T-SPOT®Discovery SARS-CoV-2: Proven T cell technology

The T-SPOT Discovery SARS-CoV-2 kit uses proven T cell technology to detect and measure the strength of the T cell response to SARS-CoV-2. We have over 17 years’ experience in developing leading T cell technology, and work in collaboration with government bodies including Public Health England and UK Vaccines Task Force.

T cells in COVID-19

Helen Fletcher, Professor of Immunology at the London School of Hygiene and Tropical Medicine, talks about the importance of T cells in COVID-19 and answers some topical questions, including: What role might T cells have in COVID-19? Are antibodies or T cells more important to COVID-19? How might T cells be used for testing?

Is there a role for T cells in the assessment of SARS-CoV-2 infection status?

Hear from Dr Ruth Brignall, Medical Science Liaison at Oxford Immunotec, discussing how T cell testing and diagnostics have been an incredibly important focus of the scientific community’s response to the COVID-19 pandemic including the role of T cells in the immune response to SARS-CoV-2 infection, the principles of cell-mediated immunity testing and the T-SPOT Discovery test for SARS-CoV-2 and its potential role in assessing infection status during the COVID-19 pandemic.

Why choose the T-SPOT technology?

The T-SPOT technology is unique as the only globally regulated ELISPOT platform, currently being used clinically for identifying and measuring T cells. The platform makes highly standardised measurement of the T cell response easy through centralisation of fresh blood samples from different study locations, as well as enabling automation leading to ease of use and scalability. These attributes are essential in large-scale studies, or for more widespread testing.

How the T-SPOT technology works

Our T-SPOT test based on ELISPOT technology is normalised for both cell number and culture conditions. This means that the test standardises the number of cells and removes serum factors that could adversely affect results, making it the most sensitive and specific test for T cell measurement.

  1. A blood sample is collected using routine phlebotomy and a standard blood collection tube from which a subset of white blood cells, known as peripheral blood mononuclear cells (PBMCs), are isolated. The cells are washed, counted and normalised to create a standard cell suspension.
  2. A standard number of cells are added into specially designed plates and stimulated with antigens specific to the disease under study. Cells responding to these antigens release a chemical messenger known as a cytokine.
  3. Cytokine antibodies are used to directly capture the cytokine as it is released by the cells. A secondary labelled antibody is added and binds to the captured cytokine.
  4. A detection reagent is added and reacts with the secondary labelled antibody. This reaction produces spots, which are a footprint of where the cytokine was released. Spots are then enumerated.
