London, U.K.-based diagnostics company LumiraDx has earned a CE mark for its SARS-CoV-2 Ag Ultra antigen test.

The Ultra test provides digital results in five minutes with high sensitivity, making it possible to complete up to 80 tests per eight-hour day, or up to 10 per hour, on a single LumiraDx instrument.

Improvements in the Ultra test strip design allow for higher sample volumes to enter the test strip chambers to increase detection levels and to achieve faster reaction times and increased precision, the company said.

The company also reported that another of its rapid COVID-19 antigen assays, the LumiraDx SARS-CoV-2 Ag Test, has received an Emergency Use Listing from the World Health Organization.
