Why take this test?

A new way to test COVID-19 immune response

This test is a good complement to antibody testing to get a more comprehensive picture of your immune response after a COVID infection. The antibody test assesses the B-cell response, while the T-Spot® COVID test assesses the T-cell response.

Markers included in the analysis.

T cells are part of our adaptive immune system and play a big role in immune regulation, viral recognition and viral destruction. T cells can either kill the virus themselves (cytotoxic T-cells) or interact with B cells (helper T cells) to enable them to produce antibodies against the virus. The T-Spot® COVID test is a CE-marked venous blood test that looks for an immune response from T-cells to COVID-19. It determines whether the T cells are sensitised to SARS-CoV-2, the virus that causes COVID-19. T cell sensitisation can be caused by either previous exposure or vaccination against COVID-19. The T-Spot® COVID test should be undertaken at least 14 days after symptom onset or vaccination. If current COVID infection is suspected, you should do a PCR swab test. The test should only be taken on weekdays (Monday-Friday).
