The Australian Medical Association WA has called on the government to complete the testing of cladding at WA hospitals as soon as possible after Fiona Stanley Hospital bosses confirmed the presence of potentially dangerous cladding.

In an email sent to all staff on Monday Fiona Stanley Fremantle hospitals group executive director Neil Doverty and south metro health service chief executive Paul Forden said aluminium composite panels had been used on the state's largest hospital.

The cladding is the same material experts believe may have added to the ferocity of the fire that killed 72 people in the Grenfell tower fire in London in 2017.

"Specialist fire engineers have confirmed the presence of Aluminium Composite Panel panels on the exterior of the Fiona Stanley Hospital," the email read.
