A Brisbane company’s at-home COVID-19 testing kits have been recalled in the United States after returning false positive results.

The kits developed by Brisbane Biotech manufacturer Ellume, which was approved by the US Food and Drug Administration for emergency distribution last year, despite not being available for use in Australia.

Ellume Chief Executive Dr Sean Parsons says the recall is localised to a small number of kits manufactured in between February and June, and were distributed from April to August.
