• T cells are the first responders of the adaptive immune system and activate the antibody response. While antibodies naturally wane and are detectable in the shorter term, T cell responses persist in the blood long after antibody responses wane.¹
• The T-Detect COVID Test can detect T cells in your blood sample that can remain for up to several months after symptoms appear.^1,2,3

• 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.

• In preliminary studies, when the T-Detect COVID Test was compared with serology testing:
  1. In one study, ~2 months after PCR Diagnosis, the T-Detect COVID test detected 97% of COVID positive patients, while the serology (antibody) tests had a range of 77-97% detecting of COVID positive patients.¹
  2. In another study, 5+ months after PCR diagnosis, the T-Detect COVID test detected 95% of COVID positive patients, while the serology (antibody) tests had a range of 52-71% in detection of COVID positive patients.²
  3. In studies, T-Detect COVID Test showed a specificity of >99%.²

Samples are processed within 5-7 days of receipt in the lab. Estimated total time for results is 7-10 days from the time of your blood draw.

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, while a negative result indicates that past exposure to SARS-CoV-2 probably did not occur.

A T cell response is typically detectable in blood several days after initial infection. How long this response lasts post-infection and the implication for immunity are not known. In this study, T cells were shown to persist in the blood for more than six months after initial infection¹and studies of other coronaviruses show T cells responses can persist for several years.^2,3

Mobile phlebotomy is a mobile blood draw service in which a certified phlebotomist (someone trained to draw your blood) visits your home to collect a blood sample.

ExamOne is a national mobile phlebotomy service provider that Adaptive Biotechnologies has partnered with to help provide blood draw services to patients.

• The T-Detect COVID Test can help you understand if you’ve had a recent or past COVID infection.
• The T-Detect COVID Test can provide answers if:
  • You still have symptoms and wondering if it is COVID?
  • You never got tested, but are concerned that you might have had COVID?
  • Got tested, but not sure you trust your test results
  • You are interested in supporting COVID research

The T-Detect COVID Test is available to be prescribed by healthcare professionals in all U.S. states, except for state of New York at this time. The state of New York requires laboratories conducting clinical testing on specimens from New York to obtain a special clinical laboratory permit. We are actively working with the proper regulatory bodies to gain the necessary approvals and we expect to provide access to the test in New York in early 2021. For updates on when the test is available to be prescribed in the state of New York,  please sign-up for email updates here.

The T-Detect COVID Test is only available in the United States and is not available in U.S. Territories.

The T-Detect COVID Test is available at a special price of $150* as part of our commitment to support testing options during the public health emergency and to improve our understanding of the role of T cells in COVID-19.

*The price does not represent the usual and customary charge for the T-Detect COVID Test, requires pre-payment, and is subject to change. The T-Detect COVID Test is currently not covered by health insurance. The T-Detect COVID Test is FSA/HSA eligible.

• The T-Detect COVID Test is not currently covered by insurance. Patient is responsible for blood draw fees, co-pay for doctor visit, and any additional associated costs. The T-Detect COVID Test is FSA/HSA eligible.
