A new at-home coronavirus test, developed by Brisbane company Ellume, has been approved for emergency use in the United States.

The Ellume COVID-19 Home Test is designed to detect traces of the virus from a nasal swab sample from an individual as young as two years old.

Ellume Chief Executive Dr Sean Parsons said they were still working on commercial distribution for Australia, but have received considerable interest from universities eager to have students return to campus, and sporting events wanting to test spectators.
