How 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
