COVID-19 tests are here to stay even though the vaccine rollout is continuing at pace, while some experts reckon the diagnostics market has yet to peak.
Boris Johnson suggested rapid lateral flow assays could be used to support businesses that have been shuttered for nearly a year, such as nightclubs and theatres.
"That, in combination with vaccination, will probably be the route forward," he said at a press conference, although he noted it is still “early days", with "lots of discussions still to be had".

genedrive recently announced partner Beckman Coulter Life Sciences will sell its testing technology in the US, opening a new sales channel.
The automated solution can process 1,000 PCR samples per workstation over a standard eight-hour day, requiring in the process the equivalent of just half a full-time technician.
PCR testing is the most common type of testing as it provided the highest levels of accuracy, but is expensive and requires experienced professionals and some results can take days to process.
Lateral flow diagnostics, although not always as accurate as other technologies, can provide cheap and rapid results and be administered without training.
Companies offering or developing COVID-19 lateral flow tests (LFT) include Avacta Group PLC (LON:AVCT), Omega Diagnostics Group PLC (LON:ODX), Abingdon Health plc (LON:ABDX) and Immunodiagnostic Systems Holdings PLC (LON:IDH).
MagnifEye is an AI-powered software to read test results on smartphones; its algorithm detects lines that are difficult to read, including those not visible to the human eye, with the goal to improve accuracy.
“The encouraging progress on vaccines has prompted fears over the sustainability of this market; however, we believe these fears are unwarranted,” analysts at broker finnCap (LON:FCAP) said last month.
“We believe the market has yet to peak and will do so in 2021, but will remain strong into 2022 and beyond. Overall, it is likely that COVID-19 will be a part of our lives for years to come and may even be a perpetual presence – and as long as this remains the case, COVID-19 testing will be an important tool for keeping the disease in check and avoiding outbreaks.”
