TestCard and SureScreen, together with Guy’s and St Thomas NHS Foundation Trust, have co-created a brand-new app to enable reliable and safe COVID-19 antigen testing and recording of results for visitors, patients and staff.

The introduction of this application will improve visitor and patient safety and flow, helping to support this NHS trust through the winter period.

“A smartphone app has been developed to enable reliable and safe COVID-19 antigen testing.“

A smartphone can be turned into a clinical-grade scanner through the TestCard’s ClearScreen app, which captures and analyses the familiar lateral flown test without the need for individual interpretation and manual result recording. The app provides an invalid, negative or positive result, having checked every step has been undertaken correctly using a valid and in-date cassette. In addition, it enabled record-keeping in hospital NHS electronic patient records, compliant with Public Health England’s reporting requirements. To make the result more secure and safer, it is securely retained for traceability.

Clinical innovations and disruptive technologies lead in the Centre for Clinical Infection and Diagnostics Research, Guy’s and St Thomas’, Dr Rahul Batra, stated: “Lateral flow devices have always had the potential to play an important role in COVID-19 disease surveillance and early diagnosis. However, in the clinical space, they have been hampered by their ability to be administered, interpreted and reported in an automated and standardised fashion to the patient record. We have worked closely with TestCard and SureScreen to not only create a highly sensitive and specific LFD but to also develop the corresponding reporting application that allows for the trained users to administer the test, return a standard interpretation, and provide an automated and reviewable result to the patient record. As LFD testing is now a core component of any patient pathway at Guy’s and St Thomas’ requiring an admission, a significant procedure or an intervention involving the airway, we feel that the introduction of this application will lead to improved patient/visitor flow and safety, thus allowing us to offer a wider range of inpatient and outpatient services to our community.”

Director of SureScreen, David Campbell, stated: "We have been delighted that our COVID antigen tests have helped clinicians across the world with providing quick and accurate information. We are excited to see how using the test with this platform allows for integration into digital platforms, helping reduce the administration of reporting results during routine testing.”
