COVID-19 Antibody Test Near YouLast updated May 5, 2020
The COVID-19 antibody test, also known as a coronavirus antibody test, is a blood test that checks for the presence of SARS-CoV-2 (COVID-19) antibodies (IgG). In the near future, Accesa Labs will enable people who want the COVID-19 antibody test, also referred to as a coronavirus antibody test, to request this COVID-19 test through our affiliated doctor network, get tested at a local lab, and get electronic results quickly.
Until Accesa Labs has the COVID-19 antibody test available, you are welcome to request the test from Push Health, an affiliated telehealth network, and have your COVID-19 antibody testing performed using FDA-authorized antibody testing platforms (Abbott and EUROIMMUN). Through Push Health, you can request COVID-19 antibody testing online, after which your request will be routed to and, in most cases, approved by a licensed medical provider in your area. You will need to get your blood drawn at an affiliated lab location and, once available, your lab results will be available through your Push Health account. To get started, click here:
What Is Coronavirus?
When most people are referring to coronavirus today, they are referring to a strain of the virus named SARS-CoV-2 that originated in Wuhan, China. While coronavirus disease 2019 (COVID-19) is novel, there are attributes about it that are understood. COVID-19 is thought to spread between people through respiratory droplets from direct contact or when shared between people approximately six feet apart. Following an infection, symptoms of COVID-19 can appear within two weeks and primarily consist of fever, cough and shortness of breath. Older adults, pregnant women, and people with chronic medical conditions are also thought to be at higher risk.
What Is A COVID-19 Antibody Test?
The coronavirus antibody blood test (COVID-19 antibody test) is a new test that helps check for antibodies in the blood to the novel coronavirus. This COVID-19 lab test is sometimes known as a coronavirus serological test. People who have already been infected and recovered from SARS-CoV-2 will sometimes generate antibodies to COVID-19. These COVID-19 IgG antibodies are detectable in the blood - typically within 10-14 days - using serological testing. It is important to note that the relationship between IgG positivity and immunity to SARS-CoV-2 has not yet been firmly established. Similar titer tests are already in use when screening workers for communicable diseases such as hepatitis B, measles, mumps, rubella (collectively tested as the MMR titer), and varicella.
Accesa Labs will be offering this test in the near future. In the meantime, you are welcome to request the test from Push Health, an affiliated telehealth network. Through Push Health, your request will be routed to and, in most cases, approved by a licensed medical provider in your area. You will need to get your blood drawn at an affiliated lab location and, once available, your lab results will be available through your Push Health account. Please note that people who are currently having symptoms related to COVID-19 should not get this test and should seek medical care with a medical professional instead. To get started, click here:
Coronavirus Antibody Test Process
Similar types of antibody tests are performed through a simple blood draw. Once the blood is drawn, the specimen is analyzed to check if antibodies exist in the blood. In the case of a COVID-19 antibody test, the blood test checks for antibodies that may indicated a past exposure to COVID-19 / SARS-CoV-2. When they develop, COVID-19 IgG antibodies can take up to 14 days to develop after an infection. At this time, the relationship between the presence of COVID-19 IgG antibodies and immunity to SARS-CoV-2 has not yet been firmly established.
COVID-19 Antibody Test Results
As per the information provided by Quest, a description of how these COVID-19 antibody test results can be evaluated is as follows:
"Detection of IgG antibodies may indicate exposure to SARS-CoV-2 (COVID-19). It usually takes at least 10 days after symptom onset for IgG to reach detectable levels. An IgG positive result may suggest an immune response to a primary infection with SARS-CoV-2, but the relationship between IgG positivity and immunity to SARS-CoV-2 has not yet been firmly established. Antibody tests have not been shown to definitively diagnose or exclude SARS-CoV-2 infection. Diagnosis of COVID-19 is made by detection of SARS-CoV-2 RNA by molecular testing methods, consistent with a patient's clinical findings."
"This test has not been reviewed by the FDA. Negative results do not rule out SARS-CoV-2 infection particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals. Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status. Positive results could also be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E. This test is not to be used for the screening of donated blood."

FDA Authorization - COVID-19 Antibody Testing
This antibody test is run using Abbott or EUROIMMUN equipment with FDA Emergency Use Authorization (EUA) for SARS-CoV-2 IgG testing. The FDA grants EUA for testing after reviewing validation studies. Abbott received FDA Emergency Use Authorization on April 26, 2020 for testing on the ARCHITECT i1000SR and i2000SR systems. EUROIMMUN received FDA Emergency Use Authorization on May 4, 2020.
FDA - Emergency Use Authorization
Why is FDA oversight over COVID-19 antibody testing important? The FDA helps oversee lab tests to make sure they demonstrate validity to protect the public. Because COVID-19 testing is relatively new, the FDA, in balancing the need for COVID-19 antibody testing with lack of long-term data, has applied the "Emergency Use Authorization" to a handful of tests pending more robust data.
COVID-19 Antibody Test For Companies / Organizations
Accesa Labs manages testing for dozens of corporations and organizations. If you represent a company or organization and need access to a corporate portal to manage testing for your employees or staff, please submit your information on our organizations page.
COVIDS-19 Antibody Testing - More Information
What is serological testing?
Serological testing, whether it pertains to COVID-19 serology or other types of testing, involves studying the serum to analyze components of it, including antibody levels.
What does an antibody do?
An antibody is a protein that is found in the blood. Antibodies are part of a surveillance system - the immune system - that is responsible, among other things, for looking for foreign invaders (generically called an antigen) like a virus or other infection. Antibodies are specifically made to fit different types of antigens and their unique structures. In the case of coronavirus, the presence of COVID-19 antibodies may suggest an immune response to the illness.
Why would I have antibodies to a virus in my blood?
In general, people often have antibodies in the blood as a consequence of a meaningful past exposure to a virus - either through a prior infection or a vaccination. The antibodies are sentinels that are part of the memory of the immune system and allow the body to mount a meaningful attack against a virus should it encounter it again. However, it is important to know that simply having antibodies to a virus does not necessarily mean that one is immune if one had inadequate numbers or antibodies that do not work well. Also, viruses are good at hiding within the body in places where they cannot always be reached by antibodies such as inside of cells.
How would I get COVID-19 antibodies in my blood?
In the case of COVID-19, the current theory is that some people may develop IgG antibodies, typically after 14 days, as a result of having had COVID-19. At this time, the relationship between antibodies detected using a COVID-19 antibody test and immunity to SARS-CoV-2 is not fully understood. Said another way, we do not understand if simply having coronavirus antibodies or what level of antibodies (if any) would provide immunity to getting COVID-19 in the future.
How long will COVID-19 antibodies in the body?
It is unknown how long COViD-19 antibodies, if they even develop, will last in the body. In studying other coronaviruses, SARS-specific antibodies were maintained for an average of two years.
How is accuracy measured in an antibody test?
Initial validation of antibody testing utilizes statistical concepts known as sensitivity and specificity. Sensitivity refers to the true positive rate while specificity refers to the true negative rate.
