Scotland's Chief Medical Officer has defended the decision to test the Princes of Wales for coronavirus, saying there were "very good reasons" behind the move.
Dr Catherine Calderwood spoke after news that the heir to the throne had been tested for Covid-19 sparked an angry backlash from some.
While some medical workers who are self-isolating have been unable to get tested to see if they could come back to work, both Charles, 71, and his wife Camilla, 72, were tested on Monday.
The Royal couple are currently staying at the Birkhall estate in Aberdeenshire, with Camilla separating herself from her husband after she tested negative.
Speaking about Charles on BBC Radio Scotland's Good Morning Scotland programme, Dr Calderwood said: "I have spoken to the team in Grampian who were looking after the individual.
"My understanding is there were very good reasons for that person and his wife to be tested, and obviously I wouldn't be able to disclose anything else that I know because of patient confidentiality."
The Prince of Wales – who is known as the Duke of Rothesay in Scotland – has become the highest profile coronavirus case in the country, after Clarence House said he had tested positive for the virus.
He is displaying "mild symptoms" of the illness but is in good health and spirits as he self-isolates at Birkhall, a spokesman said.
A source added "medical advice is that it is unlikely to escalate into a more serious case".
SNP MSP Joan McAlpine said she wished Charles a "speedy recovery", but added: "Given that his symptoms are said to be mild, like many I wonder how he was tested when many NHS and social care workers cannot get tested.
"My nephew, who has serious asthma and a chest infection, was recently refused a test."

With tourists being urged to stay away from remote areas of Scotland during the outbreak, former SNP MP George Kerevan was more critical, branding Charles an "arrogant fool".
He tweeted: "This billionaire land owner disobeyed guidance to stay home to avoid spreading virus, went to second home in Scotland, is now infected and has infected others.
"Indy Scotland must be a republic and tax this arrogant fool."
