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.

Knowledge is health

Fasting is not necessary for this test. Take the test at least 14 days after symptom onset or vaccination. If current COVID infection is suspected, you should do a PCR swab test.

No hidden costs

Everything from the in-clinic blood draw and tracked shipment of samples to the lab, through to delivery of the results and medical report is included in the price.

Professional testing

This test is performed as an in-clinic blood draw by a trained health professional and the samples are analysed by UKAS accredited labs.

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).

“I bought a general health monitoring test for prevention reasons. I have always had high cholesterol but did not know to what extent it could indicate cardiovascular risk. With Melio I have learned a lot about health and healthy habits.”
