Oxford Immunotec is a global diagnostics company and part of PerkinElmer group. We’re the only company in the world offering regulated ELISPOT assays for T cell measurement, with approval around the globe. Our leading product, the T-SPOT.TB test, is used for diagnosing infection with Tuberculosis, the world’s largest cause of death from infectious disease.
Our proven T-SPOT technology has also been used to develop T cell tests for COVID-19, both for research use - T-SPOT Discovery SARS-COV-2 kit (RUO) and for IVD use - the T-SPOT.COVID test (CE marked). They are both used to detect a T cell response to SARS-CoV-2. The T-SPOT.COVID test has been shown to detect evidence of a T cell-mediated immune response to SARS-CoV-2 infection in PCR positive patients with a negative serology test result.
