Her mother Sonya kept a constant vigil at her bedside at nearby Charing Cross Hospital.
The actress played nurse Sandy Harper in BBC One's medical drama. Mr Calil plays her boyfriend, drug dealer Sean Hunt.
The BBC had considered dropping Tuesday's episode because of her serious condition. The programme only featured one scene with her.
But it went ahead with the transmission, after getting the go-ahead of her family.
Mal Young, the BBC's Controller of Drama Series, led the tributes to the young actress.
"Everyone at Holby City, and indeed, across the BBC, are devastated by this news," he said.
"Laura was a much loved, talented and respected actress. She brought so much to the role with her infectious enthusiasm, dedication and 100% professionalism.
"Television has lost a talent who had so much more to give."
Laura's agent, Michele Milburn, said: "She had a unique talent, and I am certain was only at the start of what would have been a brilliant career.
"However, her greatest gift, was her ability to bring out the best in all who were lucky enough to know her."

Lorraine Heggessy, Controller of BBC1, described Sadler as a "sweet, modest, hard working girl".
"I'm devastated that we have lost such a talented young actress. When I first met Laura on Grange Hill it was clear she had enormous potential."
Holby City, a spin-off from hospital drama Casualty, is watched by millions of people every week.
The actress had her first major role in the children's show Grange Hill, before joining Holby City in 2000.
Ms Sadler had also appeared on TV in Jane Eyre, Inspector Morse, Ruth Rendell Mysteries, and Belfry Witches.
