A coronavirus testing project by Google has been thrown into confusion over comments made by US President Donald Trump.

Axar.az reports citing foreign media.

He said the company was developing a website for all Americans to check whether they should get tested.

However, Google's sister company Verily had actually been working on a pilot limited to California's Bay Area.

Two sites launch on Monday - but only the localised one contains screening features for tests.

The Verily site was "in the early stages of development and planning to roll testing out in the Bay Area, with the hope of expanding more broadly over time", the company said in a statement.

"We will take the time to assess operations at pilot sites in the Bay Area before rolling out to additional sites."

The website, Project Baseline, launched today but appears to already have run out of appointments for testing.

The other site is being built by Google itself.
