Learn MoreHow does T-Detect COVID work?
T cells are the first responders of the adaptive immune system and activate the antibody response. While antibodies to SARS-CoV-2 (the virus that causes COVID-19) naturally wane and are detectable in the shorter term, T cell responses can persist in the blood long after antibody responses wane.1,2,4
The T-Detect COVID test can detect T cells in a blood sample that can remain for up to several months after symptoms appear.1,2,3
What does the T-Detect COVID test measure?
The T-Detect COVID test can detect an immune response to SARS-CoV-2, the virus that causes COVID-19 disease, to assess recent or past infection. It is not intended for the diagnosis of active/current SARS-CoV-2 infection.
T cells are key players in the adaptive immune system. When the body is invaded by a foreign substance like a virus or bacteria, the immune system begins to rally one of its earliest lines of defense, helper T cells, to join the fight.
Helper T cells may call on their allies to kickstart antibody production to support the fight against the disease. Helper T cells also alert other types of T cells to the presence of foreign invaders to be targeted and destroyed.
After the body has fought off an infection or disease, a small number of T cells remain in the blood. They are called memory T cells and their job is to remember how to ward off these invaders if they ever return.
How accurate is the T-Detect test for COVID-19?
When the T-Detect COVID test was compared with serology testing:
What does the T-Detect COVID test mean in regard to immunity?
A T cell response is typically detectable in blood several days after initial infection. How long this response lasts post-infection and the implications for immunity are not known. In one study, T cells were shown to persist in the blood for more than six months after initial infection and studies of other coronaviruses show T cell responses can persist for several years.1,2,3
To protect yourself and others, the CDC recommends you wear a mask, stay at least six feet from others whom you don’t live with, avoid crowds and wash your hands often with soap and water for at least 20 seconds (especially after you have been in a public place or after blowing your nose, coughing, or sneezing).
Who should take this test?
The T-Detect COVID test can help you understand if you’ve had a recent or past COVID-19 infection.
The T-Detect COVID test can provide answers in these situations:
The test is also appropriate for those interested in supporting COVID-19 research.
The T-Detect COVID test is not meant to diagnose an active infection.
If I have a positive T-Detect COVID test, do I need to get a vaccine?
Please consult your doctor regarding whether you should be vaccinated against SARS-CoV-2. As of January 25, 2021, the CDC recommends vaccination for most people, even if they have had a natural infection with SARS-CoV-2.1
Can a T cell test be used in place of, or in addition to, a PCR/antigen test?
T-Detect COVID is used to detect a recent or past COVID-19 infection. PCR/antigen tests are used to diagnose a current COVID-19 infection. Talk to your doctor about which test is right for you.
How long will it take to get results?
Estimated time for results is 7-10 days from shipment of blood sample (including 5-7 days for lab processing). Lab processing begins once all required provider and patient information is validated.
What will results look like?
The T-Detect COVID test results are a positive or negative result. A positive result means there was a recent or past exposure to SARS-CoV-2, the virus that causes COVID-19. A negative result indicates that past exposure to SARS-CoV-2 probably did not occur.
T-Detect COVID has been shown to have high sensitivity. However, in certain circumstances, including but not limited to the number of days since infection, the test may be negative despite a prior SARS-CoV-2 infection.
If I got the COVID-19 vaccine, will it affect my T-Detect COVID results?
We do not currently have information on how the SARS-CoV-2 vaccine may affect the T cell response and the results of the T-Detect COVID test, but we are actively gathering data and will provide updates as information becomes available.
What does a negative T-Detect COVID test mean?
A recent study demonstrated 95% of patients tested positive for T cells up to five months after a confirmed positive PCR test.1 Clinically validated data for T-Detect COVID performance beyond five months is not available yet. Therefore, it is possible that individuals who received a positive PCR result for COVID-19 more than five months ago no longer have sufficient T cells to detect past infection.
What does “no result available” mean?
In some instances, we are not able to definitively determine a positive or negative result. If this happens, your result will say, “no result available.” Call our Clinical Services team at 833-T-DETECT (833-833-8328) to discuss redoing your test at no cost.
How much does this test cost?
The T-Detect COVID test is available to individuals at a special self-pay test price of $150, as part of our commitment to supporting testing options during the current public health emergency and to improve our understanding of the role of T cells in COVID-19.
Additional fees include test authorization ($9) and blood draw (on-site lab: $60 or in-home: $140).
The price does not represent the usual and customary customary charge for the T-Detect COVID test and is subject to change. The T-Detect COVID test is FSA/HSA eligible.
Will insurance cover costs for the test?
The T-Detect COVID test is not currently covered by insurance. The patient is responsible for blood draw fees, copays for doctor visits, and any additional associated costs. The T-Detect COVID test is FSA/HSA eligible.
