T cell detection is a new tool in the fight against COVID-19

To protect patients from COVID-19, we must first understand and control the infection. Cell mediated immunity (CMI) is an enduring and reliable marker of the adaptive immune response after COVID-19 vaccination. T cell responses may provide a more sensitive way to monitor immune responses to SARS-CoV-2 vaccination than serological assays alone.

Why T cells? Learn the answer from top scientists

In the fight against COVID-19, antibodies generated in response to a vaccine have taken center stage. What about the other arm of the adaptive immune response – T cells? T cells hunt and kill virus-infected cells and trigger cascades of other immune reactions, making them a critical part of the immune response.

Join three experts as they describe their latest research into SARS-CoV-2 T cell responses – and challenge us to look at T cells differently.

Trusted QuantiFERON technology

QuantiFERON SARS-CoV-2 (QFN SARS) is a qualitative assay that uses specialized blood collection tubes, containing peptide antigens that stimulate immune cells using SARS CoV-2 specific proteins. Whole blood is collected into each of the QFN SARS Blood Collection Tubes, which include a Nil tube, Ag1 tube, Ag2 tube and Mitogen tube.

Flexible workflow, reliable results

Blood can be drawn directly into the QFN SARS Blood Collection Tubes or into a single Lithium- or Sodium-heparin tube, allowing up to 53 hours available from sample collection to incubation. The amount of IFN-γ produced in response to SARS-CoV-2-specific T cell stimulation is measured using enzyme-linked immunosorbent assay (ELISA).
