the testing for consumers who meet clinical testing guidelines. Physician fees are separate and charged to the consumers by the doctor, telemedicine or healthcare provider.

    The list price for COVID-19 PCR testing performed by Labcorp is $100, and the list price for COVID-19 antibody testing is $42.13. The list price for combined respiratory testing varies from $166 to $266, depending on the testing combination your physician orders. For combined testing that includes COVID-19, influenza A & B, and respiratory syncytial virus, the list price is $266. For combined testing that includes COVID-19 and influenza A & B, the list price is $196. For combined testing that includes influenza A & B and respiratory syncytial virus, the list price is $166.
