Principle of the Immuno-T™ test
The Immuno-T™ test is used to determine whether an individual possesses T cell reactivity to the selected test antigens. This T cell response may have arisen through exposure, prior infection, vaccination, or antigen cross-reactivity. For example, prior scientific evidence indicates that the T cell response measured by the Immuno-T test can identify an individual’s risk of testing positive for COVID-19 in the 6 months following the test1.
T cells can be reactivated in vitro by exposure to antigens causing the release of Interferon-gamma (IFN-ꙋ) into the blood plasma, which can be measured in a sample of plasma via Enzyme Linked Immunosorbent Assay (ELISA). Reactive T cells can be identified in fresh venous blood collected into lithium- or sodium-heparin blood collection tubes.
Simple Process
COVID-19 Immuno-T™
Drawing on our expertise in measuring adaptive immune responses to viruses, ImmunoServ has created the COVID-19 Immuno-T™ test, a simple scalable whole blood-based assay for measuring T cell responses to SARS-CoV-2.
The test has shown that the magnitude of venous or capillary blood-derived SARS-CoV-2-specific T cell response is an important correlate of protection, accurately determining COVID-19 immunity1. It has been used in multiple research studies to measure SARS-CoV-2-specific T cell responses in healthy donors2, cancer patients2, people with multiple sclerosis3 and other immune compromised patients4.
