Oxford Immunotec has released the T-SPOT.COVID test, a CE marked ELISPOT based test to detect a cell mediated (T cell) immune response to the SARS-CoV-2 virus in human whole blood. The company has also submitted an Emergency Use Authorization (EUA) request to the US Food and Drug Administration (FDA) for the test. The test can also be used alongside serology tests to support clinical assessment of individuals who present with suspected Covid-19 but may be PCR negative.

Abbott has announced that its Alinity m Resp-4-Plex molecular assay has been authorised by the FDA for EUA. The test is designed to detect the SARS-CoV-2 virus, influenza A, influenza B and respiratory syncytial virus (RSV) all at once. These viruses have similar symptoms but require different treatments. The test has received the CE mark and is approved in countries outside the US.

IdentifySensors Biologics, a Purdue University-affiliated technology company,  has entered into a new collaboration with the Purdue Research Foundation (PRF). IdentifySensors is currently developing a diagnostic platform for the detection of the SARS-CoV-2 virus. The company is expected to open an office in Purdue’s Discovery Park District, with the foundation expected to invest $50,000 in IdentifySensors. The company had approached Purdue earlier to help in the development of a nanosensor to detect spoilage and specific pathogens in the food supply chain.
